What is a TVS - Diodes?

TVS diode is a unique type of semiconductor device used to protect sensitive electronic circuits from voltage transients caused by electrostatic discharge (ESD), electrical fast transients (EFT), or lightning. They are also known as transil diodes, transversal voltage suppression diodes. The TVS diode is composed of a series of junctions that are configured in such a way that they can absorb and dissipate sudden voltage transients caused by ESD before they can damage the protected component.

VS3V3BB1EST15R application field and working principle

VS3V3BB1EST15R is a transil diode designed specifically for automotive applications, ranging from 12V to 24V systems. It has an ultra-low reverse blocking voltage of 3.3V that can protect sensitive electronics and highly-integrated automotive systems from destructive voltage transients and electrostatic discharge (ESD) damage. The device features an extremely low leakage current of less than 5nA and a low clamping voltage of 17.2V. The working principle of the VS3V3BB1EST15R is based on the basic p-n junction diode. When a transient voltage is applied to the diode, it quickly moves the current flow through the device and provides an alternate path for the current (called clamping action). This reduces the voltage seen by the protected electronic components, preventing any damage to the system. When the transient voltage has been dissipated, the diode returns to its normal low impedance state, allowing normal circuit operation to be resumed. The VS3V3BB1EST15R is typically used in automotive electronics and industrial-related applications. It can be used to protect systems from voltage transients, ESD and EMI that can damage sensitive components and cause premature system failure. It can also be used in voltage rail applications, such as memory and logic buses, to protect them from sudden voltage transients. Thanks to its very low surge response time and clamping voltage, the VS3V3BB1EST15R is an excellent solution for protecting sensitive electronics in extreme conditions. Additionally, its low leakage current makes it ideal for conserving energy and maximizing system efficiency.
