What is Depletion Mode MOSFET : Working & Its Applications
What is Depletion Mode MOSFET? A MOSFET that normally turns ON without applying any gate voltage when you connect is known as a depletion mode MOSFET. In this MOSFET, the flow of current is from the drain terminal to the source. This type of MOSFET is also known as normally on the device. Once a voltage is applied at the gate terminal of the MOSFET, the drain to the source channel will become more resistive. When the gate-source voltage enhances more the flow of current from the drain to the source will reduce until the flow of current from the drain to the source stops.

In these MOSFETs, the arrow symbols represent the type of MOSFET like P-type or N-type. If the arrow symbol is inside direction then it is n-channel and if the arrow symbol is outside, then it is p-channel. Depletion MOSFET Symbols How Do...
