YAGEO Launched Circuit Protection Component- Transient Voltage Suppressor (TVS) for rapid-growing Automotive and 5G communication markets

2021/08/04

Worldwide innovative passive manufacturer-YAGEO Corporation, in response to the fast-growing electric vehicle and 5G communications market demand, had launched the circuit protection component product, TVS which is processed with semiconductor procedure.

The TVS circuit protection components are designed in single PN junctions or multi-integrated PN junctions fabricated by the semiconductor diffusion process. TVS series components have high reliability, low impedance, low clamping voltage, and fast response speed compared to other circuit protection components. Furthermore, TVS is precise at breakdown voltage. Usually, the breakdown voltage of TVS has a tolerance of ±5%. Based on the advantages above, TVS can be used at applications with higher requirements, such as automotive, industrial control, lighting, communication, and applications like DC power lines, RS485 interfaces, communication interfaces, I/O port.



For the high requirements of automotive applications, TVS becomes essential because of its fast response speed, high reliability, low clamping voltage, and small outline package. For vehicles' safety and service life, it is necessary to respond quickly when the load dump occurs. An example here is the DC power input port of automotive electronics that uses a 24V system. It generates a large interference pulse during the load dump caused by the complicated and variable driving environment that leads to damage to the back-end DC/DC and integrated circuits of automotive electronics. TVS can suppress interference immediately with its picosecond response speed and precise breakdown voltage.

 

As a low-speed communication port representative, RS485 has a long communication transmission distance, and its transmission lines are usually exposed outdoors, so it is easy to introduce transient over voltage interference due to lightning strikes and other reasons. The RS485 transceiver usually works in a low-voltage state (about 5V). Its anti-interference is weak. There is no path to divert the transient voltage interference. The communication interface chips are easy to be damaged without proper protection. As an over-voltage protection device, TVS is the preferred component for the RS485 surge protection because of its advantages, such as fast response and low clamping voltage.

 

In response to the fast-growing electric vehicle and 5G communications market demand increasing demands of Circuit Protection Component, YAGEO recommends TVS for the characteristics of fast response speed, high reliability, low clamping voltage, and small outline package. The overvoltage protection component plays an important part and will continue to be used in more product applications.
