1N5550 thru 1N5554
VOIDLESS HERMETICALLY SEALED STANDARD
RECOVERY GLASS RECTIFIERS
Qualified to MIL-PRF-19500/420
DESCRIPTION
This “standard recovery” rectifier diode series is military qualified and is ideal for high-reliability
applications where a failure cannot be tolerated. These industry-recognized 5.0 amp rated
rectifiers for working peak reverse voltages from 200 to 1000 volts are hermetically sealed
with voidless-glass construction using an internal “Category
1”
metallurgical bond. These
devices are also available in surface mount MELF package configurations. 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.

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
excluding all transient voltages (ref JESD282-B).
Average Rectified Output Current: The Output Current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave
input and a 180 degree conduction angle.
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.
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 decay point after a peak reverse current occurs.
