Infineon IPL65R165CFD: A 165mΩ OptiMOS 5 Power MOSFET for High-Efficiency Applications

The relentless pursuit of higher efficiency and power density in modern electronics places immense demands on power switching components. Addressing this challenge, Infineon Technologies has introduced the IPL65R165CFD, a standout member of its advanced OptiMOS™ 5 power MOSFET family. This device, with its ultra-low 165mΩ maximum on-state resistance (R DS(on)), is engineered to minimize conduction losses and set a new benchmark for performance in a compact package.

At the heart of this MOSFET's superiority is the OptiMOS 5 technology platform. This latest generation of superjunction (SJ) MOSFETs leverages Infineon's expertise in process technology and cell design to achieve a remarkable reduction in key loss parameters. The extremely low R DS(on) of just 165mΩ is pivotal, as it directly translates to reduced I²R losses when the device is conducting. This is especially critical in high-current applications, where even a small decrease in resistance can lead to significant gains in system efficiency and a reduction in heat generation, thereby simplifying thermal management.

The device is housed in the space-efficient TOLL (TO-Leadless) package, which offers an excellent footprint-to-performance ratio. This package features a low parasitic inductance and improved thermal performance compared to traditional packages like the D2PAK. The bottom-side cooling capability allows for efficient heat transfer directly to the PCB, making it ideal for high-power-density designs where board space is at a premium. Furthermore, the IPL65R165CFD boasts a high peak current capability, supporting demanding transient conditions commonly found in motor drives and power tools.

These characteristics make the IPL65R165CFD exceptionally well-suited for a wide array of high-efficiency applications. It is a prime candidate for:

Synchronous Rectification in switched-mode power supplies (SMPS) and server power units.

DC-DC Converters in telecom and computing infrastructure.

Motor Control circuits for industrial drives and automotive systems.

Battery Management Systems (BMS) and load switches, where minimizing voltage drop is essential.

ICGOODFIND: The Infineon IPL65R165CFD exemplifies the progress in power semiconductor technology, combining an ultra-low 165mΩ R DS(on) with the thermal and switching advantages of the TOLL package. It is a cornerstone component for engineers aiming to push the boundaries of efficiency and power density in their next-generation designs.
