How many junctions does a diode have
WebThe diode equation gives an expression for the current through a diode as a function of voltage. The Ideal Diode Law, expressed as: I = I 0 ( e q V k T − 1) where: I = the net current flowing through the diode; I0 = "dark saturation current", the diode leakage current density in the absence of light; WebFor example, a common type of transistor, the bipolar junction transistor (BJT), consists of two p–n junctions in series, in the form n–p–n or p–n–p; while a diode can be made from …

Web27 jul. 2015 · Ok, there are many things at play here. Let me just quickly define a few things for you. I'm assuming some background knowledge since you mentioned the Shockley equation. A diode is formed by joining a piece of n-type and p-type semiconductor. This leads to diffusion of electrons and holes which creates a current. WebHow many junction/s do a diode consist? a) 0 b) 1 c) 2 d) 3 View Answer 2. If the positive terminal of the battery is connected to the anode of the diode, then it is known as a) Forward biased b) Reverse biased c) Equilibrium d) Schottky barrier View Answer 3. During reverse bias, a small current develops known as a) Forward current
