KBJ2508 – 800V 25A Bridge Rectifier in KBJ Package | 800V 25A High-Voltage DC Rail Rectifier

The KBJ2508 is an 800V 25A single-phase bridge rectifier delivering high-voltage AC-DC conversion with 350A surge endurance and extremely low 12.5µA reverse leakage. Its 1.0V low VF conduction reduces body heating under heavy inrush, improving overall power efficiency. Packed in a rugged, thermal-efficient KBJ casing, KBJ2508 guarantees long-term reliability for industrial PSU, charger bridges, UPS input rails, and 800V high-current DC bus modules.
