Field Effect Transistors (FET) - Technical MCQs

Q1:

When is a vertical channel E-MOSFET used?

A for high frequencies

B for high voltages

C for high currents

D for high resistances

ANS:C - for high currents

Vertical channel Mosfets are most commonly used in power applications and in power applications they deal with high levels of current. By using a vertical channel E-MOSFET can be designed to have shorter and wider channel with less resistance between the drain and source thus more current can flow.
