Littelfuse has introduced six new series of high-reliability TVS diodes that have been screened for aerospace applications. 5KP / 15KPA / 30KPA-HR and 5KP / 15KPA / 30KPA-HRA series of high reliability TVS diodes are designed to protect sensitive electronic equipment from transient voltage caused by lightning surges and other transient voltage events. They are specially screened and classified for DC line protection in applications requiring high reliability.
New TVS diodes are highly suitable for robust DC power protection and ESD protection, and are designed for avionics (aviation) applications such as FADEC, aircraft sensors, avionics computers, wire-by-wire flight control systems, cockpit electronics and aircraft landing . Aid system. Other uses include industrial applications, such as the energy industry. In addition to these off-the-shelf components, Littelfuse provides these products with customizable upward screening and classification process solutions to meet the specific requirements of aerospace, defense, industrial and medical applications.
"Not long ago, anyone who needed to screen specific criteria for high-reliability TVS diodes had to ship commercial-grade components to an outsourcer's laboratory for an extra sorting process. Extra steps meant more lead time Long, component costs are greatly increased, "said Charlie Cai, global product manager for high reliability and automotive TVS Diodes. "Now, Littelfuse offers off-the-shelf, screened products and processes that can be customized to customer requirements, and they can get the parts they need faster and more economically."
Customizable for -HR and -HRA series The upward screening / sorting process includes: visual monitor in process, single wafer batch source, high temperature storage life, X-ray inspection, reflow (2X), temperature cycle test, 3 sigma and dynamic test, custom Vbr / lr, additional sorting, HTRB, H3TRB, good traceability and marking. The company states that only the –HR series equipment has been tested in Group B.
