# MDD50N06D

**MDD Microdiode Semiconductor** · MOSFETs · TO-252

MDD50N06D from MDD Microdiode Semiconductor, 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 | Gate | input | Gate terminal of the MOSFET; the datasheet gives the gate-source voltage limit as VGS ±20 V. |
| 2 | Drain | passive | Drain terminal of the MOSFET; the datasheet gives a drain-source voltage of 60 V and a continuous drain current of 50 A. |
| 3 | Source | passive | Source terminal of the MOSFET; the datasheet gives a source (body diode) drain current ISD of 50 A. |

## CAD (KiCad official)

- Symbol: `MDD50N06D`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `mdd50n06d-etched.step` / `mdd50n06d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mdd50n06d.step` / `mdd50n06d.glb` are the bare package body.
