Automotive TVS Diodes

Littelfuse AEC-Q101 Qualified TVS Diodes protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. These AEC-Q101 qualified devices offer peak pulse power dissipation ratings of 400W (SZ1SMA) to 3000W (TPSMD). Littelfuse AEC-Q101 Qualified TVS Diodes are ideal for applications such as DC power protection and ESD protection in automotive electronics such as electronic control units, sensors, and entertainment systems, as well as in portable devices that require high reliability.
