KBU1510 from MDD Microdiode Semiconductor, in a KBU. 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 | + | passive | Positive DC output of the bridge, marked + in the pin-numbering symbol; the bridge is rated 15 A average output at TC=50°C. |
| 2 | AC1 | passive | AC input terminal (~) of the bridge; VRMS is 700 V maximum for KBU1510. |
| 3 | AC2 | passive | AC input terminal (~) of the bridge; VRMS is 700 V maximum for KBU1510. |
| 4 | - | passive | Negative DC output of the bridge, marked − in the pin-numbering symbol; VRRM is 1000 V for KBU1510. |
