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 terminal controlling the drain-to-source channel. VGS(th) = 2.0-4.0 V, absolute maximum VGS = ±20 V. Drive with VGS = 10 V for rated RDS(on) = 0.660 Ω. |+| 2 | D | passive | Drain. High-voltage power terminal, VDS = 500 V max, continuous ID = 13 A at TC = 25 °C (8.1 A at TC = 100 °C), pulsed IDM = 50 A. Electrically connected to the TO-220AB mounting tab. |+| 3 | S | passive | Source. Low-side power terminal and anode of the integral body diode (VSD ≤ 1.5 V at IS = 14 A). Reference for VGS and VDS. |+| TAB | D | passive | Mounting tab, internally connected to the Drain. Provides the primary thermal path (RthJC = 0.50 °C/W max) and is at drain potential - isolate from grounded heatsinks. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | TO-220AB |+| Category | Transistors/Thyristors |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `IRF840LCPBF-VB`++## CAD (KiCad official)++- Symbol: `IRF840LCPBF-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/8603121662909173760) (None pp, sha256 `5a220b5292951f9a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
