Vishay Intertech · Bridge Rectifiers · GBU
GBU8J-E3 from Vishay Intertech, 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 | Negative DC output terminal of the bridge, the lead at the end opposite the beveled corner, as marked on the body. |
| 2 | 2 | passive | AC input terminal, the first of the two middle leads in the in-line arrangement. |
| 3 | 3 | passive | AC input terminal, the second of the two middle leads in the in-line arrangement. |
| 4 | + | passive | Positive DC output terminal of the bridge, the lead by the beveled corner, rated for 8.0 A average forward current (IF(AV) at TC = 60 °C). |
