What is TVS tube and what is its function?

TVS (Transient Voltage Suppressor) diode, also known as Transient Voltage Suppressor diode, is a new type of high-efficiency circuit protection component invented on the basis of Zener diode technology. The core advantages of TVS diode are p-second response time and high surge absorption ability.

The working principle of TVS diode is extremely similar to common Zener diodes. Within a certain range, it can limit the voltage at both ends of the circuit, so that the voltage clamp between the two poles is stable at a safe value, effectively protecting the precision components in the circuit from damage caused by high voltage, high current, and high surge. At present, TVS diodes are widely used in household appliances, computer systems, communication equipment, automotive electronics, AC/DC power supplies, electronic ballasts, industrial control, medicine, aviation, and other fields.
