Changjing · Bridge Rectifiers · GBU
GBU1008 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 of the bridge, marked + on the package drawing at the left-most lead; rated IO 10A with heatsink (Tc=80°C), 3.0A without heatsink (Ta=25°C). |
| 2 | AC1 | passive | AC input of the bridge (second lead from the + end); VRRM 1000V for GBU1010, 800V for GBU1008, VRMS 560V for the GBU1008 grade. |
| 3 | AC2 | passive | AC input of the bridge (third lead, next to the - lead); VRRM 800V and VRMS 560V for the GBU1008 grade, peak surge IFSM 220A (60Hz, 1 cycle). |
| 4 | - | passive | Negative DC output of the bridge, marked - on the package drawing at the right-most lead; peak forward voltage 1.0V max per diode at IFM=5A. |
