Yageo Launches TVS Transient Suppression Diode Protection Components for Automotive and 5G Communication Applications

     The world leader in passive components - Yageo Group, in response to the fast-growing electric vehicle and 5G communication market demand, mainly promotes transient suppression diode (TVS) protection components made of semiconductor diffusion process. TVS is a single PN junction or multiple PN junction integrated components made by semiconductor diffusion process.

     TVS has high reliability, low dynamic internal resistance and low clamping voltage. Compared with other overvoltage protection components, TVS has a faster response speed. TVS has the characteristics of high breakdown voltage accuracy, and the breakdown voltage is generally ±5% deviation. Based on the above advantages, it is suitable for occasions with high requirements for protection devices, such as: automotive electronics, industrial control, lighting and communication industries; DC power lines, RS485 interface, communication power supply and I/O interface applications, etc.

     For applications with high protection requirements in automotive electronics, TVS with fast response speed, high reliability, low clamping voltage and small package has become a key protection device. For example, the DC power input port of 24V system automotive electronic products, due to the complex use environment and the variability of driving environmental factors, will generate large interference pulses when load dump occurs, which will cause damage to the DC/DC and integrated circuits of the automotive electronic products. Damage, for driving safety and service life, requires a quick response when load dump occurs. TVS can suppress interference in the first place with picosecond response speed and accurate breakdown voltage.

     In terms of communication applications, taking the commonly used communication interface - RS485 as an example, due to the long communication transmission distance and its transmission lines are usually exposed to the outdoors, it is easy to introduce transient overvoltage interference due to lightning strikes and other reasons, and RS485 transceivers usually work at low voltages. state (about 5V), its own anti-interference is low, there is no path that can divert the transient voltage to interfere in the first time, if not properly protected, it is easy to cause damage to the communication interface chip, and TVS has the advantages of low clamping voltage and other advantages It can be used as the preferred device for surge protection of RS485 communication interface.

     In order to meet the demand for protection components caused by the increasing demand for electric vehicles and 5G base stations year by year, Yageo’s main TVS protection components are featured with fast response, high reliability, low clamping voltage and small package. It occupies an indispensable position in the components, and we expect to shine in the future application market.
