KBU10005 – 50V 10.0A Single-Phase Bridge Rectifier in KBU Package | 50V 10A Rectifier Bridge

The KBU10005 is a 50V, 10.0A single-phase bridge rectifier designed for efficient and reliable AC-to-DC power conversion in low-voltage, high-current applications. Featuring an optimized forward voltage drop of 1.05V, the device ensures minimal conduction loss and improved thermal performance during continuous high-load rectification. Capable of handling 300A peak surge current, it protects transformer secondaries and bulk capacitors from repetitive AC cycle peaks and inrush stress. Its ultra-low reverse leakage rating of 10µA reduces off-state power dissipation, providing superior efficiency for 50V rectifier rails in consumer, industrial, and auxiliary power modules. The rugged, compact KBU epoxy-molded package offers excellent electrical isolation, stable pin alignment, mechanical durability, and efficient heat dissipation, making it ideal for PCB-mounted rectifier bridges and compact AC-DC input stages.
