Infineon IRFS7440TRLPBF: High-Performance 60V HEXFET Power MOSFET

In the realm of power electronics, efficiency, reliability, and thermal performance are paramount. The Infineon IRFS7440TRLPBF stands out as a premier solution, engineered to meet the rigorous demands of modern switching applications. This 60V HEXFET Power MOSFET incorporates advanced silicon technology, offering an exceptional balance of low on-state resistance and high switching speed.

A key highlight of this MOSFET is its extremely low typical RDS(on) of just 1.8 mΩ at 10 V. This ultra-low resistance directly translates to minimized conduction losses, enabling higher efficiency and reduced heat generation in applications such as synchronous rectification in switch-mode power supplies (SMPS), motor control, and DC-DC converters. The device is housed in a robust D2PAK (TO-263) package, which provides superior thermal characteristics, allowing it to handle a continuous drain current (ID) of 195 A at 25°C. This makes it exceptionally suitable for high-current environments.

Furthermore, the IRFS7440TRLPBF is designed with optimized switching performance. The low gate charge (QG) and Miller charge (QGD) ensure fast switching transitions, which are critical for high-frequency operation. This leads to reduced switching losses and allows for the design of more compact and efficient power systems. The device also features a low thermal resistance junction-to-case (RthJC) of 0.45 °C/W, facilitating effective heat dissipation and enhancing overall system reliability under heavy load conditions.

ICGOOODFIND: The Infineon IRFS7440TRLPBF is a top-tier 60V power MOSFET that excels in delivering high efficiency, robust thermal management, and superior current handling, making it an ideal choice for demanding power conversion tasks.
