Phototriac Optocouplers provide dV/dt greater than 5 kV/µs.

Encased in 6-pin DIP package, zero-crossing Series VO4157 and VO4158 consist of GaAs infrared LED that is optically coupled to photosensitive ZC TRIAC detector chip, minimizing EMI noise harmonics. Non-zero-crossing Series VO4257 and VO4258 can trigger any time during ac phase cycle and turn off at next zero crossing. Both families have trigger currents of 1.6 mA and are suited for switching ac...
