DESCRIPTION

The VO4158 consists of a GaAs IRLED optically coupled

to a photosensitive 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 phototriac zero crossing family uses a proprietary

dV/dt clamp resulting in a static dV/dt of greater than

5 kV/μs.

The VO4158 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.
