AT815-CuH-D

AOTE · Transistor, Photovoltaic Output Optoisolators · DIP-4

AT815-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 LED anode input; forward current is 50 mA absolute maximum (5 to 15 mA recommended), with VF 1.2 V typ and 1.4 V max at IF=20 mA.
2 Cathode passive LED cathode input; reverse voltage across the LED is 6 V absolute maximum.
3 Emitter passive Darlington phototransistor emitter output; emitter-collector voltage is 7 V absolute maximum.
4 Collector passive Darlington phototransistor collector output; VCEO is 40 V maximum and collector current is 80 mA absolute maximum.
