Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD | power_in | Power supply input. Operating range 3.0V to 27V (absolute max 40V transient, load-dump up to 40V). Reverse supply rated to -18V. Recommended 10nF-100nF decoupling capacitor (CIN) to GND. Typical supply current IDD ≈ 2.8mA (max 4.8mA over temp). |+| 2 | GND | power_in | Ground reference for the device. Return for VDD, output current, and internal Hall-sensor bias circuits. |+| 3 | OUTPUT | output | Open-drain latch output (AH3712 variant; AH3712A includes internal ~14kΩ pull-up, AH3712B is inverted). Requires external pull-up resistor RL to VDD. VOUT_ON ≈ 0.25V typ (max 0.42V) at 20mA sink; output leakage <0.1µA typ at 27V off. Sinks up to 60mA absolute max with internal current limit IOCL of 30-60mA. Rated to 40V off-state; 36V zener clamp. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23-3 |+| Category | Magnetic Sensors |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AH3712-SA-7`+- `AH3712-SA-7W-7`+- `AH3712-SA-7P-B`++## CAD (KiCad official)++- Symbol: `AH3712-SA-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8604309783683866624) (None pp, sha256 `5fa3d3302b2575c3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
