AC Thyristor power switch in a SOT54 plastic package with self-protective capabilities against low and high energy transients

Features and Benefits
  • Exclusive negative gate triggering
  • Full cycle AC conduction
  • Remote gate separates the gate driver from the effects of the load current
  • Very high noise immunity
  • Safe clamping of low energy over-voltage transients
  • Self-protective turn-on during high energy voltage transients
  • Fan motor circuits
  • Pump motor circuits
  • Lower-power highly inductive, resistive and safety loads
