APX803S-26SR-7

Diodes Incorporated · Monitors & Reset Circuits · SOT-23

APX803S-26SR-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 open-drain reset output that asserts when VCC falls below the reset threshold and is guaranteed to be a logic low for VCC above 1V.
2 GND power_in Ground reference pin for the device.
3 VCC power_in Operating voltage input, with a recommended supply range of 1.0 V to 5.5 V.

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

  • Symbol: APX803S-26SR-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: apx803s-26sr-7-etched.step / apx803s-26sr-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); apx803s-26sr-7.step / apx803s-26sr-7.glb are the bare package body.
