  • Available in high power package (TO-247), the device is suitable in applications where power switching (IT(RMS) = 80 A at TC = 126 °C) and power dissipation (VTM = 1.55 V at 160 A) are critical, such as motorbike voltage regulator, by-pass AC switch, controlled rectifier bridge, solid state relay, battery charger, welding equipment and motor driver applications. The TM8050H-8W is available in through hole TO-247 package.

    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
    • Ecopack®2 (includes halogen free & RoHS compliance)
    • Increase of thermal margin due to extended Tj up to 150 °C
    • Low ID and IR in blocking state
