GBU402 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; the package is rated for 4 A average rectified output with heatsink (Tc=100℃) and 2.4 A without heatsink (Ta=100℃). |
| 2 | 2 | passive | AC input terminal; the GBU402 is rated for 200 V VRRM and 140 V maximum RMS voltage. |
| 3 | 3 | passive | Second AC input terminal; the GBU402 is rated for 200 V VRRM and 140 V maximum RMS voltage. |
| 4 | - | passive | Negative DC output of the bridge, which is the return side of the rectified output; the terminals are rated for 2 kV AC for 1 minute to the case. |
