TVS (transient voltage suppressor) and MOV (metal oxide varistor) devices are important components of a wide range of electronic and electrical equipment. They protect the electronics and other equipment from transient voltage events, also known as ESD, EFT, or surge protection. The V68CH8T is an advanced TVS / MOV hybrid device that offers superior protection in a wide range of applications. This article will discuss the application fields and working principles of the V68CH8T.

Application Field of V68CH8T

The V68CH8T is primarily used in types RTN (Return to Neutral) and Burst Mode protection circuits. It is suitable for protecting communication, AC/DC power transmission, and automotive components from transient events such as ESD, EFT, surge and coming wave. It can also be used in applications such as in-vehicle antennas, GPS modules, LCD TV, portable terminal devices, and various other consumer electronics.

Working Principle of V68CH8T

The V68CH8T is a hybrid TVS / MOV device, which combines the properties of both TVS and MOV components and provides superior surge suppression characteristics. During a surge event, the TVS portion of the device acts as a triggered varistor and protects the circuit from high voltage engagements. The MOV portion of the device further reduces voltages by providing additional clamping capability. The V68CH8T also offers very fast response time, enabling it to protect against extremely fast surge events.

The V68CH8T also offers a wide range of protection and voltage clamping parameters, enabling it to be used in a variety of applications. It can be used for both absolute peak and transient voltage protection, and offers two different thresholds of voltage clamping, a Large Signal Response (LSR) and a Small Signal Response (SSR). The SSR threshold is enabled by adding a composite resistor between the MOV shell and the common pin of the device. It can also be used for both over-voltage and over-current protection.

Conclusion

The V68CH8T is an advanced TVS / MOV hybrid device that provides superior protection in a wide range of applications. It is mainly used for Return to Neutral (RTN) and Burst Mode protection circuits, and is suitable for protecting communication, AC/DC power transmission, and automotive components from transient events such as ESD, EFT, and surge. The V68CH8T also has a fast response time and offers a wide range of protection parameters, enabling it to be used in a variety of applications. This makes it ideal for use in consumer electronic devices and other applications.
