Infineon IPL60R160CFD7 600V CoolMOS™ CFD7 Power Transistor: Performance and Applications

The relentless pursuit of higher efficiency, power density, and reliability in power electronics drives continuous innovation in semiconductor technology. At the forefront of this evolution is Infineon's CoolMOS™ CFD7 series, with the IPL60R160CFD7 standing out as a prime example of a high-performance 600V superjunction (SJ) MOSFET engineered for demanding applications. This device masterfully balances ultra-low switching losses with exceptional ease of use, setting a new benchmark for power conversion systems.

Unpacking the Performance Edge: Key Features

The IPL60R160CFD7 is built on Infineon's revolutionary CoolMOS™ CFD7 technology, which incorporates a fast body diode and an integrated voltage source for advanced controllability. Its standout specification is an ultra-low on-state resistance (R DS(on)) of just 160mΩ, which directly translates to minimized conduction losses. This is particularly beneficial in continuous operation modes, leading to cooler running temperatures and higher overall system efficiency.

Beyond static performance, the device excels in dynamic operation. The fast and robust intrinsic body diode is a hallmark of the CFD7 family. This feature drastically reduces reverse recovery charge (Qrr) and eliminates the need for an external anti-parallel diode in many topologies. The result is a significant reduction in switching losses, especially in hard- and soft-switching applications like power factor correction (PFC) circuits. Furthermore, the technology provides enhanced dv/dt controllability, offering designers greater flexibility in managing switching speed to optimize the electromagnetic interference (EMI) performance of their systems without sacrificing efficiency.

Target Applications: Where It Excels

The unique combination of low switching and conduction losses makes the IPL60R160CFD7 an ideal choice for a wide array of high-efficiency power supplies. Key application areas include:

Server, Telecom, and Industrial SMPS: Its ability to operate efficiently at high switching frequencies allows for the design of smaller, more power-dense AC-DC power supplies and DC-DC converters.

Power Factor Correction (PFC): The robust fast body diode makes it a superior choice for totem-pole PFC stages, which are essential for achieving ultra-high efficiency (e.g., 80 PLUS Titanium standards) in modern server and communication infrastructure.

Solar Inverters and Energy Storage Systems (ESS): In renewable energy applications, high efficiency and reliability are paramount. This MOSFET helps minimize energy loss in boost converters and inverter stages.

Lighting: The technology is well-suited for high-end LED lighting drivers that require compact form factors and high efficiency.

Motor Control and Drives: It can be effectively used in inverter stages for various motor control applications, benefiting from its low losses and robust switching characteristics.

ICGOOODFIND: The Infineon IPL60R160CFD7 CoolMOS™ CFD7 is a pinnacle of power transistor design, offering a near-perfect synergy of minimized switching losses, a robust integrated body diode, and excellent controllability. It is a transformative component that empowers engineers to push the boundaries of efficiency and power density in next-generation switch-mode power supplies, renewable energy systems, and industrial drives.
