Product Overview
MSC040SMA120B is a 1200V, 40mohm silicon carbide (SiC) power MOSFET in a 3-lead TO-247 package. It delivers high efficiency with low switching and conduction losses, fast switching speed, and robust avalanche performance. Designed for high-power and high-temperature applications, it is ideal for use in EV chargers, solar inverters, motor drives, and industrial power supplies.
- Low on-resistance RDS(on) reduces conduction losses, improving efficiency and thermal performance
- Supports high-frequency operation for smaller magnetics, higher power density, and lower cost
- Superior avalanche ruggedness and short-circuit withstand time
- HV-H3TRB proven capability ensures long-term reliability in high humidity environments
- Lower VGS and standard package enables improved compatibility with standard gate drivers
- Increased creepage distance (notch) improves safety and reliability in high-voltage designs
