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 | A | passive | Anode of the SiC Schottky diode. Connect to the positive terminal of the reverse-biased circuit; conducts forward current up to IF = 18 A (TC = 25 °C). |+| 2 | K | passive | Cathode of the SiC Schottky diode. Electrically common with the exposed metal tab/CASE. Rated VRRM = 1200 V. |+| TAB | K/CASE | passive | Exposed metal tab / CASE, electrically the cathode. Also serves as the primary thermal path (RthJC = 1.55 °C/W). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HXY MOSFET |+| Package | TO-252-2L |+| Category | Silicon Carbide (SiC) Devices |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `HC3D05120E`++## CAD (KiCad official)++- Symbol: `HC3D05120E`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HXY MOSFET datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8603011182702325760) (6 pp, sha256 `7ce14c5543467849`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
