TVS-Diodes, otherwise known as Transient Voltage Suppressors (TVS) are components utilized in a variety of applications to protect sensitive circuitry from high voltage transients, electrostatic discharge or other potentially damaging events. One example of these components is the TV15C780JB-HF, a TVS diode designed to protect electronic devices and circuits from destructive high-voltage transients. This article will provide an overview of the application field of the TV15C780JB-HF as well as its general working principle.

The TV15C780JB-HF is a multi-directional, low capacitance TVS that is specifically designed to protect high-speed signal lines from extreme transients such as electrostatic discharge (ESD). This component is suitable for use in a variety of applications where high reliability and ruggedness are required, including computers, instrumentation, consumer electronics and industrial equipment. Additionally, this TVS diode features a peak pulse power rating of 6,000 W, an operating voltage up to +125V, and a low clamping voltage of 14V in the IEC 61000-4-2 ESD standard.

In general, TVS diodes are voltage-sensitive semiconductor devices that are designed to protect sensitive electronics from high-voltage transients, ESD or other potentially damaging electrical events. When subjected to an overvoltage, the TVS diode behaves like any other diode, allowing current to flow from one side of the diode to the other. However, once the voltage exceeds the diode’s breakdown voltage, known as the clamping voltage, a low resistance conductive path appears, which diverts the surge energy away from the device and provides an alternate current path. This prevents the destruction of the sensitive electronics due to excessive current.

The TV15C780JB-HF utilizes this same general principle to protect sensitive electronics from overvoltage events. When subjected to an overvoltage, the TVS will limit the voltage to its clamping voltage, meaning it will not exceed a certain level. This clamping voltage can be set to whatever level is required for the application, making it suitable for a variety of applications where different voltage levels are needed. The TV15C780JB-HF has a clamping voltage of 14V, which is suitable for many applications.

In conclusion, the TV15C780JB-HF is an example of a TVS diode designed for use in a variety of applications, including computers, instrumentation and industrial equipment. It features a peak pulse power rating of 6,000 W, an operating voltage up to +125V, and a low clamping voltage of 14V in the IEC 61000-4-2 ESD standard. This diode utilizes the general principle of TVS diodes, which is to limit the voltage to its breakdown voltage, thereby protecting electronic devices and circuits from overvoltage events.
