1N4007 is a general silicon rectifier diode, which is packaged in the form of DO-41 and SMA. It is widely used in various AC-to-DC rectifier circuits, and can also be used in bridge rectifier circuits.
SMD diodes have replaced traditional lead products in most applications. Among them, SOD package is the installation form of most SMD diodes.
MOS transistor VGS(th) (turn-on voltage)
The input impedance is very high, because the gate of MOS tube has insulating film oxide, which can even reach hundreds of millions of ohms, so its input draws almost no current and can be used as an electronic switch.
MOS FET is also called MOS FET, which is the abbreviation of metal-oxide-semiconductor field-effect transistor.
To answer this question, we need to first understand the working principles of light-emitting diodes and digital diodes.
