EL3H7

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

EL3H7 from Everlight Elec, in a SSOP-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 Infrared emitting diode anode; the datasheet gives a forward current limit of 50 mA (IF), a peak forward current of 1 A (1 µs pulse), and a reverse voltage of 6 V, and states the device is not designed for reverse operation.
2 Cathode passive Infrared emitting diode cathode; the datasheet states the device is not designed for reverse operation, with reverse voltage (VR) of 6 V rated only for the reverse-current test condition.
3 Emitter passive Phototransistor emitter; the emitter-collector voltage is rated at 7 V (VECO) with a minimum emitter-collector breakdown voltage of 7 V at IE = 0.1 mA.
4 Collector passive Phototransistor collector; the collector-emitter voltage is rated at 80 V (VCEO) and the collector current at 50 mA (IC).

CAD (KiCad official)

  • Symbol: EL3H7
  • Footprint: Package_SO:SSOP-4_4.4x2.6mm_P1.27mm
  • 3D model: SSOP-4, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: el3h7-etched.step / el3h7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); el3h7.step / el3h7.glb are the bare package body.
