TE Circuit Protection PolyZen devices are polymer enhanced, precision Zener diode micro-assemblies. They offer resettable protection against multi-Watt fault events without the need for multi-Watt ...

A Zener diode is the simplest known type of voltage limiter (Figure 1) As soon as the voltage exceeds the rated voltage of the Zener diode, a current can flow through the diode to limit the voltage.

In the quest for higher speed and lower costs, today’s modern electronics use increasingly dense integrated circuit technologies, whose sensitivity to surges creates difficult challenges for designers ...
