TVS - Varistors, MOVs

V625LS40AP is a series of varistor products which offer better performance and improved reliability over conventional varistors. It is widely used in power, electric and electronic applications to protect circuits from transients, overvoltage events, and similar threats.

The V625LS40AP varistors offer rated working voltages from 150V to 1500V, clamping voltage range of 8V to 1500V, a temperature coefficient of ± 60ppm/K, and a very low temperature coefficient of just 0.001mV/K. The series have excellent surge capability and are able to withstand very large surge voltages. The robust design of the series ensures that it can easily handle high pulse discharge currents.

V625LS40AP works by clamping the voltage pulses to a pre-set level. This prevents the surge from damaging the circuit components. The varistor also dissipates the surge pulses as heat, making them harmless. The devices have a very fast response time to ensure that high-speed transient surges and overvoltage conditions are detected and clamped quickly.

These devices can be used in various power and electronic devices such as TVs, computers, telecommunications equipment, industrial automation systems, power supplies, motor control systems, etc. For example, it can be used in TVs to reduce the risk of TV damage from electrostatic discharges (ESD) or lightning. It can also be used in computer systems to protect components from spikes or surges.

To ensure that the protection is reliable, the varistor must be carefully selected according to the application. The various parameters of the varistor such as rated working voltage, clamping voltage, temperature coefficient, maximum rated power dissipation, surge current rating, and operating life must be taken into consideration before selecting the appropriate device. In addition, the selection is also based on the frequency of the surges and the surge strength.

In summary, the V625LS40AP series of varistors provide reliable protection against transient surges and overvoltage conditions, making it an ideal choice for various power and electronic devices. With its robust design, fast response time, and excellent surge capacity, it is the best possible solution for most applications.
