Infineon IPD60R650CE: A 650V CoolMOS™ CE Power Transistor for High-Efficiency Applications

The relentless pursuit of higher efficiency and power density in modern electronics drives the need for advanced power switching components. At the forefront of this innovation is Infineon Technologies with its CoolMOS™ CE series, a technology that has set new benchmarks in performance. The IPD60R650CE stands as a prime example, a 650V superjunction MOSFET engineered to deliver exceptional efficiency in a wide array of applications.

This transistor is specifically designed to minimize energy loss. Its key metric, the figure-of-merit (R DS(on) x Q G), is exceptionally low. This translates into significantly reduced conduction and switching losses, which are the primary sources of inefficiency in power conversion systems. Whether operating in hard-switching or soft-switching topologies, the IPD60R650CE ensures that more energy is delivered to the load and less is wasted as heat.

The benefits of this performance are immediately tangible for designers. Reduced power losses allow for the creation of smaller, more compact power supplies and converters, as less heat sinking is required. This directly contributes to higher power density. Furthermore, the improved efficiency leads to cooler running systems, which enhances overall reliability and longevity. The 650V drain-source voltage rating provides a robust safety margin and makes it highly suitable for mains-powered applications, including those with demanding conditions like industrial motor drives or telecom power systems.

A major advantage of the CoolMOS™ CE technology is its ease of use. The device features integrated fast body diode with excellent reverse recovery characteristics. This is crucial for mitigating voltage spikes and oscillations in circuits like power factor correction (PFC) and LLC resonant converters, simplifying design and improving electromagnetic compatibility (EMC).

Typical applications where the IPD60R650CE excels include:

Switch-Mode Power Supplies (SMPS)

Server and Data Center Power Units

Industrial Power Supplies

Power Factor Correction (PFC) stages

Lighting and Solar Inverter systems
