Shockley diode equation (in real transistors)
Description
In electronics, a diode is a two-terminal electronic component with asymmetric conductance; it has low (ideally zero) resistance to current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. The Shockley diode equation or the diode law gives the I–V characteristic of a diode in real transistors, in either forward or reverse bias (or no bias).
