TVS - Diodes

A TVS diode is a type of diode designed to protect sensitive electronic components from being damaged by exposure to voltages that are too high, usually from being connected to power lines. For example, a TVS diode is often used in a home theater system where it can prevent any voltage surges that may occur, as this can damage the system. The device works by clamping the voltage to a safe level so that it does not overheat the electronics or damage them in any way.The most common type of TVS diode is the unidirectional Surge Suppressor, also known as a uni polarity or uni axial TVS diode. This device is used to protect electronic systems from transient voltage and current spikes that can occur during events such as power outages or lightning strikes.The 1SMB170AT3G TVS diode is an example of a unidirectional Surge Suppressor. It is designed to protect sensitive electronic components from voltages that exceed a certain level, by providing a current path to ground when the voltage exceeds the diodes\' breakdown voltage. This type of TVS diode is often used in power supplies as it is capable of handling high current surges associated with lightning and power outages.The working principle of the 1SMB170AT3G TVS diode is quite simple. When the applied voltage or current is below the breakdown voltage of the diode, no current is able to pass through and the circuit remains closed. However, when the voltage or current exceeds the breakdown voltage, the diode acts like a valve, allowing the current to flow and grounding it, thus preventing it from affecting any of the other components in the system.The 1SMB170AT3G TVS diode is especially useful in applications where the input voltages are expected to vary significantly. Its ability to absorb large amount of voltage spikes makes it ideal for use in places where power outages are common, such as in industrial settings or in some rural areas. This type of diode is also popular in cars and other automotive systems, testing equipment, radio systems, and audio systems.In conclusion, the 1SMB170AT3G TVS diode is an important component for protecting sensitive electronic components from the effects of transient voltage surges. Its clamping action allows it to protect components from voltages that would normally cause them to fail, and its unidirectional protection allows it to filter out current spikes from any direction. Its wide application field and working principle makes it one of the most popular types of TVS diodes on the market.
