SMD TVS diodes provides high reliability for aerospace and avionics applications

Littelfuse, Inc has released a new 5.0SMDJxxS-HRA TVS Diode Series. The high-reliability TVS diodes are developed, manufactured, and screened to offer robust overvoltage protection, with low early failures and zero degradation over continuous surge events.

Today's aircraft employ more and new composite materials, therefore, needing higher-level lightning protection for all electrical and electronic equipment. The series is a highly reliable TVS diode series produced for aircraft subsystems, and they shield sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The company fabricates these high-reliability TVS diodes employing a stringent process for up-screening electronic components that provides enhanced robustness. They are offered in a 5000W surface-mount DO-214AB package with a high-power density of up to 5kW.

The series is ideal for applications that need 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 5kW) while in the same compact surface-mount package (as prior solutions) provide increased electronics protection performance and greater design flexibility," said Charlie Cai, 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."
