Changjing · Bridge Rectifiers · GBU
GBU2008 from Changjing, in a GBU. 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 terminal of the bridge rectifier, marked + on the package outline (leftmost lead). |
| 2 | AC1 | passive | AC input terminal of the single-phase bridge (second lead from the + end); the drawing does not label it. |
| 3 | AC2 | passive | AC input terminal of the single-phase bridge (third lead, next to the - end); the drawing does not label it. |
| 4 | - | passive | Negative DC output terminal of the bridge rectifier, marked - on the package outline (rightmost lead). |
