GBU1508G from NH, 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 | Cathode(-) | power_out | Output cathode (-) DC terminal of the bridge rectifier, marked "-" on the case. |
| 2 | AC1 | input | AC input pin 1 of the bridge rectifier, one of the two AC supply connections. |
| 3 | AC2 | input | AC input pin 2 of the bridge rectifier, the second of the two AC supply connections. |
| 4 | Anode(+) | power_out | Output anode (+) DC terminal of the bridge rectifier, marked "+" on the case. |
