P-N Junction Diode VI Characteristics in Forward and Reverse Bias

WebMay 6, 2016 · There are two important characteristics of an ideal diode: forward-biased and reverse-biased. "Reverse-biased" means that if there is a negative voltage (that is relative only to the direction of voltage flow indicated) being applied to the diode, there is no current flow and the diode acts as an open circuit, as shown in Figure 1.1 (C). WebMar 17, 2024 · A forward bias has an anode voltage that is larger than the cathode voltage. In contrast, a reverse bias has a cathode voltage that is larger than the anode voltage. A forward bias has a substantial forward current, while a reverse bias has a minimal forward current.
