Infineon IPA80R280P7: A High-Performance Power MOSFET for Efficient Switching Applications

The relentless pursuit of higher efficiency and power density in modern electronics places immense demands on power switching components. At the forefront of this evolution is the Infineon IPA80R280P7, a state-of-the-art Power MOSFET engineered to excel in demanding switching applications. This device combines advanced silicon technology with robust packaging to deliver superior performance, making it an ideal choice for designers of switch-mode power supplies (SMPS), motor control circuits, and power conversion systems.

A key highlight of the IPA80R280P7 is its exceptionally low on-state resistance (RDS(on)) of just 0.28 Ω. This critical parameter is fundamental to minimizing conduction losses when the transistor is fully switched on. By reducing the RDS(on), the MOSFET dissipates less power as heat, leading to significantly higher overall system efficiency and cooler operation. This allows for the design of more compact systems, as the need for large heat sinks is diminished.

Furthermore, this MOSFET is characterized by its outstanding switching performance. Built on Infineon’s proprietary SuperJunction technology, it offers low gate charge (Qg) and low effective output capacitance (Coss(eff)). These parameters are crucial for achieving fast switching transitions, which directly reduces switching losses—a dominant source of inefficiency in high-frequency circuits. The result is the ability to operate at higher frequencies, which in turn enables the use of smaller passive components like inductors and transformers.

The TO-220 FullPAK package provides another layer of reliability. This fully molded package offers robust isolation between the mounting tab and the die, achieving a high isolation voltage. This enhances safety and simplifies mechanical assembly by eliminating the need for an additional insulation kit, thereby improving reliability and reducing the total bill of materials.

Robustness is also a core feature of the IPA80R280P7. It boasts an excellent avalanche ruggedness and a high maximum drain current, ensuring reliable operation even under stressful conditions such as inductive load switching and voltage spikes. This makes it exceptionally durable in industrial environments.

ICGOOODFIND: The Infineon IPA80R280P7 stands out as a premier component for engineers seeking to optimize power conversion stages. Its winning combination of ultra-low RDS(on), fast switching capabilities, and a rugged, isolated package makes it a top-tier solution for achieving new levels of efficiency and power density in applications ranging from server PSUs to industrial motor drives.
