GBU2504 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 outline, with a rated average rectified output of 25A (with heatsink, Tc=98°C). |
| 2 | AC1 | passive | AC input terminal (inner lead); for GBU2504 VRRM is 400V and maximum RMS voltage is 280V. |
| 3 | AC2 | passive | AC input terminal (inner lead); for GBU2504 VRRM is 400V and maximum RMS voltage is 280V. |
| 4 | - | passive | Negative DC output terminal, marked − on the package outline, with a surge forward current (IFSM) rating of 350A (60Hz sine, 1 cycle). |
