Information of TVS The transient Voltage Suppressor, referred to as TVS, the TVS operates by shunting excess current when the induced voltage exceeds the avalanche breakdown potential. It is a clamping device, suppressing all over voltages above its breakdown voltage. It automatically resets when the overvoltage goes away, but absorbs much more of the transient energy internally than a similarly rated crowbar device. The selection tips of TVS 1. The Vrwm of TVS should be more than 10% working voltage and tolerance, that protect the Max DC or continuous working voltage of circuits. If the Vrwm is too low, the device will affect the normal work of the circuits because of the snow slide or reverse electric leakage. The current will be divided in the parallel circuit and the voltage will be divided in the serial circuit. 2. The VC of TVS should be less than the damaged voltage of protecting circuits. 3. The Ppp of TVS should be more than the possible peak pulse of protecting circuits. 4. The Ipp of TVS should be more than the surge current of transient circuit. 5. For the lightning protection of data interface circuit, the semiconductor ESD of low capacitance is better. 6. The selection of TVS’ polarity and encapsulation structure should based the application. For the AC circuit, the dual polarity TVS is better, and for the Multi-line protection, the ESD array of semiconductor is better. |
