VO4257/VO4258 - Optocoupler, Phototriac Output, High DV/dt, Low Input Current - Vishay Optocouplers

VO4257/VO4258 - Optocoupler Phototriac Output, High dV/dt, Low Input Current - Vishay Optocouplers VO4257 The VO4257 VO4258 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/s The VO4257 VO4258 phototriac isolates low-voltage Logic from 120, 240, and 380 VAC lines to control resistive, inductive, or capacitive loads including motors, solenoids, high current Thyristors or Triac and relays.
