HIGH VOLTAGE RECTIFIERS  
DESCRIPTION  
APPEARANCE  
These “standard recovery” high voltage rectifier diode series are military qualified to  
MIL-PRF-19500/279 for the 1N3644 thru 1N3647. Others such as the 1N5181 thru  
1N5184 meet or exceed requirements of MIL-PRF-19500/389. They are ideal for  
high-reliability where a failure cannot be tolerated for high voltage applications.  
These 0.10 and 0.25 Amp rated rectifiers at 55ºC for working peak reverse voltages  
from 1000 to 10,000 volts are hermetically sealed with voidless-glass construction  
using an internal “Category I” metallurgical bond. Surface mount MELF package  
configurations are also available by adding “SM” suffix. 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.
