6N135-L

Lite On · Logic Output Optoisolators · DIP-8

6N135-L from Lite On, 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 ANODE input LED anode; input forward current is rated 25 mA max average, with VF 1.4 V typ to 1.7 V at IF=16 mA.
3 CATHODE input LED cathode; reverse input voltage is limited to 5 V.
4 NC unconnected No internal connection.
5 GND power_in Ground reference of the output detector; a 0.1 µF bypass capacitor must be connected between pin 8 and pin 5.
6 VO output Open-collector output of the phototransistor, low when the LED is on and high when off; output voltage rated 20 V max and collector current 8 mA max.
7 VB power_in Base connection of the output transistor (photodiode bias node) that improves speed.
8 VCC power_in Detector supply voltage, rated 15 V max, requiring a 0.1 µF or larger bypass capacitor to pin 5.
