# STW7N95K3

**STMicroelectronics** · MOSFETs · TO-247-3

STW7N95K3 from STMicroelectronics, in a TO-247-3. 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; controls the MOSFET, with built-in back-to-back Zener protection to source (BVGSO 30 V min at Igs = ±1 mA, VGS absolute max ±30 V). |
| 2 | D | passive | Drain; V(BR)DSS 950 V min, continuous drain current 7.2 A at TC = 25 °C, pulsed 28.8 A. |
| 3 | S | passive | Source; connected to the body diode anode and the Zener-protected gate return, source-drain current 7.2 A. |

## CAD (KiCad official)

- Symbol: `STW7N95K3`
- Footprint: `Package_TO_SOT_THT:TO-247-3_Vertical`
- 3D model: TO-247-3 (KiCad packages3D, STEP)
- 3D model files: `stw7n95k3-etched.step` / `stw7n95k3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stw7n95k3.step` / `stw7n95k3.glb` are the bare package body.
