AT4N31-CuH-D from AOTE, in a DIP-6. 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 | LED anode of the GaAs input diode; the datasheet rates forward current IF at 60 mA, peak forward current IFP at 1 A (1 µs pulse), and reverse voltage VR at 3 V. |
| 2 | Cathode | passive | LED cathode of the GaAs input diode, with the input reverse voltage limit VR of 3 V stated in the ratings. |
| 3 | NC | unconnected | No connection; the datasheet lists this pin as NC and gives no function or limit for it. |
| 4 | Emitter | passive | Emitter of the output Darlington transistor, with emitter-collector voltage VECO rated at 5 V and emitter-base voltage VEBO rated at 8 V. |
| 5 | Collector | passive | Collector of the output Darlington transistor, rated for collector-emitter voltage VCEO of 30 V, collector current IC of 100 mA, and collector power dissipation PC of 150 mW. |
| 6 | Base | passive | Base of the output Darlington transistor; the datasheet gives no separate pin-level limit, only the collector-base voltage VCBO of 50 V and emitter-base voltage VEBO of 8 V. |
