GBU8M from LRC, 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 of the bridge, leftmost lead in the circuit diagram. |
| 2 | 2 | passive | AC input terminal; the datasheet rates the bridge at VRM 1000 V for GBU8M. |
| 3 | 3 | passive | AC input terminal; the datasheet rates the bridge at 8 A average forward current with heatsink at Tc=100°C. |
| 4 | - | passive | Negative DC output terminal of the bridge, rightmost lead in the circuit diagram. |
