TVS or transorbs are needed to protect sensitive electronic components in various electronic systems. This is because their high discharge capacities provide quick clamping and short, sharp, overvoltage pulses. Varistors, which are a kind of protection device, protect against lightning or other electrostatic discharge (ESD) by limiting the voltage applied across the system. MOVs, or metal oxide varistors, are particularly useful because they have a high capacity for energy and can effectively dissipate surges.

The SMOV25S151MP is a metal oxide varistor specifically designed for ESD and overvoltage protection applications. It has a high capacitance rating, which means it can clamp rapid voltage rises quickly, limiting any current that may be caused by an overvoltage event. The SMOV25S151MP is suitable for a variety of applications, including data networks, automotive, consumer electronics, and medical equipment. Its robust construction and wide temperature range makes it ideal for most applications.

The SMOV25S151MP is made up of several components, each with their own properties and functions. The core element of the device is the ‘varistor’, which is a semiconductor that is designed to melt down and clamp a preset voltage. The insulation layer is made of a varistor with a thin layer of insulation on top of it. This insulation helps reduce any arc-over voltages that may occur during an over-voltage event. The two electrodes are made of metal oxide and are insulated from each other. These two electrodes are arranged in such a way that, when an over-voltage event occurs, an arc-over voltage occurs between them, resulting in the varistor melting down and clamping the voltage.

The SMOV25S151MP is also equipped with a bypass capacitance. This caps off any high frequency pulses that may occur during an over-voltage event, allowing the SMOV25S151MP to limit the peak voltage to its rated value. This increases protection for underlying circuits. Additionally, the SMOV25S151MP is fitted with a temperature coefficient that will trigger the device’s clamping voltage to rise if the temperature increases. This helps to ensure the device is not destroyed by prolonged high temperatures.

The SMOV25S151MP is a very versatile device that offers high levels of protection against over-voltage events. Its wide range of applications makes it suitable for both commercial and industrial applications. Its high capacitance rating and temperature coefficient helps to ensure it provides reliable protection against over-voltage events.
