Working Principle of B72210S0151K501

The B72210S0151K501 is a transient voltage suppressor (TVS) device, which means that it protects circuits from damage due to transient voltage and surge events. It works by providing a path for the current of the surge to flow, thus diverting it away from the circuit and protecting the circuit components from damage.

The varistor consists of a metal oxide ceramic element which acts as a non-linear resistor. When the voltage applied across this element exceeds its rated range, the resistance of the element quickly decreases allowing a high level of current to pass through it and be diverted away from the protected circuit.

Once the transient voltage has been diverted, the ceramic element begins to recover and its resistance slowly increases until it reaches its original level. The over-voltage protection is then restored and the circuit is safe from any further transient voltage events.

B72210S0151K501 is a high-energy surface-mount varistor which is suitable for use in a variety of applications. It provides a reliable form of over-voltage protection and is capable of handling up to 100A of peak pulse current. It is designed for 12-140V line-voltage systems and has a wide operating temperature range, making it suitable for use in a variety of environmental conditions.
