Diode saturation current and temperature
WebSep 6, 2024 · Saturation current in diode. I don't quite get why there should be a saturation current in a PN junction diode in reverse bias. The electrons in the N side should be pulled toward the battery, and the battery allows electrons to flow toward the P side. These electrons should now travel through the electric field of the depletion region … WebAnswer: I don’t know what a normal diode is, but all diodes suffer key parameteric changes from temperature variations. * A lot of the electrical characteristics useful for most people can be directly derived from this: thermal voltage Vt=kT/q Shockley diode equation - Wikipedia temperature wil...
