MANUFACTURED BY Littelfuse

The SMBLCE-HR/HRA (600 W), SMCLCE-HR/HRA (1500 W), and SMDLCE-HR/HRA (3000 W) series stand out for their unique combination of high reliability and low capacitance in compact JEDEC DO-214AA and DO-214AB packages. These diodes are meticulously designed, manufactured, and screened to eliminate early failures, ensuring consistent performance without degradation even under continuous surge conditions. With capacitance values as low as 50 pF and power ratings ranging from 600 to 3000 watts, these TVS diodes offer unparalleled protection for sensitive avionics data lines. View the video. The new TVS diodes are ideal for a range of avionics applications, including:

• Flight control systems,

• Full Authority Digital Engine Control (FADEC),

• Radar systems, and

• Other high-speed data interfaces.

By offering exceptional protection against overvoltage threats, these diodes ensure the reliability and safety of critical avionics equipment. “Today’s aircraft designs are increasingly utilizing new composite materials and higher data speeds,” said Charlie Cai, Director of Product Management, Protection Business, Semiconductor Business Unit at Littelfuse. “This trend necessitates a higher level of lightning protection for all electronic equipment and electrical systems. Our new TVS diodes, with enhanced power ratings of 600 to 3000 watts in very compact surface-mount packages, will enable electronics engineers to design equipment that meets the high-grade regulatory requirements for protecting data
