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.
