Transient voltage suppressor is what?

Transient Voltage Suppressor (Transient Voltage Suppressor) TVS for short, is a diode in the form of highly efficient protection device, some in the literature for TVP, AJTVS, SAJTVS etc. When the poles TVS diode reverse transient high-energy impact, it can, at the rate of 10-12 seconds between the poles of high impedance is a low impedance, absorb as much as several kilowatts of power surge, the voltage between the poles clamp which is located in a predetermined value, effectively protect the electronic line of precision components, from the damage of all kinds of surge pulse.

Because it has a fast response time, the transient power, low leakage current, low breakdown voltage deviation, clamping voltage control more easily and without damage to the limit, the advantages of small volume, at present has been widely used in computer systems, communications equipment, power supply, household appliances and other fields.

1, the TVS diode is placed between the signal lines and grounding, can prevent and control data bus is affected by the noise don't want to.

2, electrostatic discharge effect can release more than 10000 v, 60 more than a pulse, and lasts 10 ms; And the general TTL devices, with more than 30 ms 10 v pulse, will lead to damage. Use TVS diode, which can effectively absorb can cause pulse device damage, and can eliminate the interference caused by switching between bus.

3, add TVS diode on the signal and the power cord, can prevent the microprocessor or microcontroller for the moment's fat, such as electrostatic discharge effect of surge and switch power supply, communication power supply noise caused by the failure.
