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

    This SCR Thyristor, rated for a 30 A RMS power switching, offers superior performance in peak voltage robustness up to 1400 V and surge current handling up to 300 A sine wave pulse. Its key features allow the design of functions such as a 42 A RMS AC switch (dual back-to-back SCRs) and a 38 A average AC-DC controlled rectifier bridge for inrush current limitation.
    Available in through-hole TO-247 package, this power package allows a thermal operation up to 30 A RMS with a higher case temperature of 126 °C.

    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
    • ECOPACK2 compliant component
