# APX810S00-29SR-7

**Diodes Incorporated** · Monitors & Reset Circuits · SOT-23

APX810S00-29SR-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-high push-pull reset output (APX810S), asserted when VCC falls below the reset threshold and held for the reset timeout period after VCC rises above it; pin 1 on the SR package. |
| 2 | GND | power_in | Ground. |
| 3 | VCC | power_in | Operating voltage input, 1.0V to 5.5V recommended, absolute maximum -0.3V to 6.0V. |

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

- Symbol: `APX810S00-29SR-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: `apx810s00-29sr-7-etched.step` / `apx810s00-29sr-7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `apx810s00-29sr-7.step` / `apx810s00-29sr-7.glb` are the bare package body.
