General description

AC Thyristor power switch in a SOT223 surface-mountable plastic package with self-protective capabilities against low and high energy transients

Features and benefits

■ Common terminal on mounting base allows multiple ACTs on shared cooling pad

■ Exclusive negative gate triggering

■ Full cycle AC conduction

■ Remote gate separates the gate driver from the effects of the load current

■ Safe clamping of low energy over-voltage transients

■ Self-protective turn-on during high energy voltage transients

■ Surface-mountable package

■ Very high noise immunity

Applications

■ Contactors, circuit breakers, valves, dispensers and door locks

■ Fan motor circuits

■ Lower-power highly inductive, resistive and safety loads

■ Pump motor circuits
