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.

Reduced system cost thanks to 3-level-topology

Product Portfolio IGBT Driver

Above the Standard

SEMIKRON’s unique product portfolio enables access to all established industries with a one-stop solution that combines state-of-the-art power modules and driver electronics.

SEMIKRON’s IGBT drivers are available as one- or two channel driver boards, two-channel driver cores for PCB-Integration, suitable for any standard semiconductor power module or as Plug-and-Play solutions, which perfectly fit the SEMiX 3 Press-Fit, SEMITRANS 10 and compatible modules.

Cost Efficient

Achieve outstanding system compactness and create space-and cost-effective inverter designs with SEMIKRON’s drivers, utilizing highly integrated ASIC technology. Isolated DC-link voltage and temperature sensor signals at the driver’s interface along with over-voltage and over-temperature lockout also help to reduce system costs significantly.

Time Efficient

More than 25 years of experience in developing innovative IGBT driver electronics enables SEMIKRON to have a short-term solution for almost every challenge related to driver electronics. SEMIKRON’s Plug-and-Play drivers connect directly to most common standard IGBT modules. The IGBT driver cores fit with SEMIKRON’s adapter boards or application sample PCBs. For the latter, SEMIKRON shares the entire manufacturing data to decrease development time, speeding up the time-to-market.


SEMIKRON’s SKYPER and SKHI drivers are well-known, highly robust and reliable IGBT driver solutions, even under demanding environmental conditions.

Over many years of field operation experience the proprietary IGBT driver technology has been relentlessly developed further. This technology sets new standards for the essential features of safe gate control, reliable protection and reinforced insulation.

Key Factors

  • Reinforced insulation for signal and power transmission
  • One- and two-channel driver
  • Up to 1700V transient collector-emmitter voltage
  • Up to 1500V continuous DC link voltage
  • 8Apk to 35Apk output current per channel
  • 1W to 4.2W peak output power per channel
  • Suitable for multi-level topologies and Generation 7 IGBT

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
