# MBRD1045CT

**LGE** · Schottky Diodes · TO-252

MBRD1045CT from LGE, 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 (common-cathode dual), rated 45 V VRRM and 5 A average forward current per diode. |
| 2 | K | passive | Common cathode of both Schottky diodes, also connected to the tab, with 45 V peak inverse voltage and 2×5 A total average rectified current. |
| 3 | A2 | passive | Anode of the second Schottky diode (common-cathode dual), rated 45 V VRRM and 5 A average forward current per diode. |
