TVS Parameters

1) V_RWM: Cut-off voltage, the highest operating voltage of TVS, the maximum dc or ac peak voltage that can be continuously applied without causing the deterioration or damage of TVS. Under V_RWM, TVS doesn't work.
2) V_C: Clamp voltage, the peak voltage measured at both ends of TVS when the peak pulse current I_PP of the specified waveform is applied.
3) V_BR: Breakdown voltage is the minimum avalanche voltage of TVS. Refers to the voltage measured at the two ends of TVS on the v-i characteristic curve under the specified pulsed dc current I_T or current close to avalanche.
4) I_R: Leakage current, also known as standby current. Under the specified temperature and maximum working voltage,  the maximum current flowing through TVS is measured at the cut-off voltage.
5) I_PP: Peak pulse current, usually the peak under the current waveform of 10 / 1000 μs.
6) I_T: Test current.
7) C: Capacitance value. For TVS at the same power level, the lower the voltage, the greater the capacitance. In the protection of communication lines, especially attention to the capacitance value of TVS.
8) Encapsulation: According to the encapsulated form of TVS, we can see the power. The chip area of TVS directly determines its power level.

TVS Application

Due to its advantages of extremely fast response speed, low clamp voltage, and accurate voltage, TVS is applied in fields with high requirements for protection devices, such as automotive electronics、home appliances、industrial control、 lighting、communication and medical industries, such as DC power cord、RS-485 interface、communication power supply、I/O port、etc.
