# S2S5A00F

**Sharp Microelectronics** · Optocouplers - Phototransistor Output · SOP-4-2.54mm

S2S5A00F from Sharp Microelectronics, 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 (IRED); forward current IF max 50mA, reverse voltage VR max 6V. |
| 2 | Cathode | passive | Cathode of the input infrared emitting diode (IRED); the phototriac turns off only when IF is 0.1mA or less. |
| 3 | Anode/Cathode | passive | Phototriac output terminal (bidirectional, polarity-independent) connected to the main triac circuit; VDRM max 600V, RMS on-state current 0.05A. |
| 4 | Cathode/Anode | passive | Phototriac output terminal (bidirectional, polarity-independent) connected to the main triac circuit; VDRM max 600V, RMS on-state current 0.05A. |
