AOTE · Transistor Output Optocoupler · DIP-4
AT852-CuH-D from AOTE, 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 | Anode | passive | Anode of the input infrared LED, driven with a forward current of 5 to 15 mA recommended (50 mA absolute maximum). |
| 2 | Cathode | passive | Cathode of the input infrared LED, with a reverse voltage limit of 6 V. |
| 3 | Emitter | passive | Emitter of the output Darlington phototransistor, with a maximum emitter-collector voltage of 7 V. |
| 4 | Collector | passive | Collector of the output Darlington phototransistor, with a collector-emitter voltage of 350 V maximum and a collector current of 150 mA maximum. |
