AN-3001 Optocoupler Input Drive Circuits

The circuit of Figure 13 shows how a PNP transistor is connected as an emitter follower, or common collector, to obtain current gain. When the output of the gate (G1) is low, Q1 is turned on

The amount of current that may pass through the phototransistor is determined by the applied forward bias current of the IR LED or the IRED, despite being entirely separated. While the switch S1 is held open, current flow through the IREDis inhibited, which means no IR energy is available to the p...See more on homemade-circuits Vishay Intertechnology
