  • Available in SMD D²PAK with anode in backside.

    The TN2540-12G SCR is suitable in industrial applications where high immunity is required with a lower gate current.

    Key Features

    • Max. blocking voltage = VDRM, VRRM = 1200 V
    • IGT maximum = 40 mA
    • High static and dynamic commutation at Tj = 125 °C
      • dl/dt = 50 A/µs
      • dV/dt = 1500 V/µs
    • ECOPACK®2 compliant (RoHS and HF compliance)
