VOIDLESS-HERMETICALLY-SEALED
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.
