TVS - Varistors, MOVs, are the basic components of circuits used in a variety of protective circuits. The V175LU10AP is a voltage-dependent resistor designed to prevent, divert and limit overload voltage transients in a circuit. The V175LU10AP is a very versatile component and can be used in a wide range of applications.

The V175LU10AP is an epoxy-encapsulated, non-polar device with triple protection features. It consists of two elements which respond either independently or jointly to applied voltage transients. When exposed to a surge that is greater than the rated clamping voltage, the varistor will rapidly reduce the voltage to a safe level by diverting the current away from the protected circuit. The MOV will then disconnect the protected circuit from the outside world, allowing any energy to dissipate.

Application Field

The V175LU10AP is suitable for use in a wide range of application fields, including:

• Communication and network protection
• Industrial equipment protection
• High-voltage power equipment protection
• Automobile equipment protection
• Lighting protection

In addition, the V175LU10AP can be used in applications where a high VDE 0884 Revision 01 conformance is required.

Working Principle

The V175LU10AP is designed to divert, absorb and limit current and voltage surges. The primary elements are two redundant semiconductor layers, formed by high-capacity, non-polar zinc oxide varistor material. This ensures a robust surge protection capability, even after multiple transient events.

The V175LU10AP is essentially a voltage-dependent resistor with a moveable contact, which responds rapidly to voltage transients. The MOV compares the voltage waveform to a set reference level – if it exceeds the reference level, it rapidly switches on and reduces the voltage to a safe level.

The two layers also have two seconday elements – a varistor to reduce the voltage, and a thermistor to limit the current. These two elements work together to protect the circuit from further damage. The MOV will then disconnect the protected circuit from the outside world, allowing any energy to dissipate.

The V175LU10AP is also an epoxy-encapsulated device, which is rated up to 1250V. This provides superior protection against dielectric breakdown and physical shock, as well as providing superior moisture resistance. It is also UL 94V-0 rated, making it suitable for a wide range of industrial applications.

Conclusion

The V175LU10AP is a very versatile component suited for a wide range of applications. It is designed to protect circuits from overvoltage and can respond rapidly to voltage transients. It is also epoxy-encapsulated and is rated to 1250V, providing superior protection against dielectric breakdown and physical shock.
