SFH610A-3

Vishay Intertech · Transistor, Photovoltaic Output Optoisolators · DIP-4

SFH610A-3 from Vishay Intertech, 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 GaAs infrared emitter diode, rated for 60 mA DC forward current (2.5 A surge for t ≤ 10 μs) and 6 V maximum reverse voltage.
2 C passive Cathode of the GaAs infrared emitter diode, the input-side return, with a typical forward voltage of 1.25 V (1.65 V max) at IF = 60 mA.
3 E passive Emitter of the silicon phototransistor, with a maximum emitter-collector voltage VECO of 7 V.
4 C passive Collector of the silicon phototransistor, rated for VCEO of 70 V and 50 mA continuous collector current (100 mA for tp ≤ 1.0 ms).
