Product Highlights
The Latest Generation 7 IGBT for Highest Supply Chain Safety
Whenever power quality and efficiency are driving factors in power electronics applications, 3-level topologies are the key. This is especially true for renewable energy applications where the combination with the latest Generation 7 IGBTs sets new benchmarks.
The SEMITRANS 10 MLI enables energy storage converters to reach voltage ranges up to 1000VAC (1500VDC) in 3-level NPC topology and increases converter efficiency.
Reduced system cost thanks to 3-level-topology
- Up to 1.5 MW without paralleling
- Lower switching losses thanks to 1200V IGBT
- Generation 7 IGBT
- Reduced diameters or cable losses
- Reduced cooling requirements
Comprehensive Sixpack and 3-Level Module Family
With its comprehensive portfolio and its optimised design, the SEMiX 5 is ideal for high-performance inverter architectures. The press-fit contacts ensure fast and solder-free driver board assembly, increased reliability and reduced assembly cost. An adapter board for easy gate drive integration is also available.
The internal chip layout is optimised for enhanced thermal performance, reducing operating temperatures and thus boosting reliability. The housing features rugged moulded power terminals for superior mechanical stability.
Key Features

Thermal Interface Materials
Stay Cool – Heat Dissipation is Our Job
SEMIKRON was the first power module manufacturer on the market to offer power modules with pre-applied thermal interface material. With more than two decades of field experience and more than 15 million pre-printed modules in the field, benchmarks are being set. The modules with pre-applied TIM are printed in a clean environment on an automated and SPC controlled silk screen and stencil printing line.
For each requirement SEMIKRON offers the right choice of material. In addition to the standard silicone thermal grease, phase change materials and high performance thermal paste with improved thermal performance are also available.
SEMIKRON offers either thermal grease or phase change mate- rials depending on customer requirements (e.g. performance increase, reduced handling effort) and module type (with or without baseplate). Phase change materials have a solid consistency at room temperature, fully exploiting the advantages a non-smearing TIM layer offers, with no drawbacks. Baseplate- less modules, on the other hand, usually require a lower-viscosity material to help improve robustness during assembly. Here, thermal grease is the preferred solution.
Key Features
- Increased productivity thanks to reduced handling costs and improved logistics
- Low thermal resistance with optimised TIM layer thickness
- Improved lifetime and reliability
- Improved assembly robustness
- Modules can be shipped directly to the assembly line without any additional treatment processes
- Lower overall costs
