Diode Types Of Diodes Electronics Basics Rohm. by John Ardizzoni Download PDF PIN diodes, which sandwich a lightly doped intrinsic (I) region between heavily doped P and N regions, are used extensively in RF and microwave applications.Common applications of PIN diodes are microwave switches, phase shifters, and attenuators, where high isolation and low loss are required. Current is the dependent variable while voltage is the independent variable in the Schottky diode. So let’s begin. The symbol of zener diode is similar to the normal p-n junction diode, but with bend edges on the vertical bar. PIN diode is formed by sandwiching intrinsic layer (high resistivity about 0.1 Ω-m) between P-type and N-type semiconductor in order to create an electric field between them. The PiN diode is simulated using V-TCAD software. This layer is very lightly doped, almost intrinsic and hence the device is also known as a PIN diode, where i stands for intrinsic.
