DESCRIPTION

The VO4256 phototriac consists of a GaAs IRLED optically

coupled to a photosensitive non-zero crossing TRIAC

packaged in a DIP-6 package.

High input sensitivity is achieved by using an emitter

follower phototransistor and a cascaded SCR predriver

resulting in an LED trigger current of 1.6 mA for bin D, 2 mA

for bin H, and 3 mA for bin M.

The new non zero phototriac family use a proprietary dV/dt

clamp resulting in a static dV/dt of greater than 5 kV/μs.

The VO4256 phototriac isolates low-voltage logic from

120 VAC, 240 VAC, and 380 VAC lines to control resistive,

inductive, or capacitive loads including motors, solenoids,

high current thyristors or TRIAC and relays.
