20N03

HL · MOSFETs · TO-252

20N03 from HL, 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 G input Gate of the MOSFET; the datasheet rates gate-source voltage VGS at ±20 V, and VGS(th) is 1 to 2.5 V at VGS=VDS, ID=250µA.
2 D passive Drain of the MOSFET; the datasheet rates drain-source voltage VDS at 30 V and continuous drain current ID at 20 A (TC=25℃).
3 S passive Source of the MOSFET; the datasheet gives continuous source current IS as 9 A maximum.

CAD (KiCad official)

  • Symbol: 20N03
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: 20n03-etched.step / 20n03-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 20n03.step / 20n03.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
