AT4N26-CUH-D
AOTE · Transistor, Photovoltaic Output Optoisolators · DIP-6
AT4N26-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 | Anode of the input infrared LED; recommended forward current is 5 to 15 mA, absolute maximum IF is 50 mA. |
| 2 | Cathode | passive | Cathode of the input infrared LED; maximum reverse voltage VR across the LED is 6 V. |
| 3 | NC | unconnected | No internal connection. |
| 4 | Emitter | passive | Emitter of the output phototransistor; maximum emitter-collector voltage VECO is 7 V. |
| 5 | Collector | passive | Collector of the output phototransistor; VCEO is rated 30 V absolute maximum and collector current IC up to 100 mA. |
| 6 | Base | passive | Base of the output phototransistor, available for optional bias or noise control; collector-base voltage VCBO is rated 70 V. |
