The SLD8S TVS automotive series from Littelfuse meets ISO7637-2 5a/5b protection and ISO16750 load dump test. It offers a choice of peak pulse power dissipation ratings. SLD8S Series Automotive SMT Transient Voltage Suppression (TVS) Diodes from Littelfuse 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 enable power systems to pass the ISO test standards that 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.

Applications include load dump protection and ESD protection in automotive electronics like ECUs, TCUs, BCMs, BMSs, sensors, and entertainment systems, as well as in other long pulse applications that require high reliability.
