TMOV34S661MP is a kind of transient voltage suppressor (TVS) devices, which is also known as a Transient Voltage Suppressor (MOV) or Varistor. It is a useful device to protect various electronic equipment from overvoltage as it is able to quickly clamp a voltage spike to a lower level. In this article, we will discuss the application field and working principle of TMOV34S661MP.

Application Field of TMOV34S661MP

TMOV34S661MP has two main applications: zero clamping voltage protection and ESD protection.

For protective circuit applications, TMOV34S661MP is primarily used for zero clamping voltage protection if the voltage is higher than its breakdown voltage. It can also provide ESD protection if the voltage is lower than its breakdown voltage. Additionally, TMOV34S661MP can be used for protection from overvoltage transients or ESD, as well as line-to-line protection from surge currents.

TMOV34S661MP is also suitable for consumer electronic products such as industrial control systems, telecommunication and LAN protection against EFT/B lightning and surge and ESD applications. Moreover, TMOV34S661MP can be used for EFT/B and surge protection in automotive, industrial, and other sensitive electronic equipment to prevent breakdown caused by voltage spike.

Working Principle of TMOV34S661MP

TMOV34S661MP adopts the principle of metal oxide varistor (MOV) and when voltage is applied to it, it begins to conduct current. The basic working principle is that when the external circuit voltage exceeds its breakdown voltage, the device will break down and the voltage will be clamped at the breakdown voltage. The clamping voltage is dependent on the breakdown voltage, which is related to the MOV material.

When the external circuit voltage is lower than its clamping voltage, the device will be in a non-conductive state and the current will not flow through it. Thus, TMOV34S661MP clamps the voltage to protect sensitive electronic equipment from potential damages, lengthens the service life of the electronic devices and protects the circuits from being damaged caused by overvoltage transients or ESD.

Conclusion

In conclusion, TMOV34S661MP is a kind of transient voltage suppressor (MOV) device, which can protect various electronic equipment from overvoltage and ESD. It is widely applied in consumer electronic products and other sensitive electronic equipment to protect the circuits from breakdown caused by voltage spike. Its working principle is that when the external circuit voltage exceeds its breakdown voltage, the device will break down and the voltage will be clamped at the breakdown voltage.
