Learn more about Semikron’s Generation 7 IGBTs and listen to the interview about the new benchmark for motor drives

Semikron's Generation 7 IGBTs

SEMIKRON is a leading manufacturer of semiconductor components, including power modules and systems. Based in Germany, SEMIKRON specialises in Discrete Semiconductors, Transistors, Diodes, Thyristors, IGBTs, MOSFETs, Thyristor Diode Modules, Pulse Transformers and Power Assemblies.


Semikron’s Generation 7 IGBTs

SEMIKRON’s Generation 7 IGBTs feature the latest in IGBT chip technology and delivers enormous benefits to engineers. Benefits of using SEMIKRON’s Generation 7 IGBTs are lower forward voltage drop and optimised switching performance, approximately 25% smaller chips which offer higher nominal currents in existing power module packages.

Join James Willford and Werner Obermaier as they look at the reasons why generation 7 IGBTs are the new benchmark for motor drives. Watch the interview here.

Semikron’s Generation 7 IGBTs feature four main advantages compared to previous generations:

  • Higher reliability thanks to increased humidity robustness
  • Lower conduction losses (Vce, sat)
  • An increased overload capability
  • A smaller physical chip size


The generation 7 IGBTs represent the latest IGBT chip technology. This new generation is specifically designed to match the requirements of motor drive applications. The IGBTs come with a significant lower forward voltage drop and deliver optimised switching performance. Thanks to roughly 25% smaller chips, higher nominal currents can fit into existing power module packages.

In application, the IGBT 7 provides reduced power losses or increased maximum output power and power density. Thanks to the smaller size of Generation 7 IGBT chips with the same nominal chip current, it is now possible to accommodate a larger nominal chip current in the same module package. This results in two possible options to use Generation 7 IGBTs: Either in the same current rating but smaller chip area or with the same chip area and increased nominal current rating.

This translates into lower system costs. As to motor drives, the generation 7 IGBT will initially be introduced into conventional drive topologies: CIB (Converter-Inverter-Brake), sixpack and half-bridge configurations. For low and medium power drives, MiniSKiiP and SEMITOP E1/E2 are the first available choice. For higher power classes IGBT 7 is available in SEMiX 3 press-fit and SEMiX 6 press-fit. More power modules are to follow.
