The automotive electronics sector has experienced rapid growth, driven by the increasing integration of electronic components in vehicles. TVS diodes are essential in protecting automotive electronics from voltage transients caused by inductive loads, such as motors and solenoids, and by external sources like lightning strikes or electrostatic discharges. In modern vehicles, the application of advanced driver-assistance systems (ADAS), infotainment systems, and electric powertrains has heightened the demand for effective voltage protection solutions. The protection of critical systems, including sensors, cameras, communication modules, and electronic control units (ECUs), is paramount in maintaining vehicle safety and performance.
The rise of electric vehicles (EVs) and hybrid vehicles further amplifies the need for transient voltage protection. As these vehicles become more complex, incorporating battery management systems, charging systems, and high-voltage components, TVS diodes are increasingly being used to protect both the internal electronics and the connection interfaces between the vehicle and charging stations. This growing trend of automotive electrification and the need for improved safety and reliability are expected to fuel the demand for TVS diodes in the automotive sector in the coming years.
Power supplies are integral to almost every electronic system, from industrial machines to consumer devices. The presence of transient voltage spikes can severely affect the performance and longevity of power supply units (PSUs), which are critical for converting electrical power to usable form. TVS diodes are used extensively in power supply applications to prevent equipment damage caused by voltage surges that may arise from sources like lightning strikes, grid fluctuations, or switching transients. These diodes act as a first line of defense, clamping excessive voltage and ensuring that sensitive components within the power supply remain functional and protected from high-voltage events.
The growing emphasis on renewable energy systems, such as solar power generation and wind energy, also drives the need for robust power supply protection. As these systems become more integrated into the electrical grid, they must be protected from power quality issues, including transients. The increasing use of uninterrupted power supplies (UPS) in industrial, data center, and critical infrastructure applications further expands the TVS diode market within the power supply segment. As industries demand greater power reliability and more advanced power electronics, the role of TVS diodes in this market will become increasingly vital.
The industrial sector encompasses a wide range of applications, including automation, robotics, control systems, and manufacturing processes.
