GBU1504 – 400V 15A Single-Phase Bridge Rectifier in GBU Package | 400V 15A Bridge

GBU1504 is a 400V, 15A single-phase full-wave bridge rectifier module optimized for offline mains rectification (230/277 VAC) and DC-bus charging. The internal core ensures 1.0V conduction drop at 100 °C, providing low rectification power loss and thermal reliability. It withstands 240A IFSM surge peaks, vital for reservoir capacitive charging and transformer magnetizing inrush tolerance. 7.5µA max IR leakage ensures long-term DC blocking stability. GBU epoxy block enables robust thermal path, secure PCB leads, and symmetric rectified current flow.
