This series of high-current three-phase bridge rectifiers are constructed with hermetically sealed rectifiers built with the same design and construction techniques used in military applications for the upmost in reliability. These include voidless glass encapsulation and internal "Category 1" metallurgical bonds. They can optionally be purchased built with diodes that have been screened and mil-qualified to MIL-PRF-19500/483, making them ideal for applications where failure cannot be tolerated. These 25A rectifier bridges are available with working peak reverse voltage ratings of 200, 400, 600, or 800 V per leg
