CNY174SR2M

onsemi · Transistor, Photovoltaic Output Optoisolators · PDIP-6

CNY174SR2M from onsemi, in a PDIP-6. 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 Gallium arsenide infrared emitting diode anode; continuous forward current is rated at 60 mA and reverse voltage at 6 V.
2 CATHODE passive Infrared emitting diode cathode; the LED reverse voltage rating is 6 V and continuous forward current is 60 mA.
3 NC unconnected No internal connection shown for this pin in the CNY17x schematic.
4 EMITTER passive NPN phototransistor emitter; emitter-collector voltage (VECO) is rated at 7 V.
5 COLLECTOR passive NPN phototransistor collector; collector-emitter voltage (VCEO) is rated at 70 V with continuous collector current of 50 mA.
6 BASE passive Phototransistor base terminal, connected on the CNY17XM family; base-to-emitter resistance R_BE is used to adjust CTR and switching speed.
