Infineon Technologies Thyristor prime discs

Infineon offers a complete thyristor module and disc portfolio for UPS bypasses and Static Transfer Switches (STS). It is also available as pre-assembled cooling blocks or fully integrated stack solutions. Using a single 111 mm thyristor disc and forced air cooling, the existing limit is 2.0 MVA at 480 V. New requirements for data centers push the limits further for more power density and compact design.
