AP2331SA-7

Diodes Incorporated · AC-DC Controllers and Regulators · SOT-23-3

AP2331SA-7 from Diodes Incorporated, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the device. Connect to system ground; a 0.1µF input bypass capacitor from IN to GND is recommended.
2 OUT power_out Switch output pin. Delivers the switched, current-limited (0.4A typ ILIMIT) power to the load; recommended 0.1µF output capacitor to GND. Absolute maximum VOUT = VIN + 0.3V.
3 IN power_in Voltage input pin. Supply input, 2.7V to 5.2V recommended (absolute max 6.5V). Bypass to GND with a 0.1µF ceramic capacitor.

CAD (KiCad official)

  • Symbol: AP2331SA-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: ap2331sa-7-etched.step / ap2331sa-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap2331sa-7.step / ap2331sa-7.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2331sa-7.step 59 KB You want the bare part, or you mark your own boards.
ap2331sa-7-etched.step 1.7 MB You want the part with AP2331SA-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 426 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (12 pp, sha256 b16ba35238747d20, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
