Even better than before: New additions to SCA/SCE- and DCA-series
Autumn 2021 Edition
We have elevated our Diode Module DCA-series and Thyristor-Thyristor/Thyristor-Diode Module SCA/SCE-series to a new level with even better high heat dissipation features as well as an overall lighter structure.
Both of the series have a long, reliable history as one of SanRex’s stable products: DCA-series started its production over 20 years ago while SCA/SCE-series was added to our product catalogue in 2008. Throughout the years we have continued to improve the overall technology to meet the requirements set by customers in order to reach the best possible longevity and quality.​
Internal structure
1. High heat dissipation: The high heat dissipation is made possible with an internal structure that has fewer layers than the previous versions of the same series. This also allows a smaller thermal stress on the thyristor and diode chips that also improves the power cycle capability.
2. Improved longterm reliability: With the decrease of two layers in the internal structure, as well as soldering the chips on both sides, the products’ reliability can be even twice as long as the existing versions of the modules.
Production process
3. Overall lightweight design: By optimising the internal design and materials, we have been able to decrease the weight 10% for SCA/SCE -series and even 20% for DCA -series modules, compared to the existing models.
4. A Green choice: We have decided to use 100% lead-free solder that gives less strain to the environment.
5. Easy availability: The series are completely produced in an automised process - this ensures significantly more efficient production as well as lower cost.
