# MBR3045PT

**JUXING** · Schottky Diodes · TO-247

MBR3045PT from JUXING, in a TO-247. 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 leg (PIN 1 in the schematic symbol), rated 45 V VRRM and 15 A average forward current per leg. |
| 2 | K | passive | Common cathode of both Schottky diode legs (PIN 2 in the schematic symbol), rated 45 V DC blocking voltage and 30 A total average forward current. |
| 3 | A2 | passive | Anode of the second Schottky diode leg (PIN 3 in the schematic symbol), rated 45 V VRRM and 15 A average forward current per leg. |

## CAD (KiCad official)

- Symbol: `MBR3045PT`
- Footprint: `Package_TO_SOT_THT:TO-247-3_Vertical`
- 3D model: TO-247 (KiCad packages3D, STEP)
- 3D model files: `mbr3045pt-etched.step` / `mbr3045pt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mbr3045pt.step` / `mbr3045pt.glb` are the bare package body.
