Transient suppression diode

Transient voltage suppression diode is a new product developed on the basis of Zener tube technology. Its Circuit symbol is the same as that of ordinary Zener diode, and its shape is the same as that of ordinary diode. When both ends of the TVS tube experience instantaneous high-energy impact At the same time, it can suddenly reduce its impedance at a very high speed (up to 1*10-12 seconds), and at the same time absorb a large current, clamp the voltage between its two ends to a predetermined value, thereby ensuring the back The circuit components are protected from damage caused by transient high-energy impacts.

1. What is a transient suppression diode

Transient voltage suppression diode is abbreviated as TVS tube. It is a high-performance protection device. When TVS diode is subjected to high transient energy impact, it can absorb surge current and voltage at a microsecond speed to protect electrical equipment. The TVS tube is small in size. Features such as fast response time. Widely used in anti-lightning, anti-overvoltage, anti-static, anti-interference household appliances, instrumentation, communication equipment, computers, security, satellite navigation and other equipment.

2. The role of transient suppression diodes

The role of transient suppression diodes is the working principle of TVS (Transient Voltage Suppressors) diodes. Transient suppression TVS diode is a new type of high-efficiency circuit protection component invented on the basis of Zener diode technology, also known as TVS tube, transient voltage suppression diode, transient suppression diode, transient voltage suppressor, avalanche breakdown diode And so on, there are one-way and two-way points. When the two ends of the TVS diode undergo an instantaneous high-energy impact, it changes the impedance between the two ends from high impedance to low impedance at a speed of PS seconds, so as to absorb an instantaneous large current and clamp the voltage between its two ends. A predetermined value, so as to protect the precision components behind from the impact of transient high-voltage spikes.

3. Transient suppression diode applications

Transient suppression diodes are widely used in sensitive electronics with the advantages of PS-level response speed, large transient power, low leakage current and capacitance, easy control of clamping voltage, small breakdown voltage deviation, high reliability, small size, and convenient installation. In the overvoltage protection of parts, TVS diodes can be seen in the fields of automotive electronics, consumer electronics, industrial equipment, household appliances, and communication equipment.
