The depletion mode MOSFET shown as a N channel device (P channel is also available) in Fig. 4.4.1 is more usually made as a discrete component, i.e. A single transistor rather than IC form. In this device a thin layer of N type silicon is deposited just below the gate-insulating layer, and forms a conducting channel between source and drain.

Depletion Mode Mosfet Applications

The n-channel MOSFET operates in the depletion mode when a negative gate-to-source voltage is applied and in the enhancement mode when a positive gate-to-source voltage is applied. These devices are generally operated in the depletion mode. Depletion Mode MOSFET N-Channel IXTT16N10D2 IXTH16N10D2 V DSX = 100V I D(on) 16A R DS(on) 64m Features. Normally ON Mode.

D-MOSFET “Depletion MOSFET” Depletion MOSFET or D-MOSFET is a type of MOSFET where the channel is constructed during the process of manufacturing. Therefore, the D-MOSFET can conduct between its drain and gate when the V GS = 0 volts. Therefore, D-MOSFET is also known as normally ON transistor.

Hello, I'm searching for a depletion (normally-ON) which can work under 9V/5V Vds (3.2V would also be nice but not required).The Vgs threshold should be around 1-3V for 9V, 1-1.5V for 5V.Unfortunately I only seem to find components that work with VDS ~25V or more… do you know if anything like what I need exists? It would be best in a packaging suitable for breadboard prototyping, but at the moment I'm open to any packaging.

In case you think this is not possible, do you think there can be another way to arrange this kind of normally-on switch?

Thanks for your time! And forgive my noobness :)
