Semikron SKiiP39AC126V20 | High-Reliability IPM with Sintering Technology
The Semikron SKiiP39AC126V20 is not just another IGBT module; it's a fully integrated intelligent power system engineered for applications where failure is not an option. This 1200V, 3-phase inverter module combines robust power stages with sophisticated driver and protection circuits, leveraging Semikron's pioneering SKiiP technology. It's the definitive choice for high-power motor drives, renewable energy systems, and critical infrastructure that demand maximum uptime and operational longevity.
Technical Deep Dive: Where Performance Meets Reliability
-
Revolutionary Sintering Technology: Unlike conventional modules that rely on solder joints, the SKiiP39AC126V20 utilizes a pressure-sintered silver layer to bond the power die to the substrate. This solid-state diffusion bond eliminates solder fatigue—the primary failure mechanism in high-power modules.
Application Value: This results in a 5-10x increase in power cycling capability and superior thermal conductivity. For your application, this means a significantly longer operational lifetime, reduced maintenance costs, and the ability to withstand harsh operating conditions, especially in systems with frequent load changes like servo drives or wind turbine pitch controls. -
Integrated Digital Microcontroller Driver: The module features a highly integrated gate driver board with a digital signal processor. This driver is precisely matched to the IGBTs, ensuring optimized switching characteristics (dV/dt and di/dt control).
Application Value: This integration simplifies your design effort, shortens time-to-market, and minimizes electromagnetic interference (EMI). The on-board protection features, including VCEsat monitoring, under-voltage lockout (UVLO), and temperature sensing, provide a comprehensive safety net that enhances overall system robustness, reducing the need for external protection circuitry.
Unlocking Value Across Demanding Applications
- Wind Turbine Converters: In the nacelle of a wind turbine, component replacement is a major logistical and financial challenge. The exceptional reliability and long service life of the SKiiP39AC126V20, thanks to its sintered joints, directly translate to increased energy production and lower operational expenditure.
- Heavy-Duty Industrial Drives: For applications like mining conveyors, industrial presses, or traction drives, the constant start-stop and torque variations subject power modules to intense thermal stress. The SKiiP39AC126V20's superior thermal cycling endurance ensures it performs reliably cycle after cycle, preventing costly downtime.
- Uninterruptible Power Supplies (UPS): In data centers and critical facilities, the efficiency and reliability of a UPS are paramount. The low conduction and switching losses of this module improve overall system efficiency, reducing cooling costs. Its integrated nature ensures a dependable power backbone when it's needed most.
- Servo Drives: The fast and precise control required in industrial automation and robotics demands a power module with rapid response and high durability. The SKiiP39AC126V20's optimized driver and robust construction deliver the performance needed for high-dynamic servo control applications.

Selection Insight: IPM vs. Discrete IGBT Solutions
Engineers often weigh the benefits of an Intelligent Power Module (IPM) like the SKiiP39AC126V20 against a solution built from discrete IGBTs and a separate driver board. While a discrete approach may offer granular design flexibility, it introduces significant complexity in driver design, EMI filtering, and ensuring thermal and electrical compatibility. The SKiiP39AC126V20 provides a pre-validated, highly reliable system-in-a-package. It is the superior choice for projects prioritizing speed to market, system-level reliability, and reduced assembly complexity. If your goal is to build a robust power converter with guaranteed performance, this IPM is your most direct path. To see other available solutions, you can explore more IGBT modules on our site.
