The SEMIKRON SKD31/06 is a three-phase diode bridge rectifier module providing 35A continuous output current at a 600V blocking voltage. Built on SEMIKRON's well-established SKD package platform, this module integrates six rectifier diodes into a single isolated baseplate assembly, simplifying board layout and thermal management. Designed for direct mounting to a heatsink, the SKD31/06 delivers low forward voltage drop and excellent thermal cycling performance, making it a dependable front-end rectifier solution in demanding industrial environments where reliability and compactness are both critical requirements.

The SKD31/06 sees widespread deployment as an uncontrolled AC-to-DC front-end in variable frequency drives, servo amplifiers, and DC bus power supplies operating from three-phase 400V mains. It is also used in welding equipment, elevator drives, crane and hoist controls, and industrial UPS systems where a robust, self-contained bridge rectifier is preferred over discrete component assemblies. The module's isolated copper baseplate enables straightforward heatsink integration in both chassis-mount and DIN-rail enclosure designs, and its standardized SKD footprint allows drop-in replacement across a wide range of legacy and current-generation drive platforms.

Quick Reference: SKD31/06

Key Features of the SKD31/06:

• Three-phase full-wave bridge rectifier topology with six integrated diodes in a single module
• 35A average output current rating with 600V repetitive peak reverse voltage (V_RRM)
• Isolated copper baseplate for direct heatsink mounting, minimizing thermal resistance and simplifying system integration
• Low forward voltage drop across the diode array, reducing conduction losses and improving overall system efficiency
