Here are some characteristics of a semiconductor diode:

Unidirectional current flow: A semiconductor diode allows current to flow in only one direction, from anode to cathode.
Low resistance: Diodes have low resistance to the flow of current. They have high resistance at one end and low resistance at the other end.
Current rise: The current rises to a stable voltage, also known as knee voltage, in a linear manner. After reaching this voltage, the current does not follow the linear motion.
Reverse current: The reverse current does not depend on the reverse voltage.
Voltage drop: A silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V.
