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 gate control input. VGS(th) 1.0-2.5 V; maximum gate-source voltage ±20 V. RDS(on) = 24 mΩ at VGS=10 V, 28 mΩ at VGS=4.5 V. |+| 2 | D | passive | Drain. MOSFET drain terminal, VDS(max) = 60 V, continuous drain current up to 50 A at TC=25 °C (36 A at TC=100 °C), pulsed ID = 200 A. Internally connected to the tab. |+| 3 | S | passive | Source. MOSFET source terminal; body diode anode. Continuous source-drain diode current 50 A, body diode voltage VSD ≤ 2.5 V at IS=51 A. |+| 4 | D | passive | Drain (heatsink tab). Metal tab electrically connected to the drain; used for thermal dissipation with RthJC = 1.0 °C/W. Often soldered or bolted to a heatsink. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | TO-220AB |+| Category | Transistors/Thyristors |+| Pins | 4 |++## CAD (KiCad official)++- Symbol: `BUK9575-55A-VB`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220AB (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [VBsemi Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8603101040728154112) (None pp, sha256 `fd679eb4426aa4c3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
