Infineon K40T1202: High-Performance 1200V TRENCHSTOP™ IGBT for Industrial Drives and UPS Applications

The demand for robust and efficient power switching solutions in industrial applications continues to grow, driven by the need for higher reliability and energy savings. Addressing this need, the Infineon K40T1202 stands out as a premier 1200V IGBT built on the advanced TRENCHSTOP™ technology. This device is engineered specifically to meet the rigorous performance requirements of industrial drives and Uninterruptible Power Supplies (UPS), offering an optimal blend of low saturation voltage and minimal switching losses.

A key advantage of the K40T1202 is its low VCE(sat) characteristic, which significantly reduces conduction losses. This translates into higher efficiency, especially in applications operating at continuous high currents. Furthermore, the soft switching performance of this IGBT minimizes electromagnetic interference (EMI), a critical factor for compliance with international standards and for improving system reliability. The device is also designed with a positive temperature coefficient, which simplifies the paralleling of multiple IGBTs for higher power applications without the risk of thermal runaway.

The robust 1200V breakdown voltage ensures sufficient margin for handling voltage spikes commonly encountered in industrial environments, particularly in 3-phase systems operating at 480VAC. This makes the K40T1202 exceptionally reliable in demanding settings such as motor drives and industrial inverters. Additionally, its fast switching capability allows for higher frequency operation, which can lead to reductions in the size and cost of passive components like inductors and capacitors.

For UPS systems, where efficiency directly impacts battery life and thermal management, the low loss characteristics of the K40T1202 contribute to higher overall system efficiency. The IGBT’s high short-circuit ruggedness provides an added layer of protection, ensuring system stability under fault conditions. Packaged in the industry-standard TO-247 package, it also offers excellent thermal performance and ease of mounting to heat sinks.

ICGOODFIND: The Infineon K40T1202 is a high-efficiency, robust 1200V IGBT that leverages TRENCHSTOP™ technology to deliver superior performance for industrial drives and UPS systems. Its excellent trade-off between low conduction losses and soft switching characteristics makes it an ideal choice for designers aiming for higher power density and reliability.
