KBU1010 – 1000V 10.0A Single-Phase Bridge Rectifier in KBU Package | 1000V 10A Input Power Bridge

The KBU1010 is a 1000V 10.0A single-phase bridge rectifier diode module designed for ultra-high-line AC to DC conversion in industrial offline power rails, infrastructure rectifier stages, large capacitor charging systems, transformer fed front-end bridges, SMPS input modules, and medium-to-heavy 10A single-phase AC-DC converter boards demanding exceptional surge immunity and excellent thermal reliability. Featuring ultra-low reverse leakage of 10µA, it improves standby efficiency and prevents thermal overstress during AC cyclic reverse-bias operation. With 300A surge withstand capability, the device protects AC input rails from transformer inrush peaks, high-energy transient faults, and capacitive load charging stress. The insulated KBU package offers strong mechanical endurance, stable lead pin alignment, high electrical isolation safety, and dependable thermal conduction suitable for continuous high-duty rectifier environments in industrial and consumer energy conversion systems.
