V130LS20BP

The V130LS20BP is a 20mm radial leaded Varistor (also known as Variable Resistor) which is part of the GPP series of transient protection devices manufactured by General Semiconductor. This type of device is typically used to protect circuits from high voltage transients, such as those caused by electrostatic discharge (ESD) and lightning surges. The V130LS20BP is a bi-directional Varistor designed to be mounted on a printed circuit board.

Varistor devices in general are voltage-dependent, nonlinear resistors that divert high voltage transients away from the protected circuit components. The Varistor works by allowing current to flow in one direction at normal circuit voltages and diverting current to the output in the reverse direction when the voltage exceeds the Varistor’s breakdown (“clamping”) voltage. This prevents excessively high voltage from damaging the protected circuits.

The V130LS20BP Varistor has a working voltage of 130 volts and an operating range from 0 to 559 volts. The device also has a resistance of 18 ohms at 1 KHz and a tolerable power of 72 mW. The Varistor’s 1/2 wave let-through voltage rating is 1610 volts and its total energy-let-through rating is 19 joules. The maximum surge current is 20 amps.

The V130LS20BP Varistor provides a range of applications, such as automotive systems, audio equipment, lighting, and computer peripherals. It can also be used to protect electrical systems from transient voltage spikes. The device is also ideal for applications where high surge currents are present.

The Varistor’s working principle is based on the effect that a sudden application of a high voltage across a junction may cause a large current to flow through it. This is sometimes referred to as the “breakdown” or “avalanche” effect. In the case of the V130LS20BP Varistor, when a high voltage is applied to its terminals, the voltage will exceed the Varistor’s breakdown voltage and a large current will flow through it. This current will be diverted away from the protected circuit components and will dissipate safely to ground.

In conclusion, the V130LS20BP Varistor is an effective, low cost device for protecting circuits from transient voltage spikes. It has a wide range of applications and is ideal for protecting electrical systems in automotive, audio, and computer peripherals. The Varistor is designed to shunt away high voltages and divert them away from the protected circuit components. Its working principle is based on the breakdown effect it has when a voltage exceeding the Varistor’s rated breakdown voltage is applied across its terminals.
