Infineon IPA50R950CE: A High-Performance 950V CoolMOS™ CE Power Transistor
In the realm of high-voltage power conversion, efficiency, robustness, and reliability are paramount. The Infineon IPA50R950CE stands out as a premier solution, engineered to meet the demanding requirements of modern switch-mode power supplies (SMPS), industrial drives, and renewable energy systems. As part of Infineon’s innovative CoolMOS™ CE series, this 950V power transistor leverages superjunction technology to deliver exceptional performance where it matters most.
Unmatched Efficiency with CoolMOS™ Technology
The core of the IPA50R950CE’s superiority lies in its advanced superjunction (SJ) technology. This design drastically reduces on-state resistance (RDS(on)) while minimizing switching losses. The result is a device that operates at higher efficiency levels, even under high-frequency switching conditions. For power supply designers, this translates into reduced heat generation, lower cooling requirements, and the ability to create more compact, energy-efficient systems. The 950V voltage rating provides a comfortable safety margin in 400V line-voltage applications, enhancing system reliability in the face of voltage spikes and transients.
Robustness and Reliability
The IPA50R950CE is built to endure the rigors of industrial environments. It features exceptional avalanche ruggedness and is qualified for 100% repetitive avalanche testing, ensuring it can handle extreme stress conditions without failure. This makes it an ideal choice for applications like server PSUs, telecom bricks, and photovoltaic inverters, where downtime is not an option. The integrated fast body diode further enhances its reliability in hard-switching topologies, such as power factor correction (PFC) circuits, by improving reverse recovery characteristics.
Optimized for Ease of Use
Beyond its electrical performance, the IPA50R950CE is designed for practicality. The TO-220 package is industry-standard, making it easy to implement in both new designs and existing layouts. Infineon has also optimized the gate charge (Qg) of the device, which simplifies gate driving requirements and allows for the use of less complex, more cost-effective driver circuits.
In summary, the Infineon IPA50R950CE is a top-tier 950V MOSFET that sets a high benchmark for performance in power electronics. Its blend of ultra-low losses, high ruggedness, and design flexibility makes it an excellent component for engineers striving to push the boundaries of efficiency and power density. For those developing high-performance systems, this CoolMOS™ CE transistor represents a reliable and highly efficient switching solution.
