Working Principles

The IRFL210 operates based on the principle of field-effect modulation. When a voltage is applied to the gate terminal, it creates an electric field that controls the conductivity of the channel between the drain and source terminals. This modulation of conductivity allows the FET to act as an amplifier or a switch in electronic circuits.
