TVS (transient voltage suppressors) is a class of devices used to protect electronic systems from electrical transients. TVS devices are usually designed to be highly sensitive to sudden voltage changes, such as those from lightning strikes, ESD (electrostatic discharge), or other disturbances, and to absorb and dissipate the excess energy safely. Varistors, MOVs (metal-oxide varistors), and the V681HA32 are all examples of TVS devices.

V681HA32 is a type of Varistor, or metal-oxide varistor (MOV). A Varistor is a simple device consisting of two metal electrodes, a dielectric material, and a voltage-dependent resistor. When connected in a circuit, the Varistor acts as an ohmic resistance, meaning that its resistance is a function of the applied voltage. Typically, as the voltage increases, the resistance of the Varistor decreases. The V681HA32 is a general-purpose Varistor with a maximum working voltage of 32 VDC.

The primary purpose of the V681HA32 is to protect electrical and electronic systems from overvoltage conditions, such as those created by lightning strikes, electrical faults, or induced voltages. It is designed to clamp the voltage across the circuit component it is connected to, and dissipate the energy associated with the transient voltage safely. In addition to its protective function, the V681HA32 can also be used as a voltage divider or voltage regulator, making it a versatile device.

The working principle of the V681HA32 is based on the voltage-dependent properties of the Varistor. When the supply voltage exceeds the device’s breakdown voltage, the Varistor conducts electricity. This lowers the resistance of the Varistor, and the excess voltage is diverted safely away from the circuitry. The V681HA32 has a high initial breakdown voltage of 32 VDC, which ensures that it will activate in the event of a large transient voltage. The device also has a steep voltage-dependent resistance curve, meaning that it will quickly clamp the voltage to a much lower level, and dissipate the excess energy.

The V681HA32’s versatility and superior protective features make it an ideal choice for many applications. It is commonly used in automotive electronics, consumer electronics, and home appliances to provide overvoltage protection. It is also used in aerospace, military, and industrial electronics, where it is often connected between sensitive electronic components and a high-voltage source, such as an AC mains supply, to provide protection from electrical transients. In addition, the V681HA32 can also be used as a voltage divider or voltage regulator in low-voltage applications.

In conclusion, the V681HA32 Varistor is a versatile and reliable device, designed to protect electrical and electronic systems from electrical transients. It has a high initial breakdown voltage of 32 VDC, and a steep voltage-dependent resistance curve, enabling it to quickly clamp the voltage and dissipate the excess energy safely. The V681HA32 is suitable for a wide range of applications, from automotive and consumer electronics, to aerospace and military electronics.
