In today’s demanding industrial environments, the choice of the right IGBT module can directly impact system efficiency, reliability, and scalability. Two standout models in the field are the FZ2400R12HE4_B9 from Infineon and the SKIIP83EC125T1 from Semikron. Both offer robust solutions for high-power conversion, motor drives, and energy systems. This article provides an in-depth technical comparison, practical application insights, and highlights key factors for industrial decision-makers considering these modules.
FZ2400R12HE4_B9:
SKIIP83EC125T1:
For applications demanding extremely high current handling, the FZ2400R12HE4_B9 outpaces the SKIIP83EC125T1 with its 2400A continuous and 4800A pulse collector capability. This makes it an exceptional choice for heavy-duty high-power inverters and large AC drive systems. The IHM-B module package also leverages superior insulation (CTI >400) and integrated thermal management, reducing system integration time and ensuring reliable field operation.
In contrast, the SKIIP83EC125T1 is optimized for flexibility and integration. Its compact design, along with low saturation voltage (VCE(sat)), suits precise motor control in AC/DC servo platforms and space-constrained UPS systems. The module supports fast dynamic braking—ideal for high-cycle industrial automation.

*Some sources indicate VCES can reach 2500V in specific variants.
When scaling up to utility-grade converters or industrial drives, the FZ2400R12HE4_B9 shines due to its current-handling capacity and endurance at high temperatures. Applications such as heavy-duty motor drives, renewable energy inverters, and large traction systems benefit from stability and reduced maintenance cycles offered by its integrated thermal pad and robust chassis.
The SKIIP83EC125T1, with its compact and user-friendly design, is best suited for precision control environments—such as CNC machinery, robotics, and high-reliability UPS where fast switching and limited footprint are essential. Its efficient thermal management and easy PCB integration accelerate development cycles and streamline logistics in project deployment.
Today’s market increasingly demands high-efficiency IGBT modules with integrated protection and simplified installation. Fast Trench/Field-stop designs, such as those found in Infineon’s IGBT4 lineup, deliver both performance and reliability. On the other hand, platforms like Semikron’s SKIIP series focus on system modularity and deployment flexibility, aligning with trends towards smart manufacturing and Industry 4.0.
