GBU1508G

NH · Bridge Rectifiers · GBU

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.
