GBU8J-BP from MCC Micro Commercial Components, 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, the leftmost lead marked "-" in the package drawing; GBU8J is rated 600V peak reverse and 8.0A average forward current at TC=100°C. |
| 2 | 2 | passive | AC input lead marked "~" in the package drawing; GBU8J is rated 420V maximum RMS voltage. |
| 3 | 3 | passive | Second AC input lead marked "~" in the package drawing; GBU8J is rated 420V maximum RMS voltage. |
| 4 | + | passive | DC positive output of the bridge, the rightmost lead marked "+" in the package drawing; GBU8J is rated 600V maximum DC blocking voltage. |
