  • These standard SCRs are suitable for applications where in-rush current conditions are critical, such as overvoltage crowbar protection circuits in power supplies, in-rush current limiting circuits, solid state relays (in back to back configuration), welding equipment, high power motor control circuits.

    Using clip assembly technology, they provide a superior performance in high surge current capabilities.

    Key Features

    • On-state rms current, IT(RMS): 40 A
    • Repetitive peak off-stat voltage, VDRM, VRRM:
      • 600 V
      • 800 V
    • Triggering gate current, IGT: 35 mA
