TVS tube (transient voltage suppressor) is widely used in life, almost involving all aspects of modern electronic equipment and systems. The following is a detailed summary of the application of TVS tubes in life:

First, household appliances

TVS tubes play an important role in household appliances, mainly used to protect circuits from overvoltage shocks. For example:

• Televisions, refrigerators, washing machines and other electrical appliances, TVS tubes can protect the sensitive components on the circuit board, such as microprocessors, microcontrollers, etc., to avoid damage caused by electrostatic discharge, power surge, etc.

• In high-power appliances such as air conditioners and water heaters, TVS tubes can also effectively inhibit the transient voltage generated when the motor is started and closed, and protect the electronic components inside the appliances.

2. Communication equipment and computer systems

• Mobile phones, computers, routers and other communication equipment and computer systems have a large number of integrated electronic components, which are very sensitive to overvoltage and transient voltage. TVS tubes protect these components from electrostatic discharge, transient voltages caused by interface insertion and removal, and overvoltage shocks caused by natural factors such as lightning.

• In communication ports such as RS232, 485 and CAN, TVS tubes can also provide effective protection to ensure the stability and reliability of data transmission.

Third, the field of automotive electronics

With the continuous development of automobile electronics, TVS tubes are more and more widely used in the field of automotive electronics. For example:

• In automotive electronic components such as onboard power supplies, ECU control boards and DVD navigation devices, TVS tubes protect electronic components from power fluctuations, electrostatic discharge and electromagnetic interference.

• In auxiliary equipment such as reversing radar, tachographs and car audio, TVS tube can also provide reliable overvoltage protection to ensure the normal operation of equipment.

4. Medical device field

TVS tubes also play an important role in the field of medical devices. For example:

• In medical equipment such as electrocardiograph, defibrillator and sphygmomanometer, TVS tubes can protect electronic components on the circuit board from overvoltage shocks caused by electrostatic discharge and power supply fluctuations, ensuring the accuracy and reliability of medical equipment.

V. Other areas

In addition to the above areas, TVS tubes are also widely used in:

• Lighting equipment: such as LED lights, energy-saving lamps, etc., to protect electronic ballasts and drive circuits.

• Industrial control: such as smart meters, industrial control instruments, etc., to protect precision measurement and control circuits.

• Consumer electronics: Portable devices such as MP3, MP4, game consoles, digital cameras, etc. protect the internal circuits from electrostatic discharge and power fluctuations.

Sum up

TVS tube with its small size, large power, fast response, no noise, low price and many advantages, in all areas of life have been widely used. It can not only protect electronic components from overvoltage impact, but also improve the stability and reliability of electronic equipment, bringing more convenience and safety to modern life.
