Infineon IPB020N08N5 OptiMOS 5 Power MOSFET: High-Efficiency 80V Performance in a Compact Package

The relentless pursuit of higher efficiency and power density in modern electronics drives the need for advanced power semiconductor solutions. Addressing this challenge, Infineon Technologies introduces the IPB020N08N5, a member of the esteemed OptiMOS™ 5 family, which sets a new benchmark for 80V power MOSFETs. This device is engineered to deliver exceptional switching performance and minimized losses, making it an ideal cornerstone for a wide array of demanding applications.

At the heart of this MOSFET's superiority is its ultra-low figure-of-merit (R DS(on) Q G). With a maximum drain-source on-state resistance of just 2.0 mΩ, the IPB020N08N5 significantly reduces conduction losses. This is complemented by an optimized gate charge, which ensures swift switching transitions and drastically cuts switching losses. This combination is critical for systems operating at high frequencies, where efficiency is paramount. The result is a cooler-running, more reliable system that requires less bulky cooling solutions, thereby reducing overall size and cost.

The component is housed in the space-saving Infineon’s proprietary PG-TDSON-8 (5x6) package. This compact footprint is a key enabler for high power density designs, allowing engineers to pack more power into increasingly constrained spaces without compromising thermal or electrical performance. The package also features an exposed top-side cooling pad, which provides excellent thermal dissipation directly to a heatsink or the PCB, further enhancing its ability to handle high power levels.

The 80V voltage rating of the IPB020N08N5 makes it exceptionally versatile. It is perfectly suited for a broad spectrum of applications, including:

Industrial Power Supplies: High-efficiency SMPS (Switch-Mode Power Supplies) and server PSUs.

Motor Control: Driving brushless DC (BLDC) motors in industrial tools, drones, and light electric vehicles.

Solar Energy Systems: Optimizers and microinverters where high efficiency directly impacts energy harvest.

Battery Management Systems (BMS): For protection circuits in high-power Li-ion battery packs.

ICGOOODFIND: The Infineon IPB020N08N5 OptiMOS 5 80V MOSFET stands out as a premier solution for designers pushing the limits of efficiency and power density. Its industry-leading low R DS(on), exceptional switching characteristics, and thermally enhanced miniature package make it a superior choice for the next generation of high-performance power conversion systems.
