mSiC™ Discrete MOSFET Series

Microchip high-voltage silicon carbide MOSFETs are ideal for rugged and efficient power conversion

Image of Microchip mSiC™ Discrete MOSFET SeriesThe Microchip mSiC™ MOSFET series is designed for medium- to high-voltage power systems requiring high efficiency, a compact size, and robust reliability. These devices leverage silicon carbide technology to minimize conduction and switching losses, enabling higher switching frequencies and reducing thermal management complexity compared to silicon MOSFETs and IGBTs.

The series spans voltage ratings from 700 V to 3,300 V and supports junction temperatures up to +175°C. All families share core attributes like avalanche ruggedness, short-circuit withstand capability, and stable body diode performance. However, the MA, MB, and MC families offer distinct optimizations for different design priorities, from cost-sensitive industrial systems to high-performance automotive and renewable applications.

MA Series Features
  • Targets ultra-high-voltage applications (up to 3,300 V)
  • Optimized for minimal RDS(ON) at high gate drive voltages (18 V to 20 V)
  • Ideal for grid infrastructures, traction drives, and aerospace systems
MB Series Features
  • Broad industrial and automotive coverage (typically 1,200 V to 1,700 V)
  • Recommended gate drive: +18 V (on) and -5 V (off)
  • Balances efficiency and cost for motor drives, EV chargers, and renewable inverters
MC Series Features
  • Similar voltage range to MB but integrates a gate resistor for improved switching stability
  • Reduces external component count and simplifies layout for high-frequency designs
  • Preferred for compact converters and systems requiring low EMI
Features
  • Low RDS(ON) across temperature range for high efficiency
  • Avalanche ruggedness and short-circuit capability for fault tolerance
  • Fast switching with low gate charge for high-frequency operation
  • Voltage range: 700 V to 3,300 V
  • High-temperature operation up to +175°C
Applications
  • Industrial motor drives and power conversion systems
  • Renewable energy inverters (solar and wind)
  • EV chargers and hybrid powertrains
  • Smart grid transmission and distribution equipment
  • High-voltage power supplies and welding systems
