TVS - Diodes Application Field and Working Principle

TVS (Transient Voltage Suppressors) diodes are an effective way of protecting sensitive electronic components from dangerously high voltages such as electrostatic discharge (ESD), AC surges, and other transients. They are most commonly used in power supplies, communication systems, automotive electronics, consumer electronics, and medical devices.TVS diodes work by quickly conducting excess voltage to ground as soon as it exceeds the breakdown voltage of the component. Depending on the type of diode, there are different ways it conducts the voltage. For example, the 3KP9.0A-B TVS diode helps protect against voltage spikes up to 600V and has an operating voltage range of 11-42V. It can protect two lines with differential mode protection and has a reverse leakage current of less than 1µA at 55°C.The three main types of TVS diode are unidirectional, bidirectional, and zener diodes. Unidirectional diodes are designed to protect only one circuit and have two terminals, an anode, and a cathode. They are also known as “crowbar” diodes because of their shape, which is close to the familiar shape of a crowbar. Bidirectional diodes provide protection for both sides of a circuit and have three terminals, an anode, a cathode, and a grounding point. Zener diodes are designed for higher-energy surges and have two terminals, an anode and a cathode.When choosing a TVS diode, it is important to consider the peak voltage, reverse leakage, surge current, and capacitance of the device. The peak voltage rating of the device should be as close to the expected surge voltage as possible without exceeding it. It is also important to choose a device with a low reverse leakage rating to ensure that the device does not leak any current when the circuit is not activated. The surge current rating should also be high enough to handle the expected transient current surge, while the capacitance should be low enough to limit the effects of noise in the signal.In conclusion, TVS diodes, such as the 3KP9.0A-B offer a reliable and effective way of protecting electronic components from dangerous voltage transients. They are available in three main types, unidirectional, bidirectional, and zener diodes with different characteristics that can be suited to a variety of applications. When selecting a TVS diode, it is important to consider the peak voltage rating, reverse leakage, surge current, and capacitance to ensure that it is suited to the application.
