(A)Element 3-5 Semi-conductors

Question 1

What are the two most commonly used specifications for a junction diode?

Answer 1

Maximum forward current and Peak Inverse Voltage (PIV) how much current can pass and how much reverse voltage it can handle

Question 2

What limits the maximum forward current in a junction diode?

Answer 2

the junction temperature (heating up damages diode)

Question 3

MOSFETs are manufactured with THIS protective device built into their gate to protect the device from static charges and excessive voltages:

Answer 3

Zener diode (prevents zapping with zener)

Question 4

What are the two basic types of junction field effect transistors?

Answer 4

N-channel and P-Channel (PNP NPN)

Question 5

A common emitter amplifier has

Answer 5

more voltage gain than a common collector

Question 6

How does input impedance of a field effect transistor compare with that of a bipolar transistor?

Answer 6

FET has a high input impedance. bipolar transistor has low impedance
