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. Insulated-gate control terminal for the N-channel MOSFET. Absolute maximum VGS = ±20 V; VGS(th) = 2.0-4.0 V at VDS = VGS, ID = 250 μA. |+| 2 | S | passive | Source. Reference terminal for gate drive and current return for the N-channel channel. Also the anode of the intrinsic body diode. |+| 3 | D | passive | Drain. Power terminal for the N-channel MOSFET; VDS(max) = 200 V, continuous ID = 1.0 A at TC = 25 °C, RDS(on) = 1.2 Ω typ at VGS = 10 V. Cathode of the intrinsic body diode. |+| 4 | D | passive | Drain (tab). Large heat-spreading tab on SOT-223 electrically tied to the drain; used as the primary thermal path to the PCB copper pour. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | SOT-223 |+| Category | Transistors/Thyristors |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `STN4NF20L-VB`++## CAD (KiCad official)++- Symbol: `STN4NF20L-VB`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [VBsemi Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8602998055642296320) (None pp, sha256 `299f417520f37136`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
