June 2020 – Semikron’s Bipolar Modules

Published on: 19/06/2020

Semikron’s SEMIPACK was the first insulated power module on the market, and 40 years later Semikron’s Bipolar Modules are still a pioneering range in power electronics

Semikron’s Bipolar module product family boasts a comprehensive range of packages and configurations from the market leader to suit applications like drives, power supplies or power quality.

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


Semikron’s Bipolar Modules: Benefits

SEMIPACK delivers a well-established industrial standard with regard to footprint and module outline. Semikron’s SemiSel provides a free online calculation and simulation tool for losses and temperature, so that the power electronic system developer is able to make the perfect power module choice.


Product Range

Semikron’s SEMIPACK product line consists of seven modules covering voltage classes from 800V to 2200V, insulation voltages of 3.6kv, 4.8kv@1s and a current range from 15A to 1360A. the range includes uncontrolled, half-controlled and controlled rectifier modules. Semikron also offer custom topologies, single thyristor or diode modules and SEMIPACK modules featuring fast switching diodes for dedicated applications. The SEMIPACK FAST product line covers a current range form 40A to 600A with voltage classes from 600V to 1700V. The portfolio of the SEMIPACK product line is extended continuously to meet market requirements.
