Littelfuse Inc announced the launch of the new 5.0SMDJxxS-HRA TVS diode series. These highly reliable TVS diodes have been carefully designed, manufactured and screened to provide a powerful overvoltage protection function, with extremely low early failure rate and zero attenuation in continuous surge events.
Today's aircraft use more new composite materials, which requires all electrical and electronic equipment to have a higher level of lightning protection function. 5.0 SMDJxxS-HRA is a highly reliable TVS diode series developed for the aircraft subsystem to protect sensitive electronic equipment from the impact of voltage transients caused by lightning and other transient voltage events. When manufacturing high reliability TVS diodes, Littelfuse adopted a strict electronic component upgrade screening process to ensure enhanced robustness. They are packaged with 5000W surface mount DO-214AB, with a power density of up to 5 kW.
5.0 SMDJxxS-HRA TVS diode series is suitable for applications requiring high reliability in harsh environments, including aerospace, avionics and aircraft subsystems (such as cockpit display, flight control, radar, etc.), aircraft power transmission system, AC or DC power line protection, low-frequency data line, industrial automation and applications in harsh environments
Charlie Cai, senior product marketing manager of Littelfuse, said: "The 5.0SMDJxxS-HRA TVS diode series has a higher power rating (up to 5KW) and uses the same compact surface mount package (the same as the previous solution) To provide higher electronic protection performance and greater design flexibility. These upgraded TVS diodes can help avionics designers meet stringent and high-level regulatory requirements without increasing the size of printed circuit boards. "
