What is a transient suppression diode? What are the functions of transient suppression diodes? Transient suppression diode is a new product developed on the basis of the voltage regulator process, its circuit symbol is the same as the ordinary voltage regulator diode, the shape is also the same as the ordinary diode, when the TVS tube at both ends of the instant high energy impact, it can at a very high speed (up to 1*10-12 seconds) to make its impedance suddenly reduced, while absorbing a large current, The voltage between the two ends is clamped to a predetermined value, thus ensuring that the circuit elements behind are protected from damage by the impact of transient high energy.
1. What is a transient suppression diode
Transient suppression diode (TVS) tube. Is a high-performance protection device, when the TVS diode under high transient energy shock, it can absorb the surge current at the speed of microseconds. Voltage, protection of electrical equipment. TVS tube size is small. Fast reaction time and other characteristics. In anti-lightning, anti-overvoltage, anti-static, anti-interference household appliances. Instruments. Communication equipment, computers, security, satellite guidance and other equipment widely used.
2. The role of transient suppression diode
Transient suppression diode action, that is, TVS(Transient Voltage Suppressors) transient suppression diode working principle. TVS transient suppression diode is a new type of high-efficiency circuit protection components invented on the basis of Zener diode process, also known as TVS tube, transient suppression diode, transient voltage suppressor, avalanche breakdown diode, etc., there are one-way and two-way points. When the two ends of the TVS diode are subjected to instantaneous high energy impact, it changes the impedance value between the two ends from high impedance to low impedance at the speed of PS seconds to absorb an instant large current, and the voltage at both ends is clamped on a predetermined value, thus protecting the precision components behind from the impact of transient high voltage peak pulses.
3. Transient suppression diode application
Transient suppression diode is widely used in sensitive electronic parts overvoltage protection due to its advantages of PS level response speed, large transient power, low leakage current and capacitance, easy control of clamp voltage, small breakdown voltage deviation, high reliability, small size and easy installation. TVS diodes can be seen in automotive electronics, consumer electronics, industrial equipment, household appliances, communication equipment and other fields.
