TDK Corporation’s new voltage protection device— Multilayer varistors with high ESD robustness

A leading electronics company, TDK Corporation in a move to expand its product lineup has launched new type of multilayer varistor— AVRH10C221KT1R5YA8 for automotive Ethernet with a very high ESD robustness for use in hostile environments.

The new addition to the AVR series provides reliable ESD protection up to 25 kv (IEC61000-4-2). Moreover, the new chip varistor features a low capacitance of 1.5 ± 0.13 pF. With its IEC 1005 package (1.0 x 0.5 x 0.5 mm) the component’s volume is about 75 per cent smaller than that of existing components. The new varistor features a maximum operating voltage of 70 v and an operating temperature range of -55 to 150 °C. Thus, enabling a broad range of possible applications.

Automotive Ethernet is the communication infrastructure of choice for today’s vehicles since ECUs require a high speed, low latency communication in advanced driver assistance systems (ADAS) and autonomous driving. TDK’s newest multilayer varistor extends the portfolio of protection components for automotive Ethernet applications. With the AVR and CT series reliable ESD protection up to 25 kV is now available for both 100Base-T1 and 1000Base-T1 interfaces without impeding high speed data communication.

Moving forward, TDK plans to further increase the product lineup in terms of compactness, operating voltage, and capacitance to flexibly respond to the wide range of automotive device designs.
