The STMicroelectronics product is an automotive grade SCR thyristor designed for applications such as automotive on board and stationary battery chargers. This SCR Thyristor, rated for a 40 A RMS power switching, offers superior performances in peak voltage robustness up to 400 V sine wave pulse. Its key features allow the design of functions such as a 56 A RMS AC switch and a 50 A AC DC controlled rectifier bridge.

AEC-Q101 qualified
High junction temperature of 150 degree C
Nominal on state RMS current of 40 A RMS
High EFT noise immunity of 1000 V per μs
Max gate triggering current of 50 mA
Available in D2PAK package
