Fast turn-off circuit for solid-state relays or the like |
摘要 |
A fast turn-off circuit for solid-state relays or the like. The relay has a photodiode array for controlling the conductivity of an output transistor. A JFET switch closes to discharge the gate of the output transistor when a photodiode array stops producing current. A bipolar transistor switch, upon detecting the JFET switch closure, discharges the photodiode array.
