MOSFET transistor trivia quiz questions with answers
What does MOSFET stand for?
Answer: Metal-Oxide-Semiconductor Field-Effect Transistor.
What type of semiconductor device is a MOSFET?
Answer: A transistor.
What is the function of a MOSFET?
Answer: To amplify or switch electronic signals.
What are the two types of MOSFETs?
Answer: Depletion mode and enhancement mode.
Which type of MOSFET operates with zero gate voltage?
Answer: Depletion mode.
What is the difference between a depletion-mode MOSFET
and an enhancement-mode MOSFET?
Answer: Depletion-mode MOSFETs conduct when the gate-source voltage is zero
or negative. Enhancement-mode MOSFETs only conduct when the gate-source
voltage is positive.
What is the symbol for a MOSFET?
Answer: A rectangle with three connections on top.
What are the three connections of a MOSFET?
Answer: Gate, drain, and source.
Which connection of a MOSFET controls the flow of
current between the other two?
Answer: The gate.
What is the threshold voltage of a MOSFET?
Answer: The minimum voltage required at the gate to turn the MOSFET on.
What is the drain-source on-resistance of a MOSFET?
Answer: The resistance between the drain and source when the MOSFET is fully
on.
What is the maximum voltage that can be applied between
the drain and source of a MOSFET?
Answer: The breakdown voltage.
What is the maximum current that a MOSFET can handle
before it is damaged?
Answer: The maximum drain current.
What is the difference between an N-channel MOSFET and
a P-channel MOSFET?
Answer: An N-channel MOSFET is made with an N-type semiconductor material,
while a P-channel MOSFET is made with a P-type semiconductor material.
What is the advantage of using a MOSFET over a BJT
(bipolar junction transistor)?
Answer: MOSFETs have a higher input impedance and consume less power than
BJTs.
What is the disadvantage of using a MOSFET over a BJT?
Answer: MOSFETs have a higher capacitance and are more susceptible to damage
from electrostatic discharge.
What is a power MOSFET?
Answer: A MOSFET designed for high voltage and high current applications.
What is a trench MOSFET?
Answer: A MOSFET with a trench structure in the semiconductor material to
reduce resistance and increase performance.
What is a double-diffused MOSFET (DMOS)?
Answer: A MOSFET with an additional diffusion process to create a P-type
region beneath the N-type channel to improve performance.
What is a superjunction MOSFET?
Answer: A MOSFET with an alternating P-N junction structure to improve
performance.
What is the gate-source capacitance of a MOSFET?
Answer: The capacitance between the gate and source of a MOSFET.
What is the Miller capacitance of a MOSFET?
Answer: The capacitance between the input and output of a MOSFET.
What is the body diode of a MOSFET?
Answer: A diode that is formed between the drain and source of a MOSFET.
What is the reverse recovery time of a MOSFET?
Answer: The time required for the body diode to turn off.
What is the maximum junction temperature of a MOSFET?
Answer: The temperature at which the MOSFET will be damaged.
