TVS (Transient Voltage Suppression) diodes are used to protect sensitive electronics from damage due to high voltage transients. The 1SMC28AT3G is a commonly used TVS diode typically used in electronics applications. This article will cover the application fields and working principles of the 1SMC28AT3G.

The 1SMC28AT3G is a unidirectional diode, meaning it only allows current to flow in one direction. It has a common cathode connection and a common anode connection. The common anode connection is typically used to connect to the power source and the common cathode connection is connected to the device being protected.

The 1SMC28AT3G can be used in many different applications. It is commonly used in DC-DC converters, chargers, and power supplies to provide protection from transients. It is also used in automotive and industrial applications to provide protection from overvoltages. Additionally, it is often used in portable electronic devices such as mobile phones and tablets as a protection device.

The working principle of the 1SMC28AT3G is relatively simple. When the power supply voltage exceeds its specified limit, the diode begins to conduct. This conducting of current removes the excessive voltage through a safe routing, thus providing protection for the device being protected. This conduction of current also helps reduce the overall power consumption of the system, as the current that is removed is then not consumed by the device.

The 1SMC28AT3G is an effective device for providing protection from overvoltage transients and protecting electronic devices from damage. It is a versatile device and is suitable for use in a wide variety of applications. It is a reliable and cost-effective solution for protecting sensitive electronics, and has been widely used in the electronics industry for many years.
