SFH610A-2

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

SFH610A-2 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 input is rated for a reverse voltage VR of 6 V and a DC forward current IF of 60 mA.
2 C passive Cathode of the GaAs infrared emitter diode; the input is rated for a reverse voltage VR of 6 V and a DC forward current IF of 60 mA.
3 E passive Emitter of the silicon phototransistor output; the output is rated for a collector-emitter voltage VCEO of 70 V, an emitter-collector voltage VECO of 7 V and a collector current IC of 50 mA.
4 C passive Collector of the silicon phototransistor output; the output is rated for a collector-emitter voltage VCEO of 70 V, an emitter-collector voltage VECO of 7 V and a collector current IC of 50 mA.

CAD (KiCad official)

  • Symbol: SFH610A-2
  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: sfh610a-2-etched.step / sfh610a-2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sfh610a-2.step / sfh610a-2.glb are the bare package body.
