  • Available either in through-hole and surface-mount packages, these devices are suitable for general purpose AC switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits or for phase control operation in light dimmers and motor speed controllers, etc.

    The Snubberless versions (BTA, BTB08_xxxxW and T8 series) are specially recommended for use on inductive loads, thanks to their high commutation performance.
    Logic level versions are designed to interface directly with low power drivers such as Microcontrollers.
    By using an internal ceramic pad, the BTA series provide voltage insulated tab (rated at 2500 VRMS) in compliance with UL standards (file ref.: E81734).

    Key Features

    • On-state rms current, IT(RMS) 8 A
    • Repetitive peak off-state voltage, VDRM / VRRM 600 V to 800 V
    • Triggering gate current, IGT 5 to 50 mA
