AP4438

ALLPOWER ShenZhen Quan Li Semiconductor · MOSFETs · SOT-89

AP4438 from ALLPOWER ShenZhen Quan Li Semiconductor, in a SOT-89. 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 limited to ±12 V absolute maximum, with VGS(th) of 1 V min to 3 V max at ID=250uA.
2 D passive Drain; drain-source voltage rated 30 V, continuous drain current 11.8 A at TA=25°C and 40 A pulsed.
3 S passive Source; connects to the source of the N-channel MOSFET, with a body diode forward voltage of 1.2 V max at IS=2.1 A.

CAD (KiCad official)

  • Symbol: AP4438
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: ap4438-etched.step / ap4438-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap4438.step / ap4438.glb are the bare package body.
