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 | Positive supply input, 1.65 V to 5 V operating (6 V absolute max). A 100 Ω series resistor is recommended for reverse-polarity protection; typical bypass is a 10 nF capacitor (C1) to GND per the application circuit. |+| 2 | Output | output | Totem-pole (push-pull) CMOS Hall switch output. Drives low when an operating-point magnetic flux (|B| > BOP, either N or S pole) is detected and high otherwise (omni-polar). VOH ≥ VDD-0.2 V and VOL ≤ 0.2 V at IOUT = 0.5 mA; IOUT absolute max 1 mA. Application circuit shows a 100 pF capacitor (C2) to GND on this pin. |+| 3 | GND | power_in | Ground / negative supply return for the device. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | WILLSEMI Will Semicon |+| Package | TSOT-23-3L |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `WH251E-3/TR`++## CAD (KiCad official)++- Symbol: `WH251E-3`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: TSOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [WILLSEMI Will Semicon datasheet](docs/wh251e-3-datasheet.pdf) (12 pp, sha256 `56fdee8ddbf6b1a5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
