KBJ1510 – 1000V 15.0A Bridge Rectifier in KBJ Package | 1000V 15A Bridge

The KBJ1510 is a 1000V, 15A ultra-high-voltage single-phase full-wave diode bridge rectifier module, optimized for high-voltage AC-to-DC conversion, transformer-based DC bus charging, industrial offline power stages, solar inverter input rails, and infrastructure-grade supply front ends. The internal 4-junction layout ensures symmetrical current sharing, delivering 1.0V low-loss conduction at 100 °C rated load temperature, preserving both power efficiency and thermal reliability. Designed for rugged overload integrity, the bridge tolerates 240A non-repetitive surge transients, while reverse leakage remains tightly regulated at 7.5µA max, guaranteeing stable high-voltage blocking even under long-duration rectifier operation. Packaged in the standard 4-lead KBJ epoxy block package, the KBJ1510 ensures robust PCB lead support, clean pin termination, dependable thermal spreading, and high-voltage creepage confidence in 15A rectification front ends.
