Vishay Intertech · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

VOL618A-3X001T from Vishay Intertech, 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 A input Anode of the GaAs infrared emitting diode, where the forward current IF is limited to 60 mA and the reverse voltage VR to 6 V.
2 C passive Cathode of the GaAs infrared emitting diode, where the reverse voltage VR is limited to 6 V and the forward surge current IFSM to 1.5 A for tp < 10 µs.
3 E passive Emitter of the silicon planar phototransistor, where the emitter-collector voltage VECO is limited to 7 V.
4 C output Collector of the silicon planar phototransistor, where the collector-emitter voltage VCEO is limited to 80 V and the collector current IC to 50 mA.
