# 2SK3669-VB

**VBsemi Elec** · MOSFETs · TO-252

2SK3669-VB from VBsemi Elec, in a TO-252. 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 terminal of the N-channel MOSFET; gate-source voltage is rated at ±20 V (VGS). |
| 2 | D | passive | Drain terminal; drain-source voltage is rated at 100 V (VDS) with continuous drain current ID limited by TC and TJ per the absolute maximum ratings. |
| 3 | S | passive | Source terminal; continuous source current (diode conduction) is rated at IS = 3 A. |

## CAD (KiCad official)

- Symbol: `2SK3669-VB`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `2sk3669-vb-etched.step` / `2sk3669-vb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2sk3669-vb.step` / `2sk3669-vb.glb` are the bare package body.
