DESCRIPTION
This 1N3889 – 1N3891 and 1N3893 family of rectifier devices are suitable for applications in
DC power supplies, inverters, converters, choppers and ultrasonic systems as well as other
applications. It can also be used as a free-wheeling diode. They are military qualified up to a
JANTXV level on select part numbers and they are available in both standard and reverse
polarities. Microsemi also offers numerous other products to meet higher and lower power
voltage regulation applications.

SYMBOLS & DEFINITIONS
Definition
Junction Capacitance: The junction capacitance in pF at a specified frequency.
Average Forward Current: The average forward current dc value, no alternating component.
Maximum Forward Surge Current: The forward current, surge peak or rated forward surge 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.
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
Repetitive Peak Reverse Voltage: The peak reverse voltage including all repetitive transient voltages but excluding all
non-repetitive transient voltages.
Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range
excluding all transient voltages (ref JESD282-B). Also sometimes known as PIV.
