TVS - Diodes

A transient voltage surge suppressor (TVS) diode is a device used to protect electrical appliances and circuits from transient high voltage surges. These diode devices are also referred to as varistors or \'MOV\' (metal oxide varistor) and are designed to limit the amount of current that is passed through them when a high-voltage surge passes. TVS diodes come in many sizes and types, but all have the same basic functionality and are used for the same purpose.The SMA5J28CHE3/5A is a varistor, which is also known as a "metal oxide varistor", or MOV. It is a form of TVS diode specifically designed for use in pulse applications and designed to provide transient overvoltage protection. The device has two terminals and a resistive element that functions as a voltage limiter. It is used to protect circuits from voltage transients, which often occur in applications such as motor control, automotive, industrial, and consumer electronics.When there is a surge in the voltage, the varistor conducts the excess current AWAY from the protected circuit. This reduces the peak voltage, limiting it to a safe level. The varistor works by utilizing the internal resistance of its metal-oxide material, which controls the flow of current and provides protection from spikes in voltage.The maximum clamping voltage of the SMA5J28CHE3/5A is 28V, which is suitable for most standard power lines. It also features a low maximum leakage current (@25℃) of 5uA, meaning it will not affect the normal operating current of the protected equipment. Additionally, the device has a maximum surge current rating of 5A, providing sufficient protection against transient spikes in current.In summary, the SMA5J28CHE3/5A is a type of transient voltage surge suppressor diode, designed to protect electrical circuits from high-voltage transients. It utilizes the internal resistance of its metal-oxide material to reduce the peak voltage, limiting it to a safe level. The device has two terminals, a maximum clamping voltage of 28V, and a low maximum leakage current, enabling it to protect against a wide variety of transient voltage surges. With its 5A surge current rating, the SMA5J28CHE3/5A can provide comprehensive protection for most standard power lines.
