1N6626US thru 1N6631US
VOIDLESS-HERMETICALLY-SEALED
SURFACE MOUNT ULTRA FAST
RECOVERY GLASS RECTIFIERS
SCOTTSDALE DIVISION
DESCRIPTION
This “Ultrafast Recovery” rectifier diode series is military qualified to MIL-PRF-
19500/590 and is ideal for high-reliability applications where a failure cannot be
tolerated. These industry-recognized 2.0 to 4.0 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 also available in axial-leaded packages for thru-hole mounting (see separate
data sheet for 1N6626 thru 1N6631). 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.

SYMBOLS & DEFINITIONS
Definition
Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.
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 Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
Capacitance: The capacitance in pF at a frequency of 1 MHz and specified voltage.
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.
