483-01 – 483-04
Available 3 Phase 25 Amp Rectifier Bridge
Qualified per MIL-PRF-19500/483
Qualified Level:
JANTX
DESCRIPTION
This series of high-current three-phase bridge rectifiers are constructed with hermetically
sealed rectifiers built with the same design and construction techniques used in military
applications for the upmost in reliability. These include voidless glass encapsulation and
internal "Category 1" metallurgical bonds. They can optionally be purchased built with diodes
that have been screened and mil-qualified to MIL-PRF-19500/483, making them ideal for
applications where failure cannot be tolerated. These 25A rectifier bridges are available with
working peak reverse voltage ratings of 200, 400, 600, or 800 V per leg.

Definition
V(BR)
Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.
VRWM
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.
IO
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 .
VF
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
IR
Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
trr
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.
