# 2SK2158

**Shikues** · MOSFETs · SOT-23

2SK2158 from Shikues, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Gate | input | Gate terminal; gate-source voltage limit is ±20 V and threshold VGS(th) is 0.5 V min to 1.5 V max at VGS=VDS, ID=1.0 mA. |
| 2 | Source | passive | Source terminal; drain-source diode forward voltage VSD is 2.5 V max at VGS=0 V, IS=0.2 A. |
| 3 | Drain | passive | Drain terminal; drain-source voltage is rated 50 V with continuous drain current of 0.2 A and RDS(ON) of 3.5 Ω max at VGS=5 V, ID=0.2 A. |

## CAD (KiCad official)

- Symbol: `2SK2158`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `2sk2158-etched.step` / `2sk2158-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2sk2158.step` / `2sk2158.glb` are the bare package body.
