Forward and reverse biased
WebA Zener diode operates just like a normal diode when it is forward-biased. However, a small leakage current flows through the diode when connected in reverse-biased mode. As the reverse voltage increases to the predetermined breakdown voltage (Vz), current starts flowing through the diode. WebDevices typically operate in steady state and are either in forward or reverse bias. 3. Transient. If the applied voltage changes rapidly, there will be a short delay before the solar cell responds. As solar cells are not used for high speed operation there are few extra transient effects that need to be taken into account. Diodes under Forward ...
