AOTE · Transistor, Photovoltaic Output Optoisolators · SSOP-4
PC3H4B from AOTE, in a SSOP-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 | Anode/Cathode | passive | One terminal of the input LED, which the datasheet rates for forward current IF = ±50 (printed with unit 'A', most likely mA), so the LED is driven with either polarity via this pin and pin 2. |
| 2 | Cathode/Anode | passive | Other terminal of the input LED, paired with pin 1 for the ±IF drive, with forward voltage VF typically 1.2 V and maximum 1.4 V at IF = ±20 mA. |
| 3 | Emitter | passive | Phototransistor emitter, with emitter-collector voltage rated VECO 7 V and emitter-collector breakdown BVECO of at least 7 V at IE = 10 µA. |
| 4 | Collector | output | Phototransistor collector, rated for collector-emitter voltage VCEO 80 V, with collector current IC printed as 50 (unit 'A', most likely mA) and collector power PC 150 (unit 'W', most likely mW). |
