Phototriac Coupler include an infrared emitting diode
(IRED) optically coupled to an output Phototriac.
These devices feature full wave control and are
ideal isolated drivers for medium to high current Triacs.
DIP package provides 5.0kV isolation from input to
output with superior commutative noise immunity.
