Transient Voltage Suppressors (TVS) are components that are designed to protect electrical and electronic components from potentially damaging voltage spikes, transients, and overvoltage conditions. The TVS includes devices such as varistors, MOVs, and other over-voltage protection devices. SMOV34S151NP is a MOV with built-in protection against high reversed bias voltage and surge current. It works with an extremely low capacitance and can be used for voltage modulation, protection, and stabilization applications.

The SMOV34S151NP is a 3-terminal non-polarized tungsten oxide-based over voltage protection device. It provides protection against high voltage transients and overvoltages such as those caused by electrostatic discharges (ESD), lightning strikes, and other power faults. It may also be used to suppress ringing on PCBs, such as those used in video display units.

The SMOV34S151NP mainly works by blocking excessive voltage exceeding the nominal voltage rating of the device. When a transient voltage spike occurs, the Zero Power Standoff Voltage (ZPS) of the device is exceeded and the SMOV then presents a low impedance path. In this mode, it reduces the peak voltage on the protected circuit to an acceptable level.

The SMOV34S151NP is an ideal application for use in consumer electronics and telecom equipment, such as smartphones, tablets, laptops, and other portable devices. The device is also suitable for use in industrial electronics, automotive systems, and medical instruments. Its robust design ensures reliable performance and its protective feature guards delicate components from electrical breakdowns and damage due to atmospheric conditions.

For its working principle, the SMOV34S151NP features a positive temperature coefficient, where its actual voltage breakdown is proportional to its temperature. The device operates by conducting current through its junction in the event of an overvoltage. During an overvoltage, the junction conducts current and the voltage will be diverted from the protected circuit. The SMOV dissipates the overvoltage energy in the form of heat and limits the voltage during normal operation.

The SMOV34S151NP is a fast and reliable overvoltage protection device that can be used in a variety of applications. It features an advanced design combined with a low capacitance construction to effectively protect sensitive components and circuits while dissipating the excess energy as heat.

In summary, the SMOV34S151NP is a reliable and efficient overvoltage protection device. It is designed to protect critical electrical and electronic components from potentially damaging voltage spikes, transients, and overvoltage conditions. The device is suitable for use in a wide variety of consumer electronics, telecom equipment, and other applications. Its fast response time and low capacitance construction make it an ideal device for use in sensitive applications.
