KBU1010 – 10A 1000V Single-Phase Silicon Bridge Rectifier | 4-Pin KBU Package, PCB Mount

If you need a dependable AC-to-DC conversion solution for high-current applications, the KBU1010 silicon bridge rectifier delivers strong forward conduction and high surge tolerance. Rated for 10A continuous output current, this rectifier easily handles demanding loads such as SMPS modules, DC motors, LED drivers, and battery chargers.

With a peak reverse voltage of 1000V, it protects sensitive electronics from reverse-polarity damage, making it suitable for industrial and commercial power stages. The compact 23.7mm KBU housing provides efficient heat dissipation, and the silicon-junction design maintains stability in extreme temperature ranges from –55°C to +150°C.

Whether you are repairing a UPS, upgrading a rectifier stage, building a transformer-based power supply, or designing a new control board—KBU1010 offers consistent rectification, minimal loss, and long-term reliability.
