Questions with TVS - Diodes

  • Ask: How do TVS diodes work?

    Answer: TVS diodes are constructed with large cross sectional area junctions for absorbing high transient currents. ... As a result, the transient current is diverted away from the protected components and shunted through the TVS diode. The voltage across the pro- tected circuit is limited to the clamping voltage of the TVS diode.

  • Ask: How do I identify a TVS diode?

    Answer: A TVS diode can be tested on the diode test range of a digital multimeter. It will have a low resistance in the forward direction, and a high resistance in the reverse direction. However, an in-circuit test will be complicated by the fact that the diode is connected directly across a particular supply rail.

  • Ask: Does TVS diode have polarity?

    Answer: Figure 1 shows a positive and negative transient at the input of a device pro- tected by a unidirectional TVS diode. During a transient's positive cycle, the TVS diode junction is reversed biased.

  • Ask: What is clamping voltage of TVS diode?

    Answer: Transient Voltage Suppressors (TVS) limit voltage spikes to an acceptable level through clamping. A clamp device begins conducting when its threshold voltage is exceeded, then restores to a non-conducting mode when the voltage drops below the threshold level.
