DESCRIPTION APPEARANCE
This “Ultrafast Recovery” rectifier diode series is military qualified to MIL-PRF-
19500/503 and is ideal for high-reliability applications where a failure cannot be
tolerated. These industry-recognized 3, 6, and 12 Amp rated rectifiers (TL =70ºC) in
different package sizes for working peak reverse voltages from 50 to 150 volts are
hermetically sealed with voidless-glass construction using an internal “Category I”
metallurgical bond. These devices are also available in surface mount MELF
package configurations by adding a “US” suffix (see separate data sheet for
1N6073US thru 1N6081US). Microsemi also offers numerous other rectifier
products to meet higher and lower current ratings with various recovery time speed
requirements including standard, fast and ultrafast device types in both through-hole
and surface mount packages.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
