    HEXFET MOSFETs

    HEXFET MOSFETs are a type of power MOSFET technology from Infineon Technologies. The name "HEXFET" is derived from the hexagonal cell design used in the structure of these MOSFETs, which optimises the use of silicon area and improves performance. HEXFET MOSFETs are widely recognised for their efficiency, ruggedness, and reliability, making them suitable for a broad range of power management applications.

    HEXFET MOSFETs features include:

    • Low On-Resistance (Rds(on)) which minimises conduction losses and improves overall efficiency.
    • High Current Capability due to the hexagonal cell design
    • Fast Switching Speed - which is essential for high-frequency applications and helps in reducing switching losses.
    • Ruggedness - designed to withstand harsh electrical environments, offering high robustness against voltage spikes and transients.
    • Efficient thermal management, allowing for better heat dissipation and operation at higher temperatures.
    • Ease of Use - these MOSFETs are available in a variety of packages and voltage ratings, making them versatile and easy to integrate into different designs.

    HEXFET MOSFETs Applications:

    • Power Supplies
    • Motor Control
    • Automotive
    • Battery Management
    • Lighting
    • Audio Amplifiers

    HEXFET MOSFETs series include:

    • IRL and IRF Series - known for their wide range of voltage ratings and package options. They are widely used in general-purpose power management and motor control applications.
    • IRLB and IRLZ Series - offer logic-level gate drive capability, making them suitable for applications where the MOSFET is driven directly by microcontrollers or logic circuits.
    • Automotive HEXFETs - designed to meet requirements of automotive applications, including AEC-Q101 qualification for enhanced reliability and robustness.

    HEXFET MOSFETs remain a popular and reliable choice for many applications due to their established design and good balance of features.
