ESD4186

ElecSuper · MOSFETs · TO-252

ESD4186 from ElecSuper, in a TO-252. 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 Gate input Gate terminal of the N-channel MOSFET, with VGS limited to ±20 V and gate threshold VGS(TH) of 1.0 to 1.8 V.
2 Drain passive Drain terminal of the N-channel MOSFET, rated 45 V BVDSS with 36 A continuous drain current at TC=25°C.
3 Source passive Source terminal of the N-channel MOSFET, serving as the reference for the gate-source voltage VGS rated ±20 V.

CAD (KiCad official)

  • Symbol: ESD4186
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: esd4186-etched.step / esd4186-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd4186.step / esd4186.glb are the bare package body.
