KBU1008 from Yangzhou Yangjie Elec Tech, 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 | Negative DC output terminal of the bridge, marked "-" on the body above the first lead. |
| 2 | AC | passive | AC input terminal, marked "AC" on the body; the two inner leads are the AC inputs, rated for VRRM 800 V (KBU1008). |
| 3 | AC | passive | Second AC input terminal, marked "AC" on the body; the two inner leads are the AC inputs, rated for VRRM 800 V (KBU1008). |
| 4 | + | passive | Positive DC output terminal of the bridge, marked "+" on the body above the fourth lead; average rectified output current is 10 A at Tc=115 °C. |
