Question

Write three merits and de-merits of Semiconductor devices.

Answer 1

➡️ Disadvantages of diode:⬅️


1. They are extremely heat sensitive.


2. They can handle small current and low inverse voltage.


3. They can handle small current and low inverse voltage.


4. They can’t be an overload even for a short period of time. 


The slight overload can permanently damage the diode.


➡️Advantages of diode:⬅️

 

1. They are smaller, more ruged and have a longer life.


2. They are simpler and inherently cheaper.


3. They require no filament power. So they produce less heat than the equivalent vacuum-tubes. 


Hope it helps ❤️

Answer 2

Disadvantages of Semiconductor Devices:

. The noise level is higher in semiconductor devices as compared to that in the vacuum tubes.

. Ordinarysemiconductor devices cannot handle as more power as ordinary vacuum tubes can do.

. In high frequency range, they have poor responder.


Advantages of Semiconductor Devices:

. As semiconductor deviceshave no filaments, hence no power is needed to heat them to cause the emission of electrons.

. During operation, semiconductor devices do not produce any humming noise.

. Semiconductor devices require low voltage operation as compared to vacuum tubes.
