Explain Transistor Current Components: The various transistor current components which flow across the forward-biased emitter junction and reverse biased collector junction are indicated in Fig. 10.11. The current flowing into…
Point Contact Diode Construction and Working: The point contact diode is basically constructed by touching a metallic whisker to an exposed surface of an N-type semiconductor substrate. The semiconductor used…
Zener Diode Application: Zener diodes have numerous applications in transistor circuitry. Some of their common Zener Diode Application are explained below. 1. Zener Diode as a Voltage Regulator:Â Voltage regulation is…
Construction and Working of Zener Diode: Zener diode, also sometimes called the breakdown diode, is a P-N junction diode specially designed for operation in the breakdown region in reverse bias…
What is Diode Resistance? What is Diode Resistance? - As already discussed, a forward-biased diode conducts easily whereas a reverse-biased diode restrains the flow of current, so a diode has…
Determination of Diode Characteristics: Determination of Diode Characteristics - The forward characteristics of a diode can be obtained by use of the circuit depicted in Fig. 7.16 (a). The diode…
Diode Failure Modes and Causes: We would certainly like for solid-state components to be 100% reliable but this is unfortunately not true. All solid-state devices have a certain probability of…
Zero bias PN junction: Zero bias PN junction - Here we will examine the properties of the step junction in thermal equilibrium, where no currents exist and no external excitation…
