IL223AT

Vishay Intertech · Transistor Output Optocoupler · SOIC-8

IL223AT from Vishay Intertech, in a SOIC-8. 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 A input LED anode of the input GaAs infrared emitter, rated for 60 mA forward continuous current and 6.0 V peak reverse voltage.
2 C passive LED cathode of the input emitter, returned to the drive circuit; CTR is tested at IF = 1.0 mA.
3 NC unconnected No internal connection.
4 NC unconnected No internal connection.
5 E passive Emitter of the NPN photodarlington output transistor, with emitter-collector breakdown voltage of 5.0 V minimum.
6 C passive Collector of the NPN photodarlington output transistor, with collector-emitter breakdown voltage of 30 V minimum and 50 mA maximum DC collector current.
7 B passive Base connection of the photodarlington output transistor, with collector-base breakdown voltage of 70 V minimum.
8 NC unconnected No internal connection.
