Infineon IPA65R400CEXKSA1 650V CoolMOS™ Power Transistor for High-Efficiency Applications

The continuous evolution of power electronics demands components that deliver superior efficiency, thermal performance, and reliability. Infineon Technologies addresses these needs with the IPA65R400CEXKSA1, a 650V CoolMOS™ Power Transistor engineered specifically for high-efficiency and high-frequency switching applications. This device stands out as a cornerstone technology for next-generation power supply designs, including server and telecom SMPS, industrial power systems, and renewable energy inverters.

Built on Infineon’s advanced superjunction (SJ) technology, the IPA65R400CEXKSA1 offers an exceptional low on-state resistance (RDS(on)) of 0.400 Ω combined with ultra-low gate and output charges. This optimal balance minimizes conduction and switching losses, which are critical for achieving high energy efficiency across various load conditions. The result is reduced heat generation, allowing for more compact designs with lower cooling requirements or higher power density.

The transistor’s 650V voltage rating provides a robust safety margin for operation in universal mains applications (85 – 305 VAC), enhancing system reliability in the face of voltage spikes and transients. Furthermore, its fast switching capability enables power supply designers to push switching frequencies higher, which contributes to the miniaturization of magnetic components like transformers and inductors.

Another key feature is its optimized gate charge (Qg) and capacitance, which simplifies gate driving design, reduces driving losses, and improves immunity against parasitic turn-on. The device is also housed in a TO-220 package, offering a proven and widely used option for efficient thermal management when attached to a heatsink.

In summary, the Infineon IPA65R400CEXKSA1 exemplifies the innovation in power semiconductor technology, providing designers with a highly efficient and reliable solution to meet the increasing demands of modern power conversion systems.
