Sr.No. D-MOSFET E-MOSFET
1. It is called as Depletion MOSFET, because of depletion of channel. It works only in Enhancement mode, hence called as Enhancement MOSFET.
2. n-type semiconductor exists between source and drain in construction itself. n-channel doesn't exist between sources and drain.
3. When Vgs = 0V, Ids flows due to Vds. When Vgs = 0V, Ids = 0 though Vds is applied.
4. It can be used as E-MOSFET. It can not be used as a D-MOSFET.
5. Does not occur At Vgs = Vt, MOSFET becomes ON.
