What is Semiconductor Diode?

What is Semiconductor Diode?: The Semiconductor Diode (Silicon Rectifier) described here in Fig 11.2(a) are based on the property of p-type and n-type materials in conjunction. An ideal diode presents zero impedance to current flow in one direction and infinite impedance in the opposite direction. A practical diode has a very low forward resistance and …
