VO4257 - Optocoupler

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

VO4257 Features

* High static dV/dt 5 kV/µs

* High input sensitivity IFT = 1.6, 2.0, and 3.0 mA e3

* 700 and 800 V blocking voltage

* 300 mA on-state current

* Isolation Test Voltage 5300 VRMS A1 C2 NC 3 6 MT2 5 NC 4 MT1 i179035 Agency Approvals

* UL1577, F
