  • Available in through hole package TO-247, the TM8050H-8W is an 800 V SCR thyristor suitable for applications where high power switching (IT(RMS) = 80 A) and low power dissipation (VTM = 1.55 V at 160 A) are key features. These features make it ideal for motorbike voltage regulator, by-pass AC switch, controlled rectifier bridge, solid state relay, battery charger, welding equipment and motor driver applications.

    Key Features

    • High junction temperature: Tj = 150 °C
    • Blocking voltage: VDRM = VRRM = 800 V
    • Nominal current: IT(RMS) = 80 A
    • Gate triggering current: IGT max. = 50 mA
    • High noise immunity: dV/dt > 1 kV/µs
    • Through hole package TO-247
    • Increase of thermal margin due to extended Tj up to 150 °C
    • Low ID and IR in blocking state
    • Ecopack2 (includes halogen free & RoHS compliance)
