August 2016 – Introduction to Semikron’s SEMIPACK Thyristors

Published on: 26/08/2016

SEMIPACK thyristors were the first insulated module on the market and today it is still a state-of-the-art component 40 years later


Semikron boasts a comprehensive range of packages and configurations to suit applications such as drives, power supplies or power quality.


SEMIPACK Thyristors: Benefits

The SEMIPACK is a well established module which conforms to industrial standard on footprint and module outline guidelines. With a comprehensive product range, the optimal solution can be found for any application. Using SemiSel, a free online calculation and stimulation tool for losses and temperature, the power electronic system developer is able to make the perfect power module.



The target applications for the thyristor, thyristor/diode or diode modules include rectifiers (single-phase, three-phase, controlled, half-controlled or controlled) for inverters or UPS systems, soft start applications and control systems.  


Product Range

The SEMIPACK range offers seven comprehensive module lines: with voltages from 800V to 2200V, insulation voltages of 3.6Kv, 4.8Kv@1s and a current range from 15A to 1200A. Uncontrolled, half-controlled and controlled rectifier modules are available as well as single thyristor or diode modules. Also, fast diodes come in SEMIPACK modules. Further more, different contact technologies – soldered contact, bonded contact or pressure contact modules are available.
