ELM453

Everlight Elec · Transistor, Photovoltaic Output Optoisolators · SOP-5

ELM453 from Everlight Elec, in a SOP-5. 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 infrared emitting diode; the input is rated for a forward current of 25 mA continuous and 50 mA peak (50% duty, 1 ms), and the device is not designed for reverse operation.
3 Cathode passive Cathode of the infrared emitting diode; the input reverse voltage rating is 5 V, but the device is not designed for reverse operation.
4 Gnd power_in Ground connection on the output side of the photocoupler, shorted to pins 5 and 6 in the isolation test; the datasheet gives no separate electrical limit for this pin.
5 Vout output Output transistor collector (open-collector style output) with an output voltage rating of -0.5 to 20 V, average output current of 8 mA and peak output current of 16 mA.
6 VCC power_in Supply voltage for the detector with an absolute maximum rating of -0.5 to 30 V.
