Insulated MOSFET gate; VGS absolute max ±20 V. Gate threshold voltage VGS(th) typ. 2 V (1 V min, 3 V max at VDS = VGS, ID = 250 µA). Total gate charge Qg typ. 47 nC at VDS = 30 V, VGS = 10 V, ID = 50 A. |+| 2 | D | passive | Drain. N-channel MOSFET drain; VDS breakdown 60 V min. Continuous ID = 58 A at TC = 25 °C (package limited), RDS(on) = 10 mΩ typ at VGS = 10 V, ID = 20 A. Also connected to the exposed tab (heat slug) of the TO-252AA package. |+| 3 | S | passive | Source. N-channel MOSFET source; continuous source (body diode) current IS = 50 A max. Body diode VSD typ. 1 V (max 1.5 V) at IF = 20 A, VGS = 0 V; trr typ. 45 ns. |+| 4 | D (Tab) | passive | Exposed thermal tab, internally connected to the Drain (pin 2). Used as the primary heat-sinking path; RthJC = 0.85 °C/W typ. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | TO-252 |+| Category | Transistors/Thyristors |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `AUIRFR4105ZTRPBF-VB`++## CAD (KiCad official)++- Symbol: `AUIRFR4105ZTRPBF-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/8603384632662773760) (None pp, sha256 `6a30dc44eda5d13c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
