Field Effect Transistors (FET) - Technical MCQs

Q1:

When not in use, MOSFET pins are kept at the same potential through the use of:

A shipping foil

B nonconductive foam

C conductive foam

D a wrist strap

ANS:C - conductive foam

MOSFETS are quite sensitive. Even a human touch may generate static charge that may damage the MOSFET when not in use. Hence, a conducting foam is used to electrically short all the terminals of the MOSFET to get over any effect of static electricity by human touch.

*Non Conducting materials will not be able to short the terminals hence the damage chance is not minimized.
