APX809S00-40SR-7

Diodes Incorporated · Monitors & Reset Circuits · SOT-23

APX809S00-40SR-7 from Diodes Incorporated, in a SOT-23. 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 /RESET output Active-low push-pull reset output (APX809S); it asserts when VCC falls below the preset reset threshold and stays asserted for the reset active timeout period after VCC rises above the threshold (1.7 ms typical for the -00 timeout option in this part number).
2 GND power_in Ground reference pin.
3 VCC power_in Operating voltage input; the recommended supply range is 1.0 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: APX809S00-40SR-7
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, 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: apx809s00-40sr-7-etched.step / apx809s00-40sr-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); apx809s00-40sr-7.step / apx809s00-40sr-7.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (10 pp, sha256 b644892b2c8d0948, 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).
