Distinction between positive and negative poles of TVs transient voltage suppression diode
How to distinguish the positive and negative poles of TVs transient voltage suppression diode from the one-way and two-way poles of TVs transient voltage suppression diode?
When the transient voltage suppression diode is in your hand, you should first know the positive and negative poles of TVs transient voltage suppression diode and the one-way and two-way of TVs transient voltage suppression diode.
1. Look at the TVS transient voltage suppression diode flag. TVs transient voltage suppression diode can be divided into unidirectional and bidirectional. One end of unidirectional TVs transient voltage suppression diode has a fine color ring, which is connected to the positive pole; There are two rings in the middle of the bidirectional TVs transient voltage suppression diode, or there is no sign and no polarity.
2. See the specification to distinguish the positive and negative poles of TVs transient voltage suppression diode and the one-way and two-way of TVs transient voltage suppression diode.
3. See TVs transient voltage suppression diode model. The model naming of TVs transient voltage suppression diode is regular, and the parameters can be seen in most TVs transient voltage suppression diode models.
4. With the help of multimeter tools: there is voltage on one side in one direction and avalanche breakdown characteristics in DC; There is voltage in both directions. In terms of DC, it is symmetrical in both directions.
