* Question
| What parts of the volt-ampere characteristic curve of the diode can be divided into? |
* Answer
| (1) Forward characteristic part 1 Forward voltage: When the positive pole of the diode is applied with a high potential and the negative electrode is low, the voltage is called a forward voltage.
2 Forward characteristics: that is, the characteristics exhibited by the diode when the forward voltage is applied, as shown in the right E half of the 5.2BC (ie, the OABC segment).Therefore, there is still no current (dead zone voltage: 0.2 to 0.3V for the manifold; 0.5 to 0.7V for the silicon tube).When the forward voltage exceeds the deadband voltage, as long as the voltage rises slightly, the current will increase sharply. (3) Reverse breakdown characteristic portion When the reverse voltage is increased by N-4, the reverse current sharply increases.If the reverse current increases to a certain value, the diode will thermally break down, and a strong port means permanent damage. |
