SFH615A-3

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

SFH615A-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 passive Anode of the GaAs infrared emitter diode; the absolute maximum DC forward current is 60 mA and the reverse voltage is 6 V.
2 C passive Cathode of the GaAs infrared emitter diode; the emitter is rated for 60 mA DC forward current and 70 mW LED power dissipation at 25 °C.
3 E passive Emitter of the silicon planar phototransistor detector; the emitter-collector voltage VECO is rated at 7 V maximum.
4 C passive Collector of the silicon planar phototransistor detector; the collector-emitter voltage VCEO is rated at 70 V and the collector current IC at 50 mA.
