483-01 - 483-04 Available Qualified Level: JANTX 3 Phase 25 Amp Rectifier Bridge Qualified per MIL-PRF-19500/483 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. ME Package Important: For the latest information, visit our website http://www.microsemi.com.

PART NOMENCLATURE JANTX M19500/ 483 -01 (e3) Reliability Level JANTX = JANTX level Blank = Commercial RoHS Compliance e3 = RoHS compliant (commercial grade only) Blank = non-RoHS compliant MIL-PRF-19500 (Only included in JANTX part number) Power Level (See Electrical Characteristics table) MIL-PRF slash number SYMBOLS & DEFINITIONS Definition Symbol V (BR) V RWM IO VF IR t rr 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). Also sometimes known as PIV. 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.
