Microsemi Continues to Expand Silicon Carbide Product Portfolios with Sampling of its Next-Generation 1200 V SiC MOSFET and 700 V Schottky Barrier Diode Devices

Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced it will be expanding its Silicon Carbide (SiC) MOSFET and SiC diode product portfolios early next quarter, including samples of its next-generation 1200-volt (V), 25 mOhm and 80 mOhm SiC MOSFET devices; next-generation 700 V, 50 A Schottky barrier diode (SBD) and corresponding die. These SiC solutions, along with other recently announced devices in the SiC SBD/MOSFET product families, will be demonstrated June 5-7 in hall 6, booth 318 at PCIM Europe 2018, held at the Exhibition Centre in Nuremberg, Germany.

As Microsemi continues to expand development efforts for its SiC product family, it has become one of the few suppliers providing a range of Si/SiC power discrete and module solutions to the market. These next-generation SiC MOSFETs are ideally suited for a number of applications within the industrial and automotive markets, including hybrid electric vehicle (HEV)/EV charging, conductive/inductive onboard chargers (OBCs), DC-DC converters and EV powertrain/traction control. They can also be used for switch mode power supplies, photovoltaic (PV) inverters and motor control in medical, aerospace, defense and data center applications.

“Fast adoption of SiC solutions for applications such as EV charging, DC-DC converters, powertrain, medical and industrial equipment, and aviation actuation demand a high degree of efficiency, safety and reliability on components used in such systems,” said Leon Gross, vice president and business unit manager for Microsemi’s Power Discretes and Modules business unit. “Microsemi’s next-generation SiC MOSFET and SiC diode families will include AEC-Q101 qualifications, which will insure high reliability while ruggedness is demonstrated by high repetitive unclamped inductive switching (UIS) capability at rated current without degradation or failures.”

According to market research firm Technavio, the global SiC market for semiconductor applications is expected to reach nearly $540.5 million by 2021, growing at a compound annual growth rate (CAGR) of more than 18 percent. The firm also forecasts the global SiC market for automotive semiconductor applications at nearly 20 percent CAGR by 2021. Microsemi is well-positioned with these trends, with its SiC MOSFET and Schottky barrier diode devices avalanche-rated with a high short-circuit withstand rating for robust operation, and the capabilities necessary to enable these growing application trends.

Microsemi’s next-generation 1200 V, 25/40/80 mOhm SiC MOSFET devices and die as well as its next-generation 1200 V and 700 V SiC SBD devices offer customers attractive benefits in comparison to competing Si/SiC diode/MOSFET and IGBT solutions, including more efficient switching at higher switching frequencies as well as higher avalanche/UIS rating and higher short-circuit withstand rating for rugged and reliable operation. For example, SiC MOSFETs are developed with an ideal balance of specific on-resistance, low gate and thermal resistances, and low gate threshold voltage and capacitance for reliable operation. Designed for high yield processes and low parameter variation across temperature, they operate at higher efficiency (in comparison to Si and IGBT solutions) across high junction temperature (175 degrees Celsius) to extend battery systems like those in HEV/EV applications.

The newly sampling devices also offer excellent gate integrity and high gate yield as verified through high temperature reverse bias (HTRB) and time-dependent dielectric breakdown (TBBD) tests, which are part of its AEC-Q101 qualification in progress. Other key features include:

High UIS capability, offering 1.5x to 2x higher than competitive SiC MOSFETs and GaN devices for avalanche ruggedness;
High short-circuit rating ranging from 1.5x to 5x higher than competitor SiC MOSFET devices for more rugged operation;
Up to 10x lower failure-in-time (FIT) rate than comparable Si IGBTs at rated voltage for neutron susceptibility and with comparable performance against SiC competition pertaining to neutron irradiation; and
Higher SiC power density versus Si, enabling smaller magnetics/transformers/DC bus capacitors and less cooling elements for more compact form factor to lower overall system costs.
Demonstrations at PCIM June 5-7 in Hall 6, Booth 318
Microsemi’s product experts will be at the company’s booth at PCIM during show hours to demonstrate its next-generation SiC solutions, and in particular the company’s recently announced next-generation 1200 V, 40 mOhm SiC MOSFET device and 1200V, 10/30/50A SiC diode products.

Spain’s jobless hit four million for first time in five years as pandemic curbs bite

Spain's jobless hit four million for first time in five years as pandemic curbs bite 1

By Nathan Allen and Belén Carreño

MADRID (Reuters) – The number of jobless people in Spain rose above 4 million for the first time in five years in February, official data showed on Tuesday, as COVID-19 restrictions ravage the ailing economy.

Since the onset of the pandemic, Spain has lost more than 400,000 jobs, around two-thirds of them in the hospitality sector, which has struggled with limits on opening hours and capacity as well as an 80% slump in international tourism.

Jobless claims rose by 1.12% from a month earlier, or by 44,436 people to 4,008,789, Labour Ministry data showed, the fifth consecutive monthly increase in unemployment.

That number was 23.5% higher than in February 2020, the last month before the pandemic took hold in Spain.

“The rise in unemployment, caused by the third wave, is bad news, reflecting the structural flaws of the labour market that are accentuated by the pandemic,” Labour Minister Yolanda Diaz tweeted.

Restrictions vary sharply from region to region in Spain, with some shutting down all hospitality businesses, though Madrid has taken a particularly relaxed approach and kept bars and restaurants open.

A total of 30,211 positions were lost over the month, seasonally adjusted data from the Social Security Ministry showed. It was the first month more positions were closed than created since Spain emerged from its strict first-wave lockdown in May.

Still, the number of people supported by Spain’s ERTE furlough scheme across Spain fell by nearly 29,000 to 899,383 in February.

“These figures have remained more or less stable since September, indicating that the second and third waves of the pandemic have had a much smaller effect than the first in this regard,” the ministry said in a statement.

Hotels, bars and restaurants and air travel are the sectors with the highest proportion of furloughed workers, it added.

Tourism dependent regions like the Canary and Balearic Islands have been particularly hard hit, with the workforce contracting by more than 6% since last February in both archipelagos.

The last time the number of jobless in Spain hit 4 million was in April 2016.

Pandemic ‘shecession’ reverses women’s workplace gains

Pandemic 'shecession' reverses women's workplace gains 2

By Anuradha Nagaraj

(Thomson Reuters Foundation) – The coronavirus pandemic reversed women’s workplace gains in many of the world’s wealthiest countries as the burden of childcare rose and female-dominated sectors shed jobs, according to research released on Tuesday.

Women were more likely than men to lose their jobs in 17 of the 24 rich countries where unemployment rose last year, according to the latest annual PricewaterhouseCoopers (PwC) Women in Work Index.

Jobs in female-dominated sectors like marketing and communications were more likely to be lost than roles in finance, which are more likely to be held by men, said the report, calling the slowdown a “shecession”.

Meanwhile, women were spending on average 7.7 more hours a week than men on unpaid childcare, a “second shift” that is nearly the equivalent of a full-time job and risks forcing some out of paid work altogether, it found.

“Although jobs will return when economies bounce back, they will not necessarily be the same jobs,” said Larice Stielow, senior economist at PwC.

“If we don’t have policies in place to directly address the unequal burden of care, and to enable more women to enter jobs in growing sectors of the economy, women will return to fewer hours, lower-skilled, and lower paid jobs.”

The report, which looked at 33 countries in the Organisation for Economic Co-operation and Development (OECD) club of rich nations, said progress towards gender equality at work would not begin to recover until 2022.

Even then, the pace of progress would need to double if rich countries were to make up the losses by 2030, it said, calling on governments and businesses to improve access to growth sectors such as artificial intelligence and renewable energy.

Laura Hinton, chief people officer at PwC, said it was “paramount that gender pay gap reporting is prioritised, with targeted action plans put in place as businesses focus on building back better and fairer”.

Britain has required employers with more than 250 staff to submit gender pay gap figures every year since 2017 in a bid to reduce pay disparities, but last year it suspended the requirement due to the coronavirus pandemic.

German January exports to UK fell 30% year-on-year as Brexit hit - Stats Office 3

BERLIN (Reuters) – German exports to the United Kingdom fell by 30% year-on-year in January “due to Brexit effects”, preliminary trade figures released by the Federal Statistics Office on Tuesday showed.

In 2020, German exports to the UK fell by 15.5% compared to 2019, recording the biggest year-on-year decline since the financial and economic crisis in 2009, when they fell by 17.0%, the Office said.

“Since 2016 – the year of the Brexit referendum – German exports to the UK have steadily declined,” the Office said in a statement.

In 2015 German exports to the UK amounted to 89.0 billion euros. In 2020, German they totalled 66.9 billion euros.

Imports to Germany from the UK totalled 34.7 billion euros in 2020, down 9.6 % compared to 2019.
