With the rapid growth of automotive industry, the development of automotive electronics is an inevitable trend. In the process of designing cars, electric vehicles, motor drives, car lights and car entertainment information systems are protected from surge, voltage transients and ESD damage. The TVS tube is a device to protect transient overvoltages, which is an ideal scheme to protect automotive electronic products.
Electric motor drive of electric vehicle
Because of the large working voltage range of electric vehicles and hybrid electric locomotives, it is a necessary problem to prevent overvoltage failure of IGBT in the condition of braking energy recovery, generator power generation and short circuit protection. Active voltage box function has been widely used as an effective way to prevent IGBT overvoltage failure. As an important part of the circuit, TVS diode acts as an active box. It can suppress impulse voltage and protect IGBT.
Automobile lamp
Automotive lighting system is one of the essential systems for vehicle safety driving. It mainly includes external lighting, interior lighting, external signal lamps, interior signal lamps and lanterns. The TVS diode can protect the driver and the LED lamp from the surge from the power line, and the TVS diode array can protect the ESD from the CAN/LIN bus, whether it is a car light or an internal ambient light.
Automotive entertainment information system
With the rapid development of cars, cars are already or are going to be supercomputers loaded on wheels, so the super computer needs to be protected in accordance with the level of the car. One of the most important applications is the automotive entertainment system. The automobile entertainment system has a large number of high-speed interfaces and antennas. The TVS diode, TVS diode array, high molecular polymer ESD suppressor, EMI filter, MLV varistor, PPTC and other products can play the role of overvoltage and overcurrent protection.
In the field of automotive electronics, TVS tube has been widely applied. The above is the application of automotive electronic TVS tube.
