EL357C

UMW · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

EL357C from UMW, 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 Infrared emitting diode anode; the datasheet limits forward current to 60 mA continuous and 1 A peak (100 µs pulse, 100 Hz), with reverse voltage rated at 6 V.
2 Cathode passive Infrared emitting diode cathode; the LED reverse voltage is rated at 6 V maximum, with the 60 mA forward current limit applying to the anode-cathode path.
3 Emitter passive Phototransistor emitter; the emitter-collector breakdown voltage (VECO) is rated at 7 V maximum.
4 Collector passive Phototransistor collector; the collector-emitter voltage (VCEO) is rated at 80 V maximum and collector current at 50 mA maximum.

CAD (KiCad official)

  • Symbol: EL357C
  • Footprint: Package_SO:SOP-4_3.8x4.1mm_P2.54mm
  • 3D model: SOP-4-2.54mm (KiCad packages3D, STEP)
  • 3D model files: el357c-etched.step / el357c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); el357c.step / el357c.glb are the bare package body.
