1N4942 thru 1N4948
VOIDLESS-HERMETICALLY SEALED
FAST RECOVERY GLASS RECTIFIERS
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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
