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. Logic-level MOSFET control input; VGS(th) typ 1.5 V (1 V min, 2 V max at ID = 1 mA, Tj = 25 °C). Absolute maximum VGS = ±10 V DC (pulsed VGSM = ±15 V, tp ≤ 50 µs). Input capacitance Ciss typ 2190 pF. |+| 2 | D | passive | Drain. MOSFET drain terminal; VDS max 55 V, ID max 55 A (Tmb = 25 °C, VGS = 5 V), peak IDM 219 A (tp ≤ 10 µs). Electrically connected to the mounting base (mb) tab. |+| 3 | S | passive | Source. MOSFET source terminal; body-diode source current IS max 55 A, peak ISM 219 A (tp ≤ 10 µs). Serves as the reference for VGS and VDS. |+| mb | D | passive | Mounting base (exposed tab). Internally connected to the drain; acts as the primary thermal path (Rth(j-mb) max 1.3 K/W). Solder to a copper pad on the drain net for heat dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | DPAK |+| Category | Transistors/Thyristors |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `BUK9219-55A`++## CAD (KiCad official)++- Symbol: `BUK9219-55A`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: DPAK (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588885391117705216) (14 pp, sha256 `f6a9386c415dd569`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
