The 5.0SMDJxxS-HRA TVS Diode Series is designed, manufactured, and screened to provide robust overvoltage protection with low early failures and zero degradation over continuous surge events.
Today's aircraft use more and new composite materials, thus requiring higher-level lightning protection for all electrical and electronic equipment. The 5.0SMDJxxS-HRA is a highly reliable TVS diode series developed for aircraft subsystems. They protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Littelfuse manufactures these high-reliability TVS diodes using a stringent process for up-screening electronic components that ensures enhanced robustness. They are available in a 5,000-W surface-mount DO-214AB package with a high power density of up to 5 kW.
The 5.0SMDJxxS-HRA TVS Diode Series is ideal for applications that require high reliability under harsh environments, including:
 • Aerospace, avionics, and aircraft subsystems (e.g., cockpit displays, fight control, radar, etc.),
 • Aircraft power trains;
 • AC or DC power line protection;
 • Low-frequency data lines;
 • Industrial automation; and
 • Harsh environment applications.
"The 5.0SMDJxxS-HRA TVS Diode Series enhanced power rating [up to 5 KW] while in the same compact surface-mount package [as prior solutions] provide increased electronics protection performance and greater design flexibility," said Charlie Cai, a senior product marketing manager at Littelfuse. "These up-screened TVS diodes help aerospace electronics designers meet demanding high-grade regulatory requirements without needing to increase the size of their printed circuit boards."
