ASDM540G-R

Ascend · MOSFETs · TO-263

ASDM540G-R from Ascend, in a TO-263. 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 control input with a maximum gate-source voltage of ±20 V and a threshold of 1 V min to 2.4 V max at 250 µA.
2 D passive Drain terminal rated for 100 V drain-source voltage and 33 A continuous drain current.
3 S passive Source terminal, the return path for the 33 A continuous drain current.

CAD (KiCad official)

  • Symbol: ASDM540G-R
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263 (KiCad packages3D, STEP)
  • 3D model files: asdm540g-r-etched.step / asdm540g-r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); asdm540g-r.step / asdm540g-r.glb are the bare package body.
