VOIDLESS-HERMETICALLY SEALED  
FAST RECOVERY GLASS RECTIFIERS  
S C O T T S D A L E D I V I S I O N  
DESCRIPTION  
APPEARANCE  
This “fast recovery” rectifier diode series is military qualified to MIL-PRF-19500/359  
and is ideal for high-reliability applications where a failure cannot be tolerated.  
These industry-recognized 1.0 Amp rated rectifiers for working peak reverse  
voltages from 200 to 1000 volts are hermetically sealed with voidless-glass  
construction using an internal “Category I” metallurgical bond. These devices are  
similar in ratings to the 1N5615 thru 1N5623 series where surface mount MELF  
package configurations are also available by adding a “US” suffix (see separate  
data sheet for 1N5615US thru 1N5623US). 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.
