Surface mount TVS diodes safeguard sensitive automotive electronics

Littelfuse, Inc., the global leader in circuit protection, today introduced a series of AEC-Q101 qualified TVS Diodes designed specifically to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events.

SLD8S Series Automotive SMT Transient Voltage Suppression (TVS) Diodes offer a choice of 7000W (10/1000μs) or 2200W (load dump) peak pulse power dissipation ratings in a surface mount SMTO-263 package. These high peak pulse power dissipation ratings allow power systems to pass the ISO 7637-2 5a, 5b surge tests and meet the ISO 16750-2 load dump waveform standard, which are widely used in the automotive industry as the basis for transient specifications. Their surface mount package is ideal for automatic pick-and-place assembly and reflow processes.

SLD8S Series TVS Diodes are well suited for applications such as load dump protection and ESD protection in automotive electronics like transmission control units (TCUs), electronic control units (ECUs), body control modules (BCMs), battery management systems (BMSs), sensors, and entertainment systems, as well as in other long pulse applications that require high reliability.

“The SLD8S Series is ideal for automotive load dump protection and its surface mount design reduces manufacturing costs and allows for higher soldering quality than axial lead packages,” said Charlie Cai, global product marketing manager at Littelfuse. “Its SMTO-263 package design is footprint-compatible with popular solutions in DO-218AB packages, while offering a wider range of stand-off voltages, up to 57V, so it allows for easy replacement in new circuit designs.”

SLD8S Series Automotive TVS Diodes offer these key benefits:

• Meets ISO7637-2 5a/5b protection and ISO16750 load dump test requirements, making them well suited for load dump protection.
• Features an SMT package that is ideal for automatic pick and place assembly and reflow processes, which helps reduce manufacturing costs and allows for higher soldering quality than axial lead packages.
• Ensures maximum performance in automotive and high-reliability applications due to their AEC-Q101 qualified design and operating junction temperature (T_J) of up to 175°C.

The SLD8S Series (SMTO-263 package) is provided in tape and reel packaging in quantities of 500.
