Infineon FS35R12KT3: High-Performance 1200V IGBT Module for Industrial Drives and Power Conversion

The demand for robust, efficient, and reliable power conversion is paramount in modern industrial systems. Addressing this need, the Infineon FS35R12KT3 stands out as a premier 1200V IGBT module engineered specifically for high-performance industrial drives and advanced power conversion applications. This module exemplifies the cutting-edge in power semiconductor technology, delivering superior efficiency, power density, and durability.

At the core of the FS35R12KT3 is Infineon's advanced TrenchStop™ IGBT7 technology. This latest generation chip technology sets a new benchmark for performance by significantly reducing both static and dynamic losses. The result is a remarkably low V_CE(sat) (saturation voltage) coupled with soft switching characteristics, which are crucial for minimizing switching losses and electromagnetic interference (EMI). This makes the module exceptionally efficient, even at high switching frequencies, enabling system designers to achieve higher power density and reduce the size of heatsinks and overall system footprint.

The module is rated for a nominal current of 35A, making it an ideal solution for mid-power applications such as:

Industrial Motor Drives: Providing precise and efficient control for AC motors in automation, pumps, fans, and conveyor systems.

Uninterruptible Power Supplies (UPS): Ensuring high efficiency and reliability in critical power backup systems.

Solar Inverters and Renewable Energy Systems: Enabling efficient power conversion in solar and other renewable energy installations.

Industrial Welding Equipment: Delivering the robust and controlled power required for welding applications.

A key feature of the FS35R12KT3 is its high operational reliability and robustness. It offers an extended short-circuit withstand time (t_sc) of 3µs, providing a critical safety margin in fault conditions. The module also features a low thermal resistance and a maximum operating junction temperature (T_vjop) of 175°C, which enhances its ability to handle overloads and operate in demanding environmental conditions. The integrated NTC thermistor facilitates accurate temperature monitoring, allowing for proactive thermal management and system protection.

The package itself is designed for durability and ease of use. The industry-standard EconoDUAL™ 3 package ensures mechanical robustness and excellent thermal cycling capability. The press-fit pin technology allows for solder-free assembly, streamlining the manufacturing process and improving long-term reliability by eliminating solder fatigue.

ICGOO FIND: The Infineon FS35R12KT3 is a top-tier power module that encapsulates the best of modern semiconductor innovation. Its use of IGBT7 technology delivers a compelling combination of ultra-low losses, high power density, and exceptional reliability, making it a future-proof choice for designers aiming to optimize the performance and efficiency of their industrial power electronic systems.
