SFH610A-3 from Vishay Intertech, 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 | A | input | Anode of the GaAs infrared emitter diode, rated for 60 mA DC forward current (2.5 A surge for t ≤ 10 μs) and 6 V maximum reverse voltage. |
| 2 | C | passive | Cathode of the GaAs infrared emitter diode, the input-side return, with a typical forward voltage of 1.25 V (1.65 V max) at IF = 60 mA. |
| 3 | E | passive | Emitter of the silicon phototransistor, with a maximum emitter-collector voltage VECO of 7 V. |
| 4 | C | passive | Collector of the silicon phototransistor, rated for VCEO of 70 V and 50 mA continuous collector current (100 mA for tp ≤ 1.0 ms). |
