EL357N

Everlight Elec · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

EL357N from Everlight Elec, 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 Anode passive Anode of the input infrared emitting diode; the isolation test note on page 2 shorts pins 1 and 2 together for the input side.
2 Cathode passive Cathode of the input infrared emitting diode; the device has a reverse voltage rating of 6 V and the datasheet states it is not designed for reverse operation.
3 Emitter passive Emitter of the output phototransistor; the emitter-collector breakdown voltage BVECO is specified at a minimum of 7 V (IE = 0.01 mA).
4 Collector passive Collector of the output phototransistor; the collector-emitter breakdown voltage BVCEO is specified at a minimum of 80 V (IC = 0.1 mA) and the collector current rating is 50 mA.

CAD (KiCad official)

  • Symbol: EL357N
  • Footprint: Package_SO:SOP-4_3.8x4.1mm_P2.54mm
  • 3D model: SOP-4-2.54mm (KiCad packages3D, STEP)
  • 3D model files: el357n-etched.step / el357n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); el357n.step / el357n.glb are the bare package body.
