# SK335N

**Shikues** · MOSFETs · SOT-23

SK335N 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 | G | input | Gate; the datasheet gives VGS max ±8 V, gate threshold 0.4 V to 1.3 V at VGS=VDS, ID=250µA, and gate leakage of ±100 nA max. |
| 2 | S | passive | Source; the datasheet lists the maximum continuous drain current as 2.0 A, and the body diode forward voltage as 1.2 V max at IS=0.94A. |
| 3 | D | passive | Drain; the datasheet gives a maximum drain-source voltage of 20 V and RDS(ON) of 80 mΩ max at VGS=4.5 V (90 mΩ max at 2.5 V). |

## CAD (KiCad official)

- Symbol: `SK335N`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `sk335n-etched.step` / `sk335n-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sk335n.step` / `sk335n.glb` are the bare package body.
