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 | G | input | Gate terminal of the N-channel MOSFET. Controls channel conduction between Drain and Source. VGS(th) = 1.0 V to 3.0 V; VGS absolute maximum = ± 20 V. |+| 2 | D | passive | Drain terminal of the N-channel MOSFET. Electrically connected to the exposed metal tab of the TO-252 package. VDS max = 60 V; continuous ID = 18 A at TC = 25 °C. |+| 3 | S | passive | Source terminal of the N-channel MOSFET. Reference for VGS and VDS. Body diode anode is internally tied to Source (VSD = 0.8 V typ. at IF = 5.2 A). |+| 4 | D | passive | Drain tab (exposed thermal pad on TO-252). Electrically the Drain node - same net as pin 2. Serves as the primary thermal path (RthJC = 3 °C/W) and must be soldered to a copper pour for rated dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | TO-252 |+| Category | Transistors/Thyristors |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `AOD444-VB`++## CAD (KiCad official)++- Symbol: `AOD444-VB`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [VBsemi Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8609096306619543552) (8 pp, sha256 `2ae704b0d25461f2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
