VOIDLESS HERMETICALLY SEALED ULTRAFAST
RECOVERY GLASS RECTIFIERS
Qualified per MIL-PRF-19500/477
DESCRIPTION
This “Ultrafast Recovery” rectifier diode series is military qualified and is ideal for high-reliability
applications where a failure cannot be tolerated. The industry-recognized 2.5 amp rated rectifiers
with working peak reverse voltages from 50 to 150 volts are hermetically sealed with voidless glass
construction using an internal
“Category 1”
metallurgical bond. These devices are available in both
surface mount MELF and leaded package configurations. Microsemi also offers numerous other
rectifier products to meet higher and lower current ratings with various recovery time 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.
Average Rectified Output Current: 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 Leakage Current: The maximum 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 occurs.
