  • The TN3050H-12GY-TR is an automotive grade SCR Thyristor designed for applications such as automotive on-board chargers, AC solid state relays and stationary battery chargers.

    Rated for a 30 ARMS power switching, This SCR Thyristor offers superior performance in terms of peak voltage robustness (up to 1400 V) and surge current handling (sine wave pulse up to 300 A). Its key features allow the design of functions such as a 42 ARMS AC switch (dual back-to-back SCRs) and a 38 A average AC-DC controlled rectifier bridge for inrush current limitation.
    Available in D²PAK package, it is ideal for compact SMD designs on surface mount boards or insulated metal substrate boards.

    Key Features

    • AEC-Q101 qualified
    • High junction temperature: Tj = 150 °C
    • AC off state voltage: +/- 1200 V
    • Nominal on-state current: 30 ARMS
    • High noise immunity: 1000 V/μs
    • Max. gate triggering current: 50 mA
    • ECOPACK®2 compliant component
