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.
For ANPC topologies, SEMIKRON’s new SEMITRANS 20 power module combines low stray inductance, high power density and Generation 7 IGBTs to set a new benchmark. This package design, based on standard half-bridge topology, allows a simple ANPC layout with low inductance DC-link connections.

Thermal Interface Materials (TIM)
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 in thermal paste form. With more than two decades of field experience and more than 17 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 silkscreen 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 materials 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 optimized 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
