Triac output photocouplers provide a high isolation voltage between input and output Viso of 3,750Vrms (SOP) / 5,000Vrms (DIP6). With two options of zero-crossing and random phase type of triac driver output, it will provide flexibility for circuit designers. Other benefits include high off-State Output Terminal voltage (400V, 600V & 800V) and high critical rate of rise off-state voltage (min 1000V/µs).
