AEC-Q101 TVS Diode with Greater Protection in Same Footprint

Littelfuse, Inc. has introduced the SLD Series TVS Diode for automotive and high reliability applications. This AEC-Q101 qualified TVS Diode is designed specifically to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. It offers a 5000W (10/1000µs) or 2200W (load dump) peak pulse power dissipation rating in a standard P600 package. The SLD Series' combination of compact design and superior electrical performance offer circuit designers the freedom to upgrade their circuit protection in their existing design footprint or provide more robust load dump protection for new projects.

Applications for SLD Series TVS Diodes include DC power protection and ESD protection in automotive electronics like ECU, TCU, BCM, sensors and entertainment systems, as well as in other long pulse applications that require high reliability.

“The new SLD Series TVS Diode is AEC-Q101 qualified, which makes it very well suited for high reliability applications. It offers peak pulse power dissipation ratings that are ideal for automotive applications,” said Charlie Cai, global product manager of the Automotive TVS Diode product line. “It helps automotive power systems to pass the 5a and 5b surge tests operationally as specified by ISO7637-2 and ISO16750. These standards are widely used in the automotive industry as the basis for transient specifications.”

The SLD Series TVS Diode offers these key benefits: Meets international standards of the automotive industry, which makes it ideal for protective sensitive automotive systems from load dump and other transient voltage events; AEC-Q101 qualified with a junction temperature (Tj ) up to 175°C ensures maximum reliability in automotive and high reliability applications; Compact footprint of the industry-standard P600 package allow quick and easy layout in high reliability applications; and Both uni-directional and bi-directional polarity devices offer from 10V to 60V standoff voltage, fulfilling all design requirements for automotive applications. The SLD Series TVS Diode is available in quantities of 800 (tape and reel packaging) and 100 (bulk packaging).
