The VO4154 and VO4156 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,
VO4156 Features
* High static dV/dt 5 kV/μs
* High input sensitivity IFT = 1.6 mA, 2 mA, and 3 mA
* 300 mA on-state current
* Zero voltage crossing detector
* 400 V and 600 V blocking voltage
* Isolation rated voltage 4420 VRMS
* Material categorization: for d
