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. |
