Everlight Elec · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

EL452 from Everlight Elec, in a SOP-4-2.54mm. 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 input Infrared emitting diode anode; the input forward current IF is rated 60 mA maximum with a peak forward current IFM of 1 A for 10 µs.
2 Cathode passive Infrared emitting diode cathode; the device is not designed for reverse operation, and reverse voltage VR = 4V is applied only to the IR test.
3 Emitter passive Darlington phototransistor emitter; the emitter-collector breakdown voltage BVECO is specified at a minimum of 0.1 V.
4 Collector output High-voltage darlington phototransistor collector; the collector-emitter voltage VCEO is rated 350 V and the collector current IC is rated 150 mA maximum.
