Vishay, VOR1142B4 MOSFET Output Optocoupler, Through Hole, 4-Pin DIP

The VOR1142 is a 400 V single channel normally open optically isolated solid-state relay (SPST - 1 form A). Based on hybrid architecture which allows fast switching times with a wide operating ambient temperature range. A high efficient GaAlAs IRED enables low forward current on the input side. On the output side high performance MOSFET switches provide a low RON and can switch both DC and AC signals.
