Qualified surface mount TVS diodes safeguard sensitive automotive electronics

Littelfuse has 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. The SLD8S Series automotive SMT 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. The TVS diodes are well suited for applications such as load dump protection and ESD protection in automotive electronics like transmission control units, electronic control units, body control modules (BCMs), battery management systems, 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.”
