1N6661US [Microchip]

These “standard recovery” rectifier diodes are military qualified to MIL-PRF-19500/587 and is ideal for high-reliability applications where a failure cannot be tolerated. They have a 500 mA rating with working peak reverse voltages from 225 to 600 volts and are hermetically sealed with void-less-glass construction using an internal “Category I” metallurgical bond. The axial-leaded package configurations are also available by deleting the “US” suffix (see separate data sheet for 1N6661 to 1N6663). Microchip also offers numerous other rectifier products to meet higher and lower current ratings with various recovery time speed requirements including Fast and Ultrafast device types in both through-hole and surface mount packages.
