Infineon 98-1073PBF High-Performance IGBT Module for Industrial Motor Drives and Power Conversion

The Infineon 98-1073PBF stands as a premier power semiconductor module engineered to meet the rigorous demands of modern industrial automation and energy conversion systems. As a member of Infineon’s established IGBT3 (Trench Stop) technology family, this module is optimized for high-power switching applications, delivering a robust combination of efficiency, power density, and reliability that is critical for performance-driven sectors.

Designed primarily for industrial motor drives, this IGBT module facilitates precise control over AC motors in applications ranging from pumps and compressors to conveyor systems and industrial fans. Its ability to handle high currents and voltages allows for the construction of compact and efficient inverters that convert DC power to variable-frequency AC, enabling sophisticated speed and torque control of electric motors. This results in significant energy savings and improved process control in manufacturing environments.

Beyond motor control, the 98-1073PBF is equally adept at serving as the core switching element in various power conversion systems. This includes uninterruptible power supplies (UPS), solar inverters, and industrial welders, where efficient and reliable energy processing is non-negotiable. The module’s low VCE(sat) saturation voltage and minimal switching losses are key to achieving high system-level efficiency, reducing heat generation, and simplifying thermal management design.

A critical factor in its high performance is the advanced packaging and internal design. The module incorporates a low-inductance design that minimizes overvoltage spikes during fast switching transitions, enhancing system safety and allowing for higher switching frequencies. The use of AL2O3 (Alumina) ceramic substrates with direct copper bonding ensures excellent electrical isolation and superior thermal cycling capability, which directly translates to a longer operational lifetime even under stressful conditions. The press-fit pins, instead of traditional solder pins, offer a more reliable mechanical connection and simplify the assembly process for high-volume manufacturing.

Reliability is further reinforced by its wide operating junction temperature range (Tvj op), making it suitable for harsh industrial environments where ambient temperatures can fluctuate. This ruggedness ensures stable operation and reduces the risk of failure, a paramount concern for critical infrastructure.

ICGOOODFIND: The Infineon 98-1073PBF is a high-performance IGBT module that exemplifies engineering excellence for industrial power electronics. It successfully balances high efficiency, robust power handling, and exceptional reliability, making it an ideal solution for demanding applications in industrial motor drives and advanced power conversion systems.
