MBR1040CT 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 (per-diode 5 A average forward current, 40 V VRRM for MBR1040CT, VF 0.70 V at 5 A). |
| 2 | K | passive | Common cathode of both diodes, also connected to the mounting tab (per-device 10 A average forward current, 40 V maximum DC blocking voltage). |
| 3 | A2 | passive | Anode of diode 2 (per-diode 5 A average forward current, 40 V VRRM for MBR1040CT, VF 0.70 V at 5 A). |
