WebThe forward bias operation in the Zener diode is the same as in any normal diode. In reverse bias, the diode does not allow current (but only a small leakage current) until the voltage reaches the Zener breakdown voltage. In this region, the current through the diode flows in the reverse direction. ... (BJT) Construction, Working, Types and ... WebJFET or Junction Field Effect Transistor is one of the simplest types of field-effect transistor. Contrary to the Bipolar Junction Transistor, JFETs are voltage-controlled devices. In JFET, the current flow is due to the majority of charge carriers. However, in BJTs, the current flow is due to both minority and majority charge carriers.
