Infineon FZ400R12KS4HOSA1: High-Performance 1200V IGBT Module for Industrial Drives and Power Conversion
The relentless pursuit of higher efficiency, greater power density, and enhanced reliability in industrial systems has driven the evolution of power semiconductor technology. At the forefront of this innovation is the Infineon FZ400R12KS4HOSA1, a state-of-the-art 1200V IGBT module engineered to meet the rigorous demands of modern industrial drives and advanced power conversion systems.
This module is built upon Infineon's proven Trenchstop™ IGBT7 technology, representing a significant leap forward in performance. The seventh generation IGBTs are renowned for their exceptionally low Vce(sat) saturation voltage, which directly translates to reduced conduction losses. This is complemented by a smooth turn-off characteristic that minimizes switching losses, even at higher switching frequencies. The synergy of these features ensures optimal energy efficiency, a critical factor in high-power applications where energy costs and thermal management are paramount.
Designed for robustness, the FZ400R12KS4HOSA1 offers a high maximum output current of 400A, making it a powerhouse for driving high-power motors in industrial automation, pumps, fans, and compressors. Its 1200V blocking voltage provides a safety margin for operating in 690VAC industrial mains systems, ensuring reliable performance amidst voltage spikes and transients. The module’s low-loss characteristics allow for higher switching frequencies, which enables designers to reduce the size of passive components like filters and inductors, thereby increasing the overall power density of the inverter system.
The package itself is designed for durability and ease of integration. It features a low-inducence design that suppresses overvoltages during switching, enhancing system reliability. The use of AL2O3 (Alumina Oxide) ceramic substrates with sintered technology provides superior thermal cycling capability and mechanical stability, leading to a longer operational lifetime even under stressful thermal conditions. Pre-applied thermal interface material (TIM) on the baseplate further simplifies the assembly process and ensures efficient heat transfer to the cooling system.

Key application areas include:
Industrial Drives: As the core of variable frequency drives (VFDs) for controlling AC motors with precision and high efficiency.
