How to distinguish the positive and negative poles of TVS Transient-voltage-suppression

How to distinguish the positive and negative poles of TVS Transient-voltage-suppression diode and the single and double directions of TVS Transient-voltage-suppression diode?

When the Transient-voltage-suppression diode is in your hands, you should first know the positive and negative poles of the TVS Transient-voltage-suppression diode and the one-way and two-way TVS Transient-voltage-suppression diode.

1. See TVS Transient-voltage-suppression diode logo. TVS Transient-voltage-suppression diode can be divided into one-way and two-way. One end of one-way TVS Transient-voltage-suppression diode has a thin colored ring connected to the positive pole; There are two loops in the middle of the bidirectional TVS Transient-voltage-suppression diode or there is no sign and no polarity.

2. Refer to the specification to distinguish the positive and negative poles of TVS Transient-voltage-suppression diode and the single and double directions of TVS Transient-voltage-suppression diode.

3. See TVS Transient-voltage-suppression diode model. The naming of TVS Transient-voltage-suppression diode models is regular, and most TVS Transient-voltage-suppression diode models can see the parameters.

4. With the help of a multimeter tool: there is voltage on one side in one direction, and avalanche breakdown characteristics on the DC side; There is voltage in both directions, and in terms of DC, it is symmetrical in both directions.
