Changjing · Bridge Rectifiers · GBU
GBU804 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, marked + on the package drawing, at the leftmost lead; the bridge is rated 8 A average output (Tc=110°C with heatsink) and VRRM up to 1000V depending on grade. |
| 2 | AC1 | passive | AC input terminal at the second lead position, unmarked on the drawing; the bridge is rated VRMS 35V to 700V depending on grade. |
| 3 | AC2 | passive | AC input terminal at the third lead position, unmarked on the drawing; the bridge is rated VRMS 35V to 700V depending on grade. |
| 4 | - | passive | Negative DC output terminal, marked − on the package drawing, at the rightmost lead; the bridge is rated 8 A average output (Tc=110°C with heatsink) and VRRM up to 1000V depending on grade. |
