Saturation Current Density in Opto Electronics Devices Formulas

Saturation Current Density is the current flow per unit area of the pn junction when a few volts of reverse bias is applied to the junction. And is denoted by J₀. Saturation Current Density is usually measured using the Ampere per Square Meter for Surface Current Density. Note that the value of Saturation Current Density is always positive.
