How does a diode change the current?
2020/10/30Don't underestimate a diode. Although the principle of the diode is very simple, its role in the circuit is very large, and the use of the diode in the circuit is also very wide. The diode belongs to a PN junction, the most basic characteristic is unidirectional conductivity, forward conduction, reverse cut-off. The following picture shows some common diodes. A single diode has only two useful pins. A diode packaged with more than three pins may have multiple diodes integrated inside or some pins may be left floating.
