TVS (transient voltage suppressors) are devices such as varistors, MOVs (metal oxide varistors), and sidacs (silicon controlled rectifiers) used to protect circuits from surges and spikes. The B72520S200K1 is one such device. It is a fast-acting, surface-mount metal oxide varistor (MOV) with an operating voltage of 200V.

MOVs are used to protect against high voltage transients and surges. They have a Electro-Dynamic Resistance (EDR) that provides the characteristic of nonlinear resistance between their terminals. When an AC waveform exceeds the EDR clamping voltage, the MOV limits the waveform and diverts current to ground. This protects the underlying circuit from damage.

The B72520S200K1 is designed for use in automotive applications and general consumer electronics such as LCD TVs, personal computers, and electric power supplies. Its small size and high clamping voltage make it ideal for applications that require a surface-mount component. It features high reliability and surge current ratings, plus a breakdown voltage of 200 volts and a clamping voltage of 441 volts.

In terms of its working principle, the B72520S200K1 is an electro-dynamic device. Upon the application of an AC waveform with a peak voltage greater than the EDR clamping voltage, the device begins to conduct, diverting the current to ground and limiting the waveform to a safe level. It offers a non-linear resistance, so as the voltage increases, the current passing through the MOV decreases.

The B72520S200K1 is broadly used in automotive applications and personal electronic devices, due to its low-cost and high-reliability. It is particularly useful in applications where size and weight are limited, such as cell phones or portable CD players. In these applications, it can provide surge protection for sensitive electronics without taking up too much space or adding too much weight.

In short, the B72520S200K1 is an MOV designed for automotive applications and consumer electronics. It has a high clamping voltage, high surge current rating, and a breakdown voltage of 200 volts. Upon the application of an AC waveform in excess of the EDR clamping voltage, it diverts current to ground, limiting the waveform and protecting the underlying circuitry from damage.
