| 1N4942 thru 1N4948 VOIDLESS-HERMETICALLY SEALED FAST RECOVERY GLASS RECTIFIERS SCOTTSDALE DIVISION DESCRIPTION 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.

Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range. Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. Maximum Leakage Current: The maximum leakage current that will flow at the specified voltage and temperature. Capacitance: The capacitance of the TVS as defined @ 12 volts at a frequency of 1 MHz and stated in picofarads. Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from the forward direction to the reverse direction and a specified recovery decay point after a peak reverse current is reached.
