- Advertisement -

The first-to-market asymmetrical TVS solution made especially to shield Silicon Carbide (SiC) MOSFET gates from overvoltage situations is the SMFA Asymmetrical Series Surface-Mount TVS Diode, which Littelfuse announced.Littelfuse TVS Diode SMFA Asymmetrical Series SiC MOSFET The Volt post

Robust gate protection is more important than ever as SiC MOSFETs gain popularity because of their quicker switching times and higher efficiency when compared to conventional Silicon MOSFETs and IGBTs. An inventive single-component approach that greatly improves circuit dependability while streamlining design is provided by the SMFA Asymmetrical Series.

The only TVS diode designed especially to meet the special gate protection needs of SiC MOSFETs is the SMFA Asymmetrical Series.

The SMFA Series efficiently prevents ringing and overshoot phenomena in gate drive circuits with a single component, conserving important PCB space and simplifying circuit designs in contrast to conventional solutions that call for many Zener or TVS diodes.

The SMFA Asymmetrical Series Surface-Mount TVS Diode Offers the Following Key Features and Benefits:

  • Asymmetrical Design: The SMFA Series is tailored to the specific negative and positive gate voltage ratings of SiC MOSFETs, ensuring precise and reliable protection.
  • Single-Component Solution: Replaces multiple Zener and TVS diodes, reducing the number of components and simplifying circuit layout.
  • Space Efficiency: By combining multiple protection functions into one component, the SMFA Series minimizes PCB space usage, allowing for more compact and efficient designs.
  • Compatibility: The SMFA Asymmetrical Series is compatible with all available Littelfuse and other leading SiC MOSFETs, making it a versatile solution for various applications.

The SMFA Asymmetrical Series is ideal for a variety of demanding applications where SiC MOSFETs are used, including:

  • AI / Data Center Server Power Supplies: Enhances the reliability and efficiency of critical power supplies in high-performance computing environments.
  • High-Efficiency Electric Vehicle Infrastructure (EVI) Power Systems: Provides robust gate protection in EV charging stations and related power systems, ensuring longevity and performance.
  • High-Reliability Semiconductor/Industrial Equipment Power Supplies: Protects essential power supplies in industrial and semiconductor manufacturing environments, where reliability and uptime are paramount.
