# MBRD2045

**GOODWORK** · Schottky Diodes · TO-252

MBRD2045 from GOODWORK, 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 | A1 | passive | Anode of the first Schottky diode (left pin in the package diagram), with the common cathode at the heat-sink tab; part is rated 45 V VRRM and 20 A average forward current in total. |
| 2 | K | passive | Common cathode, connected to the bottom-side heat sink tab, which is the center position (pin 2) in the package drawing. |
| 3 | A2 | passive | Anode of the second Schottky diode (right pin in the package diagram), with the common cathode at the heat-sink tab; part is rated 45 V VRRM and 20 A average forward current in total. |

## CAD (KiCad official)

- Symbol: `MBRD2045`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `mbrd2045-etched.step` / `mbrd2045-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mbrd2045.step` / `mbrd2045.glb` are the bare package body.
