PC817B

GOODWORK · Transistor, Photovoltaic Output Optoisolators · DIP-4

PC817B from GOODWORK, in a DIP-4. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Anode input LED anode (input); max forward current IF = 50 mA, typical VF = 1.20 V at IF = 20 mA.
2 Cathode passive LED cathode (input); max reverse voltage VR = 6 V, max reverse current IR = 5 µA at VR = 5 V.
3 Emitter passive NPN phototransistor emitter (output); max emitter-to-collector voltage VECO = 6 V.
4 Collector output NPN phototransistor collector (output); VCEO = 35 V, max IC = 50 mA, CTR 130-260% (Grade B) at IF = 5 mA, VCE = 5 V.
