APX803-46SRG-7

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

APX803-46SRG-7 from Diodes Incorporated, in a SOT-23R. 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 open-drain reset output, asserted when VCC falls below the reset threshold and held low for the reset timeout period (140ms min) after VCC rises above it; guaranteed low for VCC > 1V, rated -0.3 to 6V.
2 GND power_in Ground.
3 VCC power_in Operating voltage input, 1.1V to 5.5V recommended (absolute maximum -0.3 to +6.0V), monitored against the 4.63V typical reset threshold of the APX803-46.

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

  • Symbol: APX803-46SRG-7
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23R, 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: apx803-46srg-7-etched.step / apx803-46srg-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); apx803-46srg-7.step / apx803-46srg-7.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (11 pp, sha256 49f1f0449cde1d5a, 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).
