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 MOS gate that controls channel conduction between Drain and Source. Drive with VGS ≤ ±20 V; threshold VGS(th) typically 2-4 V. |+| 2 | D | passive | Drain. Main power terminal; internally bonded to the exposed metal tab of the DPAK package for heatsinking. VDSS ≈ 100 V, continuous ID ≈ 33 A. |+| 3 | S | passive | Source. Return terminal for drain current; reference for VGS. Also the anode of the intrinsic body diode (cathode = Drain). |+| 4 | D (TAB) | passive | Exposed thermal tab, electrically identical to the Drain (pin 2). Solder to a copper pour for thermal 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.++- `IRFR3910TRLPBF-VB`++## CAD (KiCad official)++- Symbol: `IRFR3910TRLPBF-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/8602989542429642752) (None pp, sha256 `b3835c0dcbb6ee5a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
