The transistor switch Flashcards
1
Q
When a silicon transistor is considered to be completely turned on, how much voltage is dropped across the collector-emitter section?
A
0.7 voltage drop
2
Q
When a transistor is driven into saturation, how much volage is dropped across the collector emitter section
A
0.3 voltage drop
3
Q
How is a transistor driven into saturation ?
A
Increased base current (IB) that is needed for normal operation.
4
Q
why is it desirable to drive a transistor into saturation when it is used for switching?
A
produce less heat.
5
Q
DIsadvantage of driving transistor into saturation?
A
frequency response reduced
