GBU25M from LGE, 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 | DC negative output of the bridge, marked "-" on the leftmost lead of the package drawing. |
| 2 | AC1 | passive | AC input terminal, marked "AC" on the package drawing; the bridge is rated for 1000 V VRRM and 700 V VRMS (GBU25M). |
| 3 | AC2 | passive | Second AC input terminal, marked "AC" on the package drawing; the bridge is rated for 25 A average forward output current at TC=100°C. |
| 4 | + | passive | DC positive output of the bridge, marked "+" on the rightmost lead of the package drawing. |
