T6421DHR Image

The T6421DHR from Digitron Semiconductors is a Bidirectional Triode Thyristor that is ideal for industrial and commercial applications for full wave control of AC loads, control circuits, heater and motor controls, and other switching applications. It has a break-over voltage of up to 400 V and a break-over current of less than 300 A. This MIL-PRF-19500 standard thyristor has a gate trigger voltage of up to 1.35 V and a gate trigger current of 35 mA. It provides greater reliability for industrial switching applications and has a maximum on-state current RMS of 30 A. This RoHS-compliant triac is available in a stud-mount package that measures 44.07 x 14.20 mm.
