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 of the N-channel MOSFET; VGS(th) = 1.0 to 3.0 V, VGS(max) = ±20 V. Drives the channel between drain and source. |+| 2 | D | passive | Drain. Power drain terminal of the N-channel MOSFET; VDS(max) = 60 V, ID = 18 A continuous at TC = 25 °C. Electrically connected to the TO-252 tab (heat slug). |+| 3 | S | passive | Source. Power source terminal of the N-channel MOSFET; carries the drain current returned to the circuit reference. Body diode anode is internally tied to source (VSD ≈ 0.8 V typ at IF = 5.2 A). |+| 4 | D | passive | Drain (exposed tab / heat slug). Electrically identical to pin 2; provides the primary thermal path (RthJC = 3 °C/W) for soldering to a PCB copper pour. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | TO-252 |+| Category | Transistors/Thyristors |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `2SK2503-VB`++## CAD (KiCad official)++- Symbol: `2SK2503-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/8603048171308806144) (None pp, sha256 `7b8d6207336b4f54`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
