1N6661 thru 1N6663 VOIDLESS-HERMETICALLY-SEALED STANDARD RECOVERY GLASS RECTIFIERS SCOTTSDALE DIVISION APPEARANCE This “standard recovery” rectifier diode is military qualified to MIL-PRF-19500/587 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 500 mA rated rectifiers for working peak reverse voltages from 225 to 600 volts are hermetically sealed with void-less-glass construction using an internal “Category I” metallurgical bond. The surface mount MELF package configurations are also available by adding a “US” suffix (see separate data sheet for 1N6661US thru 1N6663US). Microsemi 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.
