Infineon IPW60R120C7: A High-Performance 600V CoolMOS Power Transistor

In the realm of power electronics, efficiency, reliability, and thermal performance are paramount. The Infineon IPW60R120C7 stands out as a premier solution, engineered to meet the rigorous demands of modern high-efficiency switched-mode power supplies (SMPS), power factor correction (PFC) stages, and various industrial applications. As a member of Infineon’s renowned CoolMOS™ C7 family, this 600V power MOSFET sets a new benchmark for performance in its class.

The core innovation of the CoolMOS C7 technology lies in its superjunction (SJ) structure. This advanced design drastically reduces the on-state resistance (RDS(on)) for a given silicon area, which is the fundamental key to minimizing conduction losses. The IPW60R120C7 boasts an exceptionally low RDS(on) of just 120 mΩ at a gate-source voltage of 10 V. This low resistance directly translates to higher efficiency, as less energy is wasted as heat during operation.

Beyond low conduction losses, switching performance is critical for high-frequency operation. The IPW60R120C7 is optimized for fast switching, which allows power supply designers to increase the switching frequency of their designs. This, in turn, enables the use of smaller passive components like inductors and transformers, leading to more compact and lighter end products. The transistor exhibits low gate charge (QG) and low effective output capacitance (COEr), which are essential parameters for reducing switching losses and achieving high efficiency at elevated frequencies.

Thermal management is a significant challenge in power-dense designs. The low thermal resistance of the package, coupled with the high efficiency of the device itself, ensures that heat is effectively dissipated. This robust thermal performance enhances the overall reliability and longevity of the system, allowing it to operate continuously under heavy load conditions without premature failure.

The IPW60R120C7 is particularly suited for demanding applications such as:

Server and telecom SMPS

Industrial power supplies

Solar inverters and energy storage systems

High-power LED lighting drivers

Automotive charging infrastructure

Its ability to operate efficiently at high frequencies makes it an ideal choice for the latest generations of power converters striving to meet stringent global energy efficiency regulations like 80 PLUS Titanium.
