Write the
full form of PUT.
|
|
PUT : Programmable Unijunction Transistor
|
2
|
Write the full form of CSCR.
|
|
CSCR : Complementary silicon
controlled rectifier
|
3
|
Describe the main features of the PUT.
|
|
The main feature of the PUT is that
its triggering voltage VP can set by external circuit.
|
4
|
How many junction the PUT consists of?
|
|
Three junction
|
5
|
Describe the advantages of PUT over
UJT.
|
|
Advantages
of PUT
- The triggering voltage can be set by
external circuit.
- Low peak voltage as compared to UJT
|
6
|
Why the PUT is called as complementary
SCR?
|
|
- The gate of the PUT is connected to
anode side whereas it is connected to cathode side in the SCR therefore it is
also called as complementary SCR.
|
7
|
Why the value of the capacitor in the
PUT relaxation circuit is kept as low as possible?
|
|
- The value of the capacitor in the PUT
relaxation oscillator circuit is kept as low as possible because large value
of capacitor requires electrolytic capacitor which suffers from high leakage.
