IRFH8202TRPBF: A High-Performance Power MOSFET for Advanced Switching Applications

The relentless pursuit of higher efficiency and power density in modern electronics drives the continuous innovation in power semiconductor technology. At the forefront of this evolution is the IRFH8202TRPBF, a state-of-the-art power MOSFET engineered to excel in demanding switching applications. This device encapsulates advanced silicon and packaging technology, offering system designers a potent solution for overcoming challenges in power conversion and management.

Engineered with a robust silicon design, the IRFH8202TRPBF is built on Infineon's proprietary high-performance process. It features an exceptionally low typical on-resistance (RDS(on)) of just 1.8 mΩ at a 10V gate drive. This ultra-low resistance is a critical figure of merit, as it directly translates to minimized conduction losses during operation. When a MOSFET is in its on-state, the primary source of power loss is the I²R dissipation across its drain-to-source path. By drastically reducing RDS(on), the IRFH8202TRPBF ensures that more energy is delivered to the load and less is wasted as heat, significantly boosting overall system efficiency.

Beyond its impressive static performance, this MOSFET is optimized for dynamic switching. Its gate charge (Qg) and figure of merit (FOM, or RDS(on) Qg) are meticulously balanced. This results in rapid switching transitions, which are essential for high-frequency operation in switch-mode power supplies (SMPS), DC-DC converters, and motor drive circuits. Faster switching allows for the use of smaller passive components like inductors and capacitors, directly contributing to increased power density and reduced system size and cost. Furthermore, the device boasts excellent body diode robustness, enhancing its reliability in hard-switching and synchronous rectification topologies where the intrinsic diode is forced to conduct.

The "TRPBF" suffix denotes that the component is supplied in a tape-and-reel format and is compliant with the Restriction of Hazardous Substances (RoHS) directive. It is housed in the industry-standard PQFN 5x6 mm package, which offers a compact footprint and a very low profile. This package is designed for superior thermal performance, featuring an exposed pad that efficiently transfers heat from the silicon die to the printed circuit board (PCB). This effective thermal management is paramount for maintaining device reliability under high-stress conditions, allowing it to handle a continuous drain current (ID) of 140A and survive high pulse currents.

Typical applications that benefit from the capabilities of the IRFH8202TRPBF include:

High-current synchronous rectification in server and telecom power supplies.

Primary switching in high-frequency DC-DC buck and boost converters.

Motor control and drive circuits in industrial automation and automotive systems.

OR-ing FET and load switch solutions in power distribution.
