BT1M120

1,200 V SiC MOSFETs for power conversion

Application & Technical Summary

SiC mosfet

The BT1M120 family of silicon carbide switches handles voltages up to 1,200 V. The packaged versions are designed for high power applications like on-board chargers, DC/DC converters and inverters in (hybrid) electric vehicles with system voltages around 800 V.

The robust MOSFETs reduce conduction and switching losses and allow for higher switching frequencies.

For bare-die applications such as inverter modules, also non-packaged chip versions are available.
