FAQ about TVS - Diodes
-
1. What does a TVS diode do?
The main function of TVS diodes (Transient Voltage Suppression Diodes) is to protect electronic equipment from voltage spikes and surge voltages. When the two poles of the TVS diode are impacted by reverse transient high energy, it can change the high impedance between the two poles into low impedance within 10^-12 seconds, while absorbing surge power up to several kilowatts, causing the gap between the two poles to The voltage is clamped to a safe value, thereby effectively protecting precision components in electronic circuits.
The specific working principle of TVS diodes is as follows:
Absorb surge power: TVS diodes can, under reverse application conditions, when subjected to a high-energy large pulse, their working impedance immediately drops to a lower conduction state, allowing large current to pass while clamping the voltage at predetermined level. Its response time is only 10^-12 seconds.
Protection circuit: TVS diodes are used in parallel with the protected circuit. When the circuit is working normally, the TVS diode is in a high impedance state and does not affect the circuit; when there is a surge voltage impact, the TVS diode conducts quickly, absorbs the surge energy, and protects the subsequent circuit.

2. Are TVS diodes and Zener diodes the same?
TVS diodes and Zener diodes have significant differences in functionality and characteristics, so they are not identical.
Definition and purpose
Zener diode: Zener diode is a diode that uses a PN junction for reverse breakdown. It is mainly used to ensure voltage stability. It has a high resistance state before the reverse breakdown voltage and is in a low resistance state after exceeding this critical point. It is widely used in various voltage stabilizing circuits and reference voltage components.
TVS Diode: TVS diode (Transient Suppression Diode) has surge absorption capability and is mainly used to protect circuits from damage caused by transient high voltages such as surges and electrostatic discharge (ESD). It can absorb a large amount of instantaneous current and voltage in a short period of time, protecting the subsequent equipment or circuits from damage.

3. How fast are TVS diodes?
TVS diodes are very fast and can respond within 10^-12 seconds (i.e. 1 nanosecond). When the two poles of the TVS diode are impacted by reverse transient high energy, it can change the high impedance between its two poles into low impedance in a very short time, while absorbing surge power up to several kilowatts, reducing the voltage between the two poles. It is clamped to a predetermined safe value, thereby effectively protecting precision components in electronic circuits from damage by various surge pulses.
This fast response characteristic of TVS diodes allows them to play an important role in various electronic systems, especially where precision electronic components need to be protected from transient voltage impacts. For example, in the fields of computer systems, communication equipment, automotive electronics, household appliances, etc., TVS diodes are widely used to protect circuits from electrostatic discharge, surge voltage, and electromagnetic interference.
