Infineon IPD80R1K0CE: A High-Performance Power MOSFET for Efficient Switching Applications

The relentless pursuit of higher efficiency and power density in modern electronics places immense demands on power switching components. At the heart of many advanced power conversion systems, from industrial motor drives to switched-mode power supplies (SMPS) and renewable energy inverters, lies the power MOSFET. The Infineon IPD80R1K0CE stands out as a premier component engineered to meet these rigorous challenges, offering a blend of low losses, high robustness, and superior switching performance.

This MOSFET is built on Infineon’s proprietary CoolMOS™ CE technology, a hallmark of innovation in superjunction (SJ) MOSFETs. The core advantage of this technology is its revolutionary trade-off between on-state resistance (RDS(on)) and gate charge (Qg). The IPD80R1K0CE, with a voltage rating of 800V and a remarkably low RDS(on) of just 100mΩ (max. at 25°C), is designed to minimize conduction losses. Simultaneously, its optimized internal cell structure ensures an exceptionally low gate charge, which directly translates to reduced switching losses and lower drive requirements. This combination is critical for achieving high efficiency, particularly in high-frequency switching applications where losses can quickly accumulate and impact overall system thermal performance and size.

Furthermore, the device exhibits excellent switching characteristics, including soft and fast body diode commutation. This feature is vital for applications like power factor correction (PFC) stages, where the body diode's reverse recovery behavior can significantly affect electromagnetic interference (EMI) and efficiency. The robust design of the IPD80R1K0CE also ensures a high degree of avalanche ruggedness and operational reliability, even under harsh conditions or unexpected voltage spikes.

The benefits extend beyond pure electrical performance. The low losses contribute to cooler operation, reducing the burden on thermal management systems and allowing for more compact designs. This makes the MOSFET an ideal choice for designers aiming to push the limits of power density without compromising reliability. Its high-performance credentials are perfectly suited for demanding applications such as server and telecom power supplies, solar microinverters, and welding equipment.

ICGOODFIND: The Infineon IPD80R1K0CE is a top-tier 800V power MOSFET that exemplifies engineering excellence. Its mastery of the crucial RDS(on)-Qg trade-off via CoolMOS™ CE technology makes it an outstanding choice for designers seeking to maximize efficiency, minimize heat generation, and achieve higher power density in their high-frequency switching applications.
