AP55N03K

ALLPOWER ShenZhen Quan Li Semiconductor · MOSFETs · TO-252

AP55N03K from ALLPOWER ShenZhen Quan Li Semiconductor, 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; gate-source voltage limit is ±12 V, with threshold VGS(th) 1 V min, 1.3 V typ, 2 V max at VDS=VGS, ID=250 µA.
2 D passive Drain; rated 30 V drain-source with 30 A continuous (22 A at TC=100°C) and 90 A pulsed drain current.
3 S passive Source; connects to the body diode anode, with a 30 A maximum diode forward current.

CAD (KiCad official)

  • Symbol: AP55N03K
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: ap55n03k-etched.step / ap55n03k-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap55n03k.step / ap55n03k.glb are the bare package body.
