UPC817XG-D04-T

UTC Unisonic Tech · Transistor, Photovoltaic Output Optoisolators · DIP-4

UPC817XG-D04-T from UTC Unisonic Tech, 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 A input Anode of the input LED; forward current is rated at 60 mA maximum with 1 A peak for 1 µs pulses, and VF is typically tested at IF = 20 mA.
2 K input Cathode of the input LED; reverse voltage is rated at 6 V maximum (VR).
3 E output Emitter of the output phototransistor; emitter-collector voltage is rated at 6 V maximum (VECO).
4 C output Collector of the output phototransistor; collector current is rated at 50 mA maximum and collector-emitter voltage at 35 V maximum (VCEO).
