MV7654
Bare copper lead version of 1N5811
DESCRIPTION
This “Ultrafast Recovery” rectifier diode series is military qualified to MIL-PRF-19500/477 and
is ideal for high-reliability applications where a failure cannot be tolerated. These industry-
recognized 6.0 Amp rated rectifiers for working peak reverse voltages from 50 to 150 volts are
hermetically sealed with voidless-glass construction using an internal “Category I” metallurgical
bond. These devices are available in both leaded and 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 standard, fast and
ultrafast device types in both through-hole and surface mount packages.

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 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 is reached.

1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Dimension BL shall include the entire body including slugs and sections of the lead over which the diameter is
uncontrolled. This uncontrolled area is defined as the zone between the edge of the diode body and extending
.050 inch (1.27 mm) onto the leads.
4. Dimension BD shall be measured at the largest diameter.
5. In accordance with ASME Y14.5M, diameters are equivalent to
φx
symbology.
Lead Tolerance = + .002 -.003 in
*Includes sections of the lead or fillet over which the lead diameter is uncontrolled.
