| MOSFET | JFET |
|---|---|
| The MOSFET is the abbreviation of metal oxide semiconductor field effect transistor. | The JFET is the abbreviation of junction field effect transistor. |
| The MOSFET has only one p-n junction. | It has two p-n junctions. |
| Drain resistance is high. | Drain resistance is low. |
| MOSFETs can be operated in either depletion or in enhancement mode. | The JFETs can be operated in the depletion mode. |
| The MOSFET is good for high noise applications, switching applications etc. | The JFET is good for low noise application, low capacitance and high resistance input. |
| It has very high input impedance. | It has high input impedance. |
| The MOSFET have insulated gate structure. | The JFET does not have insulated gate. |
| It has reverse body diode. | It has no reverse body diode. |
