RS2504 – 400V 25A Bridge Rectifier in KBU Package | 400V 25A Heavy-Load AC-DC Rectifier Bridge

Designed for 400V AC-to-DC power conversion, the RS2504 delivers 25A continuous rectified DC output with 350A surge tolerance for reliable operation in high-inrush and mains-transient environments. Its ultra-low 12.5µA reverse leakage and low 1.1V forward drop ensure efficient, low-heat rectification. Housed in a rugged KBU thermal package, RS2504 guarantees long-term reliability for industrial PSUs, charger input bridges, DC rail modules, and high-voltage 25A rectification units.
