Byd entered the automotive industry in 2003 and started the research and development of electric vehicles, and by 2024 became the first brand in the world to reach the 9 millionth energy vehicle off the production line. The Dynasty series and the Ocean series developed by the company are two popular product lines in the new energy vehicle market, each with distinct characteristics. The design inspiration of the Dynasty series comes from traditional Chinese culture, while the design inspiration of the ocean series comes from Marine elements, emphasizing fashion, youth and a sense of science and technology.

As a leader in new energy vehicles, BYD has been committed to technological innovation and product upgrades, and has extremely high requirements for the quality and performance of automotive electronic components. Yixing Electronics, as a semiconductor solution provider, is very honored to be recognized by BYD brand!

EXPSEMI products are used in many lighting parts, including: headlights, rear lights, interior atmosphere lights and other important parts. The vehicle lighting system provides road lighting, signal indication, auxiliary driving and aesthetic and personalized functions to improve the aesthetic and comfort of the vehicle on the basis of ensuring driving safety.

As can be seen from the application block diagram of the vehicle lighting system, TVS (that is, transient suppression diode) plays an important role in it. TVS is an efficient circuit protection device, when the circuit receives an instant of high energy impact, TVS instantaneously converts from the normal state to the overvoltage state at a very fast speed, absorbs the instant large current, and protects the circuit components behind it from damage.

The vehicle electrical system may produce power supply voltage fluctuations and surges under starting, stopping or other working conditions. At this time, TVS can effectively prevent the lamp from being damaged due to overpressure.
