S2S4BY0F (SHARP)

The S2S4BY0F is a TRIAC Output Optocoupler with zero crossing TRIAC operating mode. The S2S4 series phototriac coupler include an infrared emitting diode (IRED) optically coupled to an output phototriac. This device features full wave control and are ideal isolated drivers for medium to high current TRIACs. It provides 3.75kV isolation from input to output with superior commutative noise immunity. In order for the phototriac to turn off, the triggering current (IF) must be 0.1mA or less. Intended to be used as triggering device for main TRIACs. For applications with inductive loads such as motors, please use caution in utilizing a zero crossing type phototriac coupler as this may cause undesired operations due to the phase difference between voltage and current of load.
