Insulated MOSFET control terminal. Absolute maximum VGS = ±20 V; typical VGS(th) = 1.2 V to 2.5 V (VDS = VGS, ID = 250 µA). Gate resistance Rg ≈ 0.85 Ω typ. |+| 2 | D | passive | Drain. N-channel MOSFET drain, also electrically connected to the metal tab. Absolute maximum VDS = 40 V; continuous ID = 110 A at TC = 25 °C; pulsed IDM = 270 A. |+| 3 | S | passive | Source. N-channel MOSFET source. Body diode from Source to Drain (VSD ≈ 0.8 V typ. at IS = 20 A, IS = 110 A continuous at TC = 25 °C). |+| TAB | D | passive | Heatsink tab, internally connected to the Drain. Used for thermal dissipation (RthJC = 0.33 °C/W typ.). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | TO-220AB |+| Category | Transistors/Thyristors |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `IRF4104PBF-VB`++## CAD (KiCad official)++- Symbol: `IRF4104PBF-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/8603043825015812096) (None pp, sha256 `115af3893e73b834`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
