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.
