Main optocoupler types
This chart shows four key optocoupler types used for isolation and signal transfer. Photo-transistor types like 4N25/4N26 offer simple switching and moderate speed. Photo-Darlington devices such as 4N29M/4N30M provide very high gain for low-current drive but respond slower. Photo-SCR models like 4N39/4N40 are ideal for triggering thyristors in ...
