Mixed technology Transient Voltage Suppressors (TVSs) are complex devices, able to combine two different technologies into one package. At their core, these TVSs are a combination of both Silicon Avalanche Diodes (SADs) and Gas Discharge Tubes (GDTs) to produce superior performance over any one technology alone. Among the most common of these hybrid TVSs recognized under the acronym ZEN is the ZEN056V260A16YC. This particular model features a voltage rating of 560V with a maximum clamping voltage of 263V, and can handle continuous current of 16A.

The primary application for the ZEN056V260A16YC is to protect circuits from surge voltages of electrical origin, such as those from lightning, static charge, and inductive overloading, which may enter an integrated circuit from the power supply or other external sources. As a mixed technology device, it combines the breakdown thresholds of the SAD with the switching characteristics of a GDT to provide superior protection from damaging transients. In addition to protection from electrical transients, the ZEN056V260A16YC is also designed to reduce EMI emissions and to filter out noise from the power supply.

The ZEN056V260A16YC’s protective performance is a result of its working principle. When the voltage of an external transient exceeds its rated voltage, the device is designed to absorb the current flowing through it and divert it away from the protected circuit. This is done by the SADs, which can switch on at lower voltages than a GDT, and are able to absorb the energy of a surge without causing damage to the protected circuit. When the voltage of the surge exceeds the voltage rating of the SADs, the GDTs are additionally triggered to provide superior protection from an even larger surge.

The ZEN056V260A16YC is a type of mixed technology Transient Voltage Suppressor (TVS) designed for protecting power supplies and other circuits from major voltage transients and surges. Its robust combination of Silicon Avalanche Diodes (SADs) and Gas Discharge Tubes (GDTs) provides superior protection from electrical transients and noise, enabling circuits to operate more reliably and with fewer problems. As such, the ZEN056V260A16YC has become an increasingly popular choice for applications requiring accurate and reliable over-voltage and over-current protection.
