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 | REF | input | Reference input to the internal error amplifier. Regulation forces this pin to VREF (nominally 2.495V) relative to ANODE. Reference input current is typically 0.7uA (4uA max); maximum allowed IREF is 10mA. |+| 2 | CATHODE | passive | Shunt cathode (K). Sinks current when the REF pin exceeds VREF, clamping VKA. Operating VKA range is VREF to 36V, cathode current 0.5mA to 100mA (Absolute Max VKA = 40V, IKA = -100 to 150mA). Dynamic impedance ZKA = 0.15 Ohm typ. |+| 3 | ANODE | passive | Shunt anode (A), the device's local ground reference. All VREF and VKA voltages are referenced to this pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AS431HANTR-G1`+- `AS431HBNTR-G1`+- `AS431HMANTR-G1`+- `AS431HMBNTR-G1`+- `AS431HAZTR-G1`+- `AS431HBZTR-G1`++## CAD (KiCad official)++- Symbol: `AS431HANTR-G1`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/as431hantr-g1-datasheet.pdf) (15 pp, sha256 `53df2842f0c152f0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
