In the circuit safety protection, it is very important to select a suitable transient voltage suppressor. TVS diode selection of popular science knowledge, here is not detailed, want to know you may wish to communicate with professional circuit protection device supplier Dongwo Electronics, anytime, anywhere for you to answer. When actually using TVS transient voltage suppressors, it is important to note that:

• The influence of ambient temperature and signal frequency on junction capacitance must be considered. As the operating temperature rises, the leakage current increases, the power decreases, and the breakdown voltage increases, especially the junction capacitance changes greatly with the temperature.

• The TVS tube manual gives only the absorbed power under a specific pulse width, but the pulse width in the actual line is unpredictable, which should be estimated in advance, and the wide pulse should be derated.

• In the protection of small current loads, it is necessary to consciously increase the current limiting resistance in the line;

• For the suppression of recurring transient voltages, particular attention should be paid to whether the steady-state average power of the transient voltage suppressor is within the safe range.
