PC4SD21YXPDF数据手册隔离器的光隔离器-双向可控硅SCR输出规格书PDF

描述 Description

The PC4SD21YXPDF is a 6-pin zero cross type Phototriac Coupler with SMT gullwing lead form. It include an infrared emitting diode (IRED) optically coupled to an output phototriac. It features full wave control and are ideal isolated drivers for medium to high current TRIACs. It provides 5kV isolation from input to output with superior commutative noise immunity. It is suitable for triggering for TRIACs used to switch ON and OFF devices which require AC loads.
