GBU15005 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 (leftmost lead, marked + on the package drawing); rectified output up to 15A average with heatsink at Tc=100°C. |
| 2 | AC1 | passive | AC input terminal (second lead from the + side); VRRM 50V to 1000V depending on grade, 240A non-repetitive surge (IFSM). |
| 3 | AC2 | passive | AC input terminal (third lead from the + side); VRRM 50V to 1000V depending on grade, 240A non-repetitive surge (IFSM). |
| 4 | - | passive | Negative DC output of the bridge (rightmost lead, marked − on the package drawing), return for the rectified output. |
