Introduction

0070.6081.T2 is a transient voltage suppressor (TVS) device that combines the energy absorption capacity of a varistor with the high surge protection rating of a transient voltage suppressor. Varistors are voltage-dependent, non-linear electrical devices used to protect sensitive circuits from transient overvoltages. They do this by temporarily clamping excessive voltage and releasing it in a controlled manner. Unlike other surge protection devices such as MOVs (metal oxide varistors), 0070.6081.T2 devices can withstand more powerful surges without causing damage to sensitive circuits.

Application Fields and Working Principle

0070.6081.T2 devices are used in a number of applications where circuit protection is needed. In the automotive industry, they are used to protect passenger car and truck electrical systems from voltage transients caused by lightning, power outages, and other similar events. In the industrial realm, 0070.6081.T2 devices are used to protect industrial equipment from voltage surges and spikes caused by power fluctuation or startup or shut down of electrical systems.The basic working principle of 0070.6081.T2 devices is to absorb electrical surges and spikes and channel their energy. The device utilizes a zener diode connected in series with a varistor. The zener diode rapidly conducts current when the voltage reaches its maximum breakdown voltage. The varistor does not conduct current until the voltage reaches the limit of its breakdown voltage. The function of the zener diode is to reduce the voltage to a safe level when a surge occurs. When the voltage reaches a certain level, the zener diode will become forward biased and begin to conduct electricity, effectively lowering the voltage of the surge. The varistor, on the other hand, absorbs the energy from the surge and gradually releases it in a controlled manner. This is beneficial because it prevents circuit damage caused by energy spikes.

Conclusion

In conclusion, the 0070.6081.T2 is a transient voltage suppressor device made up of a zener diode and a varistor used to protect sensitive circuits from transient overvoltages. Its application fields include the automotive and industrial industries, where it is used to protect electrical systems from voltage transients and surges. The device works by using the zener diode to reduce the voltage of the surge and the varistor to absorb and slowly release the energy.
