Reliable overvoltage protection for automotive applications

EPCOS CTVS (ceramic transient voltage suppressors) protection devices, from TDK, are based on ceramic multilayer technology. They series is available now from TTI Europe. The series provides reliable overvoltage protection for automotive electronic applications. In addition, the SMD multilayer varistors are also available as special types with defined capacitances, as array types with matched capacitances and as components for increased transient energy. As the networks in cars become increasingly complex with sensors, actuators and control units for advanced assistant systems and data connectivity, they must be properly protected against both ESD and EMI. At the same time, more and more electronic subsystems are directly connected to the vehicle power circuit and therefore exposed to overvoltage transients along the battery lines. The series features components both for reliable ESD protection as well as transient protection in automotive battery lines. The series is qualified based on AEC-Q200. The rugged design and innovative glass coating of the components ensure reliable operation up to 150C and sets a new benchmark for robustness and performance in automotive applications.
