CYPC817C

OCIC · Transistor, Photovoltaic Output Optoisolators · DIP-4

CYPC817C from OCIC, in a DIP-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Anode passive LED anode (input side); forward current IF max 50 mA, reverse voltage VR max 6 V, VF typ 1.2 V at IF=20mA.
2 Cathode passive LED cathode (input side), returns the input forward current IF (max 50 mA).
3 Emitter passive Phototransistor emitter (output side); emitter-collector voltage VECO max 6 V.
4 Collector passive Phototransistor collector (output side); VCEO max 80 V, collector current IC max 50 mA.
