Power diodes are generally
A. Silicon diodes
B. Germanium diodes
C. Either of the above
D. None of the above
Answer: Option A
Solution (By Examveda Team)
Power diodes are used in applications that require handling high currents and voltages.Germanium diodes have a lower breakdown voltage compared to silicon diodes.
This means they are not suitable for high-power applications where high voltages are involved.
Silicon diodes, on the other hand, have a much higher breakdown voltage and can handle significantly larger currents.
Therefore, power diodes are generally made from silicon because of its ability to withstand higher power levels.
Hence, the correct answer is Option A: Silicon diodes.
