Overview of Powerex IN3288A, AR to IN3297A, AR General Purpose Rectifiers
The datasheet provides detailed information about the Powerex IN3288A, AR to IN3297A, AR series of general purpose rectifiers. These components are designed to handle an average forward current of 100 amperes and have a voltage rating up to 1400 volts. The rectifiers are suitable for a wide range of applications, including welders, battery chargers, electrochemical refining, metal reduction, and other general industrial high current rectification tasks.
Features
These rectifiers come with standard and reverse polarities and are equipped with color-coded seals for easy identification. They boast high surge current ratings and are specified for both parallel and series operation, ensuring flexibility in various circuit configurations. The encapsulation of the rectifiers is compression-bonded, which enhances their reliability and performance in challenging conditions.
Ordering Information
To facilitate ease of ordering, the datasheet includes a table where complete part numbers can be chosen based on the desired voltage and current requirements. The part numbers range from IN3288A to IN3297A, corresponding to incremental voltage ratings from 100 to 1400 volts, all supporting 100 amperes of average forward current.
Absolute Maximum Ratings
The provided absolute maximum ratings highlight critical parameters such as RMS forward current (160A), average forward current (100A), and one-half cycle surge current (2300A at 60 Hz under load). It also details the fusing time (22000 A^2sec at 60 Hz), storage temperature range (-40 to +200°C), operating temperature range (-40 to +200°C), and mounting torque (120 in-lb when lubricated).
Electrical and Thermal Characteristics
Electrical specifications include a maximum forward voltage drop of 1.5 volts at 100A, while thermal characteristics detail a maximum junction-to-case thermal resistance of 0.40°C/W for all types and a case-to-sink thermal resistance of 0.15°C/W when lubricated. The datasheet clarifies the capabilities of the rectifiers concerning repetitive peak reverse voltage (ranging from 100V to 1400V), and non-repetitive peak reverse voltage (from 200V to 1800V), along with maximum DC blocking voltage and reverse leakage current parameters.
