UPC817CG-D04-T

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

UPC817CG-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 passive Anode of the input LED; the input forward current is rated at 60 mA with a 1 A peak pulse (1 µs) and reverse voltage of 6 V.
2 K passive Cathode of the input LED; the input reverse voltage is rated at 6 V and the forward voltage is typically 1.2 V to 1.4 V at IF = 20 mA.
3 E passive Emitter of the output phototransistor; the emitter-collector voltage is rated at 6 V (VECO).
4 C passive Collector of the output phototransistor; the collector current is rated at 50 mA and the collector-emitter voltage at 35 V (VCEO).
