This "Ultrafast Recovery" rectifier diode series is military qualified and is ideal for high-reliability applications where a failure cannot be tolerated. The industry-recognized 20 amp rated rectifiers with working peak reverse voltages from 50 to 150 volts are hermetically sealed with void-less glass construction using an internal "Category 1" metallurgical bond. Microchip also offers numerous other rectifier products to meet higher and lower current ratings with various recovery time requirements including standard, fast and ultrafast device types in both through-hole and surface mount packages.
