Changjing · Bridge Rectifiers · KBU
KBU802 from Changjing, 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 | + | power_out | Positive DC output of the bridge, with average rectified output current of 8A (Tc=100°C) and VRRM of 50V to 1000V depending on grade. |
| 2 | 2 | passive | AC input terminal of the single-phase bridge, with surge forward current IFSM of 200A (60Hz sine, 1 cycle, Tj=25°C). |
| 3 | 3 | passive | Second AC input terminal of the single-phase bridge, with surge forward current IFSM of 200A (60Hz sine, 1 cycle, Tj=25°C). |
| 4 | - | power_in | Negative DC output (return) terminal of the bridge, with average rectified output current of 8A (Tc=100°C). |
