SMD Transient Voltage Suppressors
Information for Designer
When selecting the TVS for designing within the circuit, some characteristic parameter should
be considered carefully to meet the circuit condition. The following guideline are recommended.
1. The surge handling ability of the selected TVS should meet the need of dissipating the
expected transient surge current of the protected circuit.
2. The clamping voltage of the selected TVS should be less than the maximum allowed
operating voltage of the protected circuit.
3. In high speed data transmission situation. the capacitance of the selected TVS should be
considered.
4. The special requests of the TVS’s capacitance such as ESD prevention are available, please
contact with us.
5. While choosing the TVS, the working voltage of the TVS should be greater than or equal to
the normal operating voltage of the circuit.

6. Protection Principle : When the voltage increase above the threshold of the varistor, the suppressor
draws a rapidly increasing current. The the overvoltage is considerably attenuated.
