Infineon IPA90R340C3: A High-Performance 900V CoolMOS™ Power Transistor

In the realm of high-voltage power conversion, efficiency, reliability, and thermal performance are paramount. The Infineon IPA90R340C3 stands out as a premier solution, engineered to meet the rigorous demands of modern switch-mode power supplies (SMPS), industrial drives, and renewable energy systems. As part of Infineon's renowned CoolMOS™ C3 series, this 900V power MOSFET leverages superjunction technology to deliver exceptional performance where it matters most.

The cornerstone of the IPA90R340C3 is its ultra-low on-state resistance (RDS(on)) of just 340mΩ. This remarkably low resistance minimizes conduction losses, allowing for higher efficiency power conversion even under heavy load conditions. By reducing energy wasted as heat, the transistor enables designers to create more compact and energy-efficient systems without compromising on power handling capabilities.

Another critical advantage is its superior switching performance. The CoolMOS™ C3 technology significantly reduces switching losses, which is crucial for high-frequency operations. This enables power supplies to operate at higher frequencies, leading to a reduction in the size of passive components like inductors and transformers. The result is a more compact, lighter, and often lower-cost overall design.

Thermal management is a key challenge in high-power applications. The IPA90R340C3 excels here with its excellent thermal characteristics, facilitated by low losses and a robust package. This ensures reliable operation even in elevated ambient temperatures, enhancing the longevity and durability of the end product. Designers can push their systems harder with confidence, knowing the component is built to handle thermal stress.

Furthermore, the 900V drain-source voltage rating provides a formidable safety margin for applications operating from universal input voltages (85V AC to 305V AC) or in environments prone to voltage spikes and surges. This makes it an ideal choice for harsh industrial settings and infrastructure critical to energy transition, such as solar inverters and EV charging stations.

ICGOOODFIND: The Infineon IPA90R340C3 is a benchmark in high-voltage power transistor technology. It masterfully combines extremely low conduction losses, fast switching speed, and robust thermal performance, making it an indispensable component for engineers striving to achieve new heights in power density and energy efficiency for their next-generation designs.
