Infineon FS100R12KT4: High-Performance 1200V PrimePACK™ 3 IGBT Module for Industrial Drives and UPS

The relentless pursuit of higher efficiency, power density, and reliability in industrial automation and energy infrastructure has driven power semiconductor technology to new heights. At the forefront of this evolution is the Infineon FS100R12KT4, a 1200V IGBT module that sets a formidable benchmark for performance in demanding applications such as industrial motor drives and uninterruptible power supplies (UPS). Encased within the robust and industry-standard PrimePACK™ 3 package, this module is engineered to meet the rigorous demands of modern high-power systems.

Engineered for Superior Performance and Efficiency

The core of the FS100R12KT4's prowess lies in Infineon's advanced IGBT4 trench-stop technology. This technology is pivotal in achieving an optimal balance between low saturation voltage (Vce(sat)) and minimal switching losses. The result is significantly reduced conduction and switching losses, which directly translates into higher overall system efficiency and lower operating temperatures. For end-users, this means reduced energy consumption and lower cooling requirements, leading to a smaller system footprint and lower total cost of ownership.

The module's high current rating of 100A (at Tc=80°C) and 1200V voltage class make it an ideal choice for three-phase inverters operating from standard industrial bus voltages. Its design is optimized for switching frequencies commonly used in motor control and UPS applications, ensuring smooth operation and precise control.

Robustness and Reliability in Demanding Environments

Industrial and UPS environments are characterized by electrical stress, thermal cycling, and the need for continuous operation. The FS100R12KT4 is built to thrive in these conditions. The PrimePACK™ 3 platform itself offers superior thermal performance and high power cycling capability, thanks to its large baseplate and optimized internal layout. This robust mechanical construction ensures long-term reliability even under intense thermal stress.

Furthermore, the module offers a very high short-circuit withstand time (tSC), a critical safety feature that provides the control system with sufficient time to react to fault conditions and shut down safely, thereby protecting the drive and the motor.

Optimized for System Integration

Designing a high-power inverter requires careful consideration of parasitics and thermal management. The FS100R12KT4 simplifies this process. The low-indunce design of the PrimePACK™ 3 package minimizes overvoltages during switching, which enhances system safety and allows for more predictable performance. The module also features a PressFIT contact option for the auxiliary emitter and temperature sensor (NTC) pins. This solderless press-fit technology enables faster, more automated assembly, reduces manufacturing costs, and improves connection reliability by eliminating solder joint fatigue.

ICGOODFIND Summary:

The Infineon FS100R12KT4 is a high-performance power module that stands out for its exceptional efficiency, ruggedness, and system integration benefits. Leveraging mature and proven IGBT4 technology within the reliable PrimePACK™ 3 package, it provides a robust and future-proof solution for engineers designing next-generation industrial drives and UPS systems where reliability and energy savings are paramount.
