CY6N136

OCIC · Optocouplers - Phototransistor Output · DIP-8

CY6N136 from OCIC, in a DIP-8. 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 NC unconnected No internal connection.
2 LED+ input LED anode; recommended forward input current IFH is 6.3 to 20.0 mA, with a maximum average of 25 mA.
3 LED- input LED cathode; reverse input voltage must not exceed 5.0 V.
4 NC unconnected No internal connection.
5 GND power_in Ground reference for the output-side detector (transistor emitter).
6 VO output Open-collector output, rated -0.5 to 20 V with 8 mA average and 16 mA peak output current.
7 VB power_in Photodiode base connection, brought out separately to speed up the phototransistor; base current is limited to 5 mA.
8 VCC power_in Supply voltage, recommended 4.5 to 20 V (absolute maximum -0.5 to 30 V).
