# TX40N06B

**XDS** · MOSFETs · TO-252

TX40N06B from XDS, 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. |
| 2 | D | passive | Drain terminal of the N-channel MOSFET; drain-source voltage is rated at 60 V and continuous drain current at 35 A (TC = 25 °C). |
| 3 | S | passive | Source terminal of the N-channel MOSFET; continuous source-drain diode current is rated at 10 A (TC = 25 °C, per note e). |

## CAD (KiCad official)

- Symbol: `TX40N06B`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `tx40n06b-etched.step` / `tx40n06b-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tx40n06b.step` / `tx40n06b.glb` are the bare package body.
