The conversion of alternating current into direct current is known as rectification. The p type side is called the anode and the n type side is called the cathode. P N Junction Diode Baising And Its Vi Characteristics Low Power Pn Thz Mixer Diode Electronics Science And Printed Diodes Materials Processing Fabrication And As shown in the figure pn junction diode is a 2 terminal polarity sensitive device. Applications of pn diode . It is used in detector and demodulator circuits. Application of pn junction diode is a very vast topic itself. This page of application notes section covers pn junction diode applications. A rectifier diode is a two lead semiconductor that allows current to pass in only one direction. In this diodes tutorial we will see some of the common applications of diodes. The occurrence of an intrinsic layer can significantly i...
