MBR40100CT from Shandong Jingdao Microelectronics, in a TO-220AB. 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 diode 1 (first leg); each leg is rated 20 A average forward current, 100 V repetitive peak reverse voltage, and 0.85 V max forward voltage at 20 A. |
| 2 | K | passive | Common cathode of both diodes, which is also the metal tab; the device is rated 40 A total average forward current and 100 V DC blocking voltage. |
| 3 | A2 | passive | Anode of diode 2 (second leg); each leg is rated 20 A average forward current, 100 V repetitive peak reverse voltage, and 0.85 V max forward voltage at 20 A. |
