EL1017

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

EL1017 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, with forward current rated at 60 mA max (IF) and forward voltage of 1.45 V typ. at IF = 50 mA.
2 Cathode passive Cathode of the input infrared emitting diode, with reverse voltage rated at 6 V max (VR).
3 Emitter passive Emitter of the output phototransistor, with emitter-collector voltage rated at 7 V max (VECO).
4 Collector passive Collector of the output phototransistor, rated at 80 V max collector-emitter voltage (VCEO) and 50 mA max collector current (IC).

CAD (KiCad official)

  • Symbol: EL1017
  • Footprint: Package_SO:SOP-4_3.8x4.1mm_P2.54mm
  • 3D model: SOP-4-2.54mm (KiCad packages3D, STEP)
  • 3D model files: el1017-etched.step / el1017-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); el1017.step / el1017.glb are the bare package body.
