SMOV25S321NP Application Field and Working Principle

TVS (Transient Voltage Suppressors) - Varistors, MOVs are components designed to protect the other components of the circuit against electrical transients, such as electrical surges, voltage spikes, and electromagnetic interference (EMI). Transient Voltage Suppressor (TVS) devices are semiconductor components that react to transient (short-term) overvoltage conditions by conducting current away from critical components. SMOV25S321NP Transient Voltage Suppressor (TVS) devices are designed to provide protection from overvoltage transients in electronic components.

Application Field

SMOV25S321NP Transient Voltage Suppressors (TVS) are designed for use in applications in which they will provide transient protection from overvoltages, such as in industrial computer systems, aviation and military equipment, and other high-speed digital and logic circuits. SMOV25S321NP Transient Voltage Suppressors (TVS) are also suitable for use in automotive applications, as they are designed to withstand high-speed pulses, high temperatures, short circuits, and high-energy transients.

Working Principle

The SMOV25S321NP Transient Voltage Suppressor (TVS) device works on the principle of avalanche breakdown in a diode. When the voltage across the device exceeds a certain voltage threshold, known as the breakdown voltage, the diode\'s structure or attributes enable it to conduct current. This is known as avalanche breakdown, as current is passed through the device in a controlled avalanche-like fashion. The amount of current conducted determines the amount of voltage across the device, thus providing transient suppression.

When the transient voltage is present at the electrical component, the SMOV25S321NP Transient Voltage Suppressor (TVS) takes over the job of absorbing the excessive energy. It acts as a buffer between the component and the transient event, and dissipates the excessive energy to ground. Depending on the amount of energy being stored in the transient, the SMOV25S321NP Transient Voltage Suppressor (TVS) device will react by either conducting the excess current or by limiting the voltage. The SMOV25S321NP Transient Voltage Suppressor (TVS) device will then return the system to normal operation as the transient dissipates.

The SMOV25S321NP Transient Voltage Suppressor (TVS) is a fast-response transient voltage inhibitor designed to protect sensitive components from over-voltage transients. It features an insulated-gate bipolar transistor (IGBT) protection device that is triggered when the voltage exceeds a predetermined level. It is commonly used in applications that require low-voltage and/or high-power transient protection solutions, such as AC mains and automotive power supplies. The SMOV25S321NP Transient Voltage Suppressor (TVS) is capable of providing overvoltage protection from both electrostatic discharge (ESD) and surge pulses.

In summary, the SMOV25S321NP Transient Voltage Suppressor is a fast response transient voltage inhibition device designed to protect sensitive components from over-voltage transients. It is suitable for many applications, including industrial computer systems, aviation and military equipment, and automotive power supplies. This device is capable of providing overvoltage protection from both electrostatic discharge (ESD) and surge pulses.
