P-N Junction Diode Calculator & Formula : Shockley Tool

A P-N junction diode is a basic semiconductor device that allows current to flow in one direction while blocking it in the opposite direction. Its behavior is governed by the Shockley diode equation, which relates diode current to applied voltage and temperature. The P-N Junction Diode Calculator uses this fundamental relationship to help users analyze diode current, forward voltage drop and operating conditions with ease.
