TVS - Varistors, MOVs

TVSs or Transient Voltage Suppressors, also known as Varistors, MOVs, or Supressile Diodes, are devices primarily designed to regulate or limit voltage and current levels in areas where the power supply or the environment may be particularly volatile. They are essential for maintaining stable AC and DC power supply to the circuit, allowing it to continue operating without disruption. Depending on the type of circuit, the TVS can also act as a surge protector, preventing damaging levels of overvoltage from reaching the system.TheB72220T2511K105is an example of a TVS device intended for general use in high-throughput, high-frequency circuits. The B72220T2511K105 is sold as a bilateral Zener diode with a reverse standoff voltage of 25V and a maximum bipolar peak pulse current of 11000A. This device is able to provide an average clamping voltage of about 36V, surpassing the 27V rating of the Zener diode. This device is also able to handle a peak surge current of up to 20kA, capable of protecting the circuit from transients up to a rating of 13V.The B72220T2511K105 is designed for operation in the environment ranging from -55°C up to 125°C without compromising its performance. Additionally, the device is compliant with requirements of the AEC-Q200, AEC-Q101, E1, ECE, and H-level qualification. These qualifications enable the device to be compliant with industry standards aimed for use in automotive and power management applications.Due to the reduced reverse recovery time of modern circuits, devices with fast response rates have become increasingly important in automotive and power management applications. The B72220T2511K105, with its fast response time of 39ns, is capable of providing large transient protection in these high frequency applications while still being low capacitance and low profile. This low profile package allows for easier implementation of surface-mounted technology products.The B72220T2511K105 works by detecting excessive voltage levels in an electrical circuit and then using its internal resistance and capacitance to limit or suppress any current that surpasses the preset threshold. This serves to reduce any voltage build-up, thus preventing any electrical surge from damaging the circuit components. This is possible due to the device’s unique ability to absorb and dissipate energy, redirecting it away from the main board. The circuit’s internal impedance also helps dissipate any excess heat generated by the absorption of this energy.The B72220T2511K105 is capable of providing superior performance in a wide range of applications, such as power management, motor control, and home appliances. It is also suitable for use in electric vehicle systems due to its high-efficiency, low noise, and broad operating temperature range. With its compliance to many industry standards, the B72220T2511K105 can help provide a high level of protection in applications that require both large transients and low impedance.
