Before revision: The Shockley diode equation or the diode law, named after transistor co-inventor William Shockley of Bell Labs, models the exponential current–voltage (I–V) relationship of semiconductor diodes in moderate constant current forward bias or reverse bias: where is the diode current, is the reverse bias saturation current (or scale current), is the voltage across the diode, is the thermal voltage, and is the ideality factor, also known as the quality factor or emission coefficient.
