TVS (transient voltage suppressor) diodes are a type of semiconductor electronics designed to protect semiconductor electrical devices and systems from transients, otherwise known as “noise,” which are abnormally high electrical voltages. The ATV15C161J-HF is an example of a TVS diode, designed to protect circuits and equipment from high voltage transients in industrial and automotive applications. Here, we will discuss its application fields, as well as principles of operation.

There are three primary application fields in which the ATV15C161J-HF is used. The first is in automotive applications. It is designed to protect cables, electronics, switches, and other electrical components from damage and distortion caused by spikes and transients in the voltage supply. This protection is especially important for modern electronic control units (ECUs) which need to function properly in order to maintain vehicle performance and safety.

The second application of the ATV15C161J-HF is in industrial applications. This diode is often used to protect sensitive electronics in factories and manufacturing plants from voltage surges caused by machinery operations and other sources. Furthermore, its compact size makes it an ideal solution for applications with limited space, such as consoles and script controllers, where normal transient suppressor devices cannot be used.

Finally, the ATV15C161J-HF is used in communication systems and data processing networks. In these instances, it helps to protect data lines from interference and other distortion sources, ensuring that transmitted data is not lost or corrupted.

In order to better understand the application fields and principles of operation of the ATV15C161J-HF, let’s take a closer look at its structure. The diode comprises of two parts, a silicon body and a metal terminal. The silicon body is further composed of a highly doped P-silicon substrate and a gate oxide layer, which provides the electrical insulation between the active circuit and the substrate. The metal terminal is connected to the silicon body and is used to apply a chemical passivation, which ensures that the characteristics of the diode remain stable over time.

The working principle of the ATV15C161J-HF is based on avalanche breakdown. When an excessive voltage (i.e., a transient) is applied to the diode, the highly doped P-silicon substrate experiences an increase in temperature. This increase generates a high electron current, which in turn causes avalanching. This, in turn, reduces the voltage applied to the P-silicon substrate and protects the circuit or device from damage or distortion.

The ATV15C161J-HF is designed to protect circuits and devices from high voltage transients. It has three primary application fields: automotive, industrial, and communication systems/data processing networks. Its working principle is based on avalanche breakdown, in which a high electron current is induced when the P-silicon substrate of the diode reaches a certain temperature. This reduces the applied voltage and protects the circuit or device from damage or distortion.
