50mm Thyristor/Diode Modules Reduce Costs

Infineon Technologies AG extends its product portfolio of thyristor/diode modules in solder bond technology with a 50mm module. These bipolar modules address the growing market for cost-effective solutions even in demanding applications. Depending on the module, market prices are approximately 25 percent lower than comparable pressure contact variants. Solder bond modules are well-suited for applications where the high robustness of pressure contact technology is not necessarily a must. Typical applications for the new 50mm modules are drives, power supplies and welding.

With the release of the new 50mm modules Infineon Technologies Bipolar complements the existing product portfolio of bipolar modules. The 50mm variant covers current ratings from 280A to 330A. The 20mm and 34mm variants have been in production for more than two years and proven their reliability in the field. All modules have been developed as cost and performance optimized alternative to pressure contact technology. They are packaged in industrial standard housings with an electrically-insulated base plate.

The new 50mm modules as well as the 20mm and 34mm modules in solder bond technology are available in high quantities. All modules are offered in the topologies thyristor/thyristor, thyristor/diode and diode/diode with a blocking voltage of 1600V and in current ratings from 55A to 330A. Infineon is planning to release additional module types with blocking voltages of 1800V and 2200V in 2017.
