Microsemi udvider SiC-porteføljen

Microsemi fortsætter udvidelsen af Silicon Carbide (SiC) produktporteføljen med den næste generation af 1200 V SiC MOSFETs og 700 V Schottky Barrier dioder (in english).

Microsemi Corporation has 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.

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, says Leon Gross, vice president and business unit manager for Microsemi's Power Discretes and Modules business

- 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

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.
