随着现代车辆电子化程度不断提升，DCU（Domain Control Unit，域控制器）成为车辆电控系统的核心之一。DCU负责整合多个功能模块，其稳定性与安全性至关重要。为确保DCU稳定运行，保护元器件与功率元器件的应用扮演着关键角色。  保护元器件（如TVS二极管、ESD保护器件）可有效抵御突发电压尖峰、静电放电（ESD）等异常情况。常见规格如TVS二极管的击穿电压范围可达12V至200V，提供车用电子电路所需的瞬态电压保护。

另一方面，功率元器件确保DCU电源转换过程中的高效率与低发热。TSC提供额定电压为40V至100V车用MOSFET ，还有Schottky，适合12V与48V车用系统。结合TSC保护元器件与功率元器件的设计，不仅提升了DCU的耐用度与稳定性，还优化了能源效率，为车辆电子系统提供更安全、更可靠的运行环境。

As modern vehicles become increasingly electronic, the DCU (Domain Control Unit) has emerged as one of the core components of a vehicle’s electronic control system. The DCU is responsible for integrating multiple functional modules, making its stability and safety crucial. To ensure stable DCU operation, protective components and power components play a key role. Protective components, such as TVS diodes and ESD protection devices, effectively guard against sudden voltage spikes, electrostatic discharge (ESD), and other abnormal conditions. Common specifications for TVS diodes include a breakdown voltage range from 12V to 200V, providing the necessary transient voltage protection for automotive electronic circuits.

On the other hand, power components are designed with high voltage tolerance and low on-resistance (RDS(on)) to ensure high efficiency and low heat generation during DCU power conversion. Automotive MOSFETs are typically rated between 40V and 100V, making them suitable for 12V and 48V vehicle systems.By combining TSC’s protective and power components in the design, the durability and stability of the DCU are enhanced, while energy efficiency is optimized, ensuring a safer and more reliable operating environment for automotive electronic systems.
