V30MLA1210LNH

TVS - Varistors, MOVs

The V30MLA1210LNH is a TVS (Transient Voltage Suppressor) which can be used in a variety of applications. It is a ceramic multilayer varistor with a sensitive response to transient voltage changes. This varistor is a dual element varistor, which means it has two components that work together to protect circuits against transient overvoltages. The two components are the positive joule (PJ) element and the negative joule (NJ) element. This type of varistor offers superior protection against overvoltages and can handle higher peak current levels than other varistors.

The V30MLA1210LNH has a wide operating voltage range of 12V - 18V and a working temperature range of -30C to 85C. The surge current capacity is also impressive with a maximum rating of 10kA (10 thousand amps). As for insulation voltage, the V30MLA1210LNH can withstand up to 1000V and is UL approved.

Application Field

The V30MLA1210LNH can be used in a variety of applications, such as in automotive, telecommunications, solar, and industrial applications. In automotive applications, it is used for surge protection in various electronics, such as engine control units (ECUs), airbag systems, and powertrain control modules. It is also used for overvoltage protection in telecommunications, solar, and industrial applications. It can be used to protect against transient overvoltages across a wide range of frequencies.

Working Principle

The working principle of the V30MLA1210LNH relies on the two components mentioned earlier, the positive joule (PJ) and negative joule (NJ) elements. When an overvoltage occurs, the PJ element will trigger first, preventing the voltage from rising further. This is done by diverting the energy of the transient overvoltage to the NJ element. The NJ element, meanwhile, is designed to handle the energy of the transient and dissipate it to ground, thus protecting the circuit.

The V30MLA1210LNH is also equipped with a built-in clamping mechanism, which helps to limit the overvoltage to within safe levels. This is done by clamping the overvoltage directly to the rated voltage of the varistor. The V30MLA1210LNH can also handle higher peak current levels than other varistors, making it an ideal choice for a variety of applications.

Conclusion

The V30MLA1210LNH is an ideal choice for overvoltage protection in a variety of automotive, telecommunications, solar, and industrial applications. It offers superior protection against transient overvoltages with its dual elements and built-in clamping mechanism. It is also able to handle higher peak current levels than other varistors. With its wide operating voltage and temperature ranges, it is well-suited for a variety of applications.
