GUOXIN JIAPIN SEMICONDUCTOR · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm
GX357NC from GUOXIN JIAPIN SEMICONDUCTOR, in a SOP-4-2.54mm. 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 | Anode of the input infrared emitting diode, with a rated forward current of 50 mA, peak forward current of 1 A (1 us pulse) and reverse voltage of 6 V. |
| 2 | Cathode | passive | Cathode of the input infrared emitting diode, with a typical forward voltage of 1.2 V (max 1.4 V) at IF = 20 mA. |
| 3 | Emitter | passive | Emitter of the output phototransistor, with a maximum emitter-collector voltage of 7 V. |
| 4 | Collector | passive | Collector of the output phototransistor, with a collector-emitter voltage of 80 V max and collector current of 50 mA max. |
