EL851

Everlight Elec · Transistor, Photovoltaic Output Optoisolators · DIP-4

EL851 from Everlight Elec, 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 Anode passive Anode of the infrared emitting diode (input side), with absolute maximum forward current IF of 60 mA and reverse voltage VR of 6 V.
2 Cathode passive Cathode of the infrared emitting diode (input side), with the same absolute maximum limits of 60 mA forward current and 6 V reverse voltage.
3 Emitter passive Emitter of the phototransistor (output side), with an emitter-collector voltage limit VECO of 7 V.
4 Collector passive Collector of the phototransistor (output side), with a collector-emitter voltage limit VCEO of 350 V and a collector current limit IC of 50 mA.

CAD (KiCad official)

  • Symbol: EL851
  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: el851-etched.step / el851-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); el851.step / el851.glb are the bare package body.
