Working Principles of J202_D74Z

J202_D74Z works on the principle of modulation of resistance. In order to use it, a small input signal must be applied to the gate terminal.This signal is called the Gate Signal, and it consists of a positive voltage and a negative voltage. The positive voltage is called the P-channel, while the negative voltage is called the N-channel.When the Gate Signal is applied, the N-channel is opened and the P-channel is closed. This leads to a rise in the resistance between the drain and the source terminals. At this point, the current flow is stopped and the transistor is in the off state.

On the other hand, when a negative voltage is applied to the gate terminal, the P-channel is opened and the N-channel is closed. This leads to a decrease in the resistance between the drain and source terminals. At this point, the current flow is resumed, and the transistor is in the on-state.
