In the next tutorial about diodes, we will look at the small signal diode sometimes called a switching diode which is used in general electronic circuits. What is the forward resistance of the PIN diode? This electric field assists in speeding up of the moving of charge carriers from P to N region, which consequences in quicker operation of the PIN diode, making it an appropriate device for high frequency operations. Ans: For low-frequency model, there is a decrease in resistance and increase in reactance. A PIN diode is different from a normal diode because it consists There is a set of stored charge in the intrinsic region. Required fields are marked *. These key PIN diode characteristics include the following: Low capacitance: Again the intrinsic layer increases the depletion region width. The Diode obeys standard diode equation for all the low-frequency signals. (i) Reverse current-Illumination curve. Likewise the N-region has been doped to hold excess electrons.
