Varistors, MOVs, and other transient voltage suppression (TVS) devices are indispensable components in modern electronics, providing vital protection against voltage surges. With the emergence of compact higher-power electronics, the need for even more robust protection is rising. The 9401530000 application field and working principle are then discussed below.

Varistor

A varistor, also known as a voltage-dependent resistor (VDR), is a resistor whose resistance changes with the applied voltage. It contains two terminals, fabricated from zinc oxide material, which have a nonlinear current-voltage characteristic. The most common type of varistor is the metal-oxide varistor (MOV), with quickly varying resistance within a small voltage range. MOVs have a wide voltage limit range and can protect against extreme overvoltages. A typical example of the 9401530000 varistor is the 940K Series, which provides snapback voltage of 400V to 575V and a clamping voltage of 510V to 690V in 1000V DC. It has a maximum energy rating of 132 Joules and can handle up to 37A, making it a suitable component for protection against large transients.

Metal Oxide Varistor (MOV)

The metal oxide varistor (MOV) is the most commonly used type of varistor. It is composed of a metal-oxide semi-conductor material that acts as a resistance when a voltage is applied. The resistance of an MOV will increase as the voltage increases, allowing the MOV to act as a surge protector. The MOV can absorb most of the surge energy and divert the voltage to ground. The 9401530000 MOV has a capacitance range of 5-80 picofarads and can handle currents up to 35.7A, making it a great choice for surge protection. The MOV has snapback, stand-off, and clamping voltages of 580V, 160V, and 440V respectively.

Multi-layer Varistor (MLV)

Multi-layer varistors (MLVs) are a different type of varistor that offer additional protection against high transient voltages. MLVs are composed of multiple layers of varistor material, usually ceramic. MLVs are able to absorb surge energy more efficiently due to their higher capacitance. The 9401530000 MLV has a capacitance range of 30pF to 100pF and can handle currents up to 35A. It has snapback, stand-off, and clamping voltages of 680V, 150V, and 545V respectively.

Other TVS Devices

Transient voltage suppression (TVS) devices are used in many applications to protect against high transient voltages. There are many different types of TVS devices, such as zener diodes, diac breakers, and bladeless fuses. Zener diodes are a type of unidirectional, temperature-independent varistor that offers low resistance when a voltage is applied. Diac breakers are switches that open in response to an overvoltage, allowing current to be disconnected from the circuit. Lastly, bladeless fuses operate similarly to traditional fuses, except they are designed to interrupt power when a certain level of voltage is applied, thereby providing enhanced protection.

Conclusion

The 9401530000 application field and working principle are a great fit for any application requiring robust protection from transient voltage surges. Varistors, MOVs, and other TVS devices provide vital protection against voltage surges, enabling electronic components to be protected against damage from current and voltage spikes. By understanding the different types of TVS devices and their application fields, it is possible to make an informed decision when selecting the appropriate device for a given protection requirement.
