APX803L20-32SA-7

Diodes Incorporated · Supervisor And Reset ICs · SOT-23-3

APX803L20-32SA-7 from Diodes Incorporated, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 GND power_in Ground reference pin for the supervisor.
2 RESET output Open-drain active-low reset output; the datasheet gives a recommended output voltage range of 0 V to 5.5 V and VOL of 0.4 V max at VCC = VTH - 0.2 V and ISINK = 3.5 mA.
3 VCC power_in Operating voltage input; the recommended supply range is 0.9 V to 5.5 V and the absolute maximum rating is -0.3 V to 6.0 V.

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: APX803L20-32SA-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: apx803l20-32sa-7-etched.step / apx803l20-32sa-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); apx803l20-32sa-7.step / apx803l20-32sa-7.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (22 pp, sha256 849cd25d6fd15081, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
