Stable and Efficient, Hassle-Free Compatibility — Zenli SKKD Series Rectifier Diode Modules

As a leading supplier in the industrial power semiconductor sector, Zenli's SKKD162 and SKKD212 M3 series rectifier diode modules have consistently provided high-quality rectifier products to customers worldwide. Thanks to their perfect compatibility with Semikron's standard dimensions and their stable, reliable performance, these modules have become the trusted long-term choice for numerous industrial equipment manufacturers.

This series features the standard SEMIPACK 2 package in an M3form factor. With pin definitions and mounting dimensions identical to those of corresponding Semikron models, these modules enable seamless replacement without requiring modifications to existing PCB designs, significantly reducing replacement costs and system upgrade cycles for customers. The SKKD162 series has a rated forward current of up to 162A, while the SKKD212 series is rated up to 212A. Reverse peak voltage ratings range from 1200V to 1800V, covering multiple levels to meet rectification needs across different power ratings.

In terms of performance, both modules utilize advanced DBC (Direct Bonded Copper) technology and an optimized chip layout, offering excellent thermal conductivity and electrical insulation properties. With a junction temperature operating range of -40°C to +135°C, they can operate stably over the long term in harsh industrial environments. Their low forward voltage drop design effectively reduces conduction losses and improves overall system efficiency; simultaneously, the modules possess robust surge current withstand capability, enabling them to effectively handle transient overloads commonly encountered in industrial settings.

Currently, Zenli's SKKD162 and SKKD212 M3 series rectifier diode modules are widely used in industrial inverters, DC motor drives, UPS systems, welding machines, electroplating power supplies, and renewable energy generation equipment. With stable product quality, ample stock availability, and comprehensive technical support services, the Zenli brand continues to create value for customers and supports the high-quality development of industries such as industrial automation and electrical engineering.
