MBR3045CS from YFW, 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 leg (15 A per leg average forward current, 45 V maximum repetitive peak reverse voltage). |
| 2 | K | passive | Common cathode of both Schottky legs, also connected to the mounting tab (45 V maximum DC blocking voltage, 30 A total average forward current). |
| 3 | A2 | passive | Anode of the second Schottky diode leg (15 A per leg average forward current, 45 V maximum repetitive peak reverse voltage). |
