Subject: Powerex Introduces 2 new High Voltage/Current Diode Modules with 11KV and 6.5KV Blocking Capability
FOR IMMEDIATE RELEASE
Description: Developed to meet the high voltage blocking and high current requirements, Powerex is now offering two new high voltage silicon diode modules (QRSB165001 and QRD6565001) which complement our standard 6500V HVIGBT product offering. Each configuration features ribbon-bonded, 67mm diode elements (two per module) which provide 650A of steady-state current.
Offering an innovative corona resistant package design, these modules are constructed to provide 11KV/650A single and 6.5KV/650A half-bridge configuration while providing 12KV isolation to the baseplate.
11KV is achieved by connecting matched diodes in series. All components and interconnects are isolated from the heat sinking baseplate, offering simplified system assembly and thermal management.
Product Ratings and Characteristics
Both the single QRSB165001, rated at 11,000V/650A, and the dual QRD6565001, rated at 6500V/650A, feature:
• High blocking voltage
• Isolated baseplate
• Elements matched for series operation
• High surge current rating
• Same mounting height to our 6500V HVIGBT modules
• Spherical convex baseplate for lowest thermal resistance
Applications
These devices are designed for high voltage blocking applications, such as DC power supplies, pulse power, front-end converters, clamp diode for multi-level inverters, chopper diodes and laser power supplies.
