Differences Between Junction Field Effect Transistor and Bipolar Junction Transistor

1. BJT is bipolar and JFET is unipolar.
2. BJT has low input impedance and JFET has high input impedance.
3. JFET has low power dissipation as compared to BJT.
4. JFET has low noise as compared to BJT.
5. BJT is current controlled device while JFET is voltage controlled device.
6. JFET is mostly used in digital circuits.
