TVS-Diodes

Transient Voltage Suppression (TVS) diodes are semiconductor devices which are used to protect electronic devices from transients such as electrostatic discharge (ESD) and lightning induced surges. TVS diodes are also known as TVSs, transil diodes, or surge suppressors. They are devices which are designed to conduct transient voltages, reduce the peak voltage, and to protect the circuit components from expensive hardware damages caused by surge voltage events.TVS diodes are available in various packages such as surface mount, through-hole, or SMD, and have different values of breakdown voltages according to their application. The most commonly used TVS diode is the PTVS10VS1UR, which is a unidirectional diode having a breakdown voltage of 10V with a peak pulse power of 115W (IEC 61000-4-2, Level 3) under certain specific conditions. The main principle of a TVS diode is that it acts like a resistor in the forward direction until its breakdown voltage is reached. When the breakdown voltage is exceeded, the voltage across the diode increases exponentially leading to its energy dissipating characteristics. This dissipates the transient voltage as heat instead of allowing it to cause damage to the circuit components.There are many applications of TVS diodes such as in ESD protection, lightning protection, automotive applications, overvoltage and overcurrent protection, and protection of power supply lines against surges. TVS diodes are also used in telecommunications equipment, industrial equipment, safety equipment, and consumer electronics products.Due to their low capacitance and low leakage current, TVS diodes are often used as RF protection devices which protect RF cables and components from transient voltages without degrading the RF signal. They are also used in automotive electronics such as airbag controllers, transmission and engine controllers, and ABS systems. The temperature and power rating of TVS diodes should be taken into consideration when selecting the appropriate device for a particular application. Different applications have different requirements like working temperatures, peak power and voltage ratings, and they should all be taken into account when selecting the right TVS diode.TVS diodes are generally meant for transient voltage suppression and they should not be used as permanent solutions to voltage suppression issues. They are used as a temporary measure to suppress and absorb transient currents which cannot be handled by other components of the circuit. They do not provide permanent protection and should be replaced when they have served their purpose.TVS diodes are relatively cheap and are becoming increasingly popular due to their cost effectiveness and their capability to protect delicate electronic devices from transient voltages. With the proper selection and application, they can provide a cost-effective solution to transient voltage suppression.
