V150LS20C is an overvoltage protector component used in areas such as consumer electronics and automotive electronics. It is a transient voltage suppressor (TVS) and is based on varistors, metal oxide varistors (MOVs). These components have been in the market for more than a decade but have only recently become popular thanks to their superior performance.

The main purpose of a V150LS20C is to protect electronic circuits from voltage spikes. It is normally added at the input stage of the circuit to provide overvoltage protection. Generally, V150LS20C is a bi-directional, silicon avalanche diode. A varistor or a MOV is nothing but a silicon diode with a secure reverse breakdown voltage.

The V150LS20C works by limiting the voltage applied to the protected circuit. It does this by absorbing the energy of the voltage spike and dissipating it as heat. When the external voltage exceeds the specified clamping voltage, the varistor will conduct current, trying to equalize the voltage on either side of it. It is at this point that the varistor needs to dissipate the energy of the voltage spike to maintain the current flowing through the protected circuit. The protection is provided in both directions, i.e. for both positive and negative voltages.

The V150LS20C is typically used for data lines, A/V lines, and power lines. It can also be used as a protection against transients in applications such as uninterruptible power supplies, motor drives, and power distribution systems. The protection is provided between the on-board circuit and the external environment, thus providing a good degree of safety against surge events.

The V150LS20C comprises two main components: the varistor and the bypass diode. The varistor, which is a semiconductor device, acts as a voltage-dependent resistor and provides the desired protection. The bypass diode is used to divert the current away from the protected circuit when the varistor triggers. This helps to reduce the stress on the circuit components, thus providing a greater degree of protection.

In conclusion, the V150LS20C is a powerful overvoltage protector and is suitable for a variety of applications. Its protective characteristics make it a popular choice for consumer electronics and automotive electronics applications where high levels of overvoltage protection are required. The V150LS20C is also widely used in on-board protection circuits, uninterruptible power supplies, motor drives, and power distribution systems.
