APPEARANCE
This “standard recovery” rectifier diode series is military qualified to MIL-PRF19500/228 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 1N5614 thru 1N5622 series where surface mount MELF
package configurations are available by adding a “US” suffix (see separate data
sheet for 1N5614US thru 1N5622US). 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.
