electronic component diodes

 

Diode is widely used as a rectifier of AC power into DC and many  applications in electrical engineering and electronics. Diode has two legs, namely Anode  and cathode. To find out how to work as a rectifier diode we see two series diode connected to Diode circuit shows positive DC voltage is connected Cathode footed, looked no current flows or Diode in a position to block the flow, This condition is called fallback position (reverse). Characteristics of a Diode illustrated by the horizontal axis to voltage (Volt). The vertical axis to show the current (mA until Amperes). Positive voltage (forward) calculated from zero to the right axis. Negative voltage (reverse) begins negative axis to the left. Current line forward (forward) axis starts from zero and above by units of Ampere. Current line backward (reverse) axis begins with zero down to the order of mA. Diode has a reverse voltage withstand limits on certain value. if Diode reverse voltage is exceeded it will be permanently damageda DC voltage source. Diode circuit with a source DC voltage showed a positive DC voltage Anode is connected to the leg, the This condition Diode DC current drain can be seen from the appointment ampermeter with the flow If, for voltage is called the forward voltage Uf (forward). Silicon diode will begin forward when it has reached a voltage cut-in of 0.7 volts, for Diode germanium cut-in voltage of 0.3 Volt.

semiconductor materials

In the knowledge of electrical engineering materials are known three types of material, ie material conductor, semiconductor materials and insulator materials. Conductor materialshaveproperties of high electrical leads, the conductor material used for cable or wireconductor of electricity, like copper, aluminum, iron, steel, etc.. materialsemiconductor properties can be conductive or it can also have propertiesinhibit the electrical current depends on the condition given external voltage, the semiconductor material is a component manufacturingTransistor, Diode, thyristor, triac, GTO
Some semiconductor materials are silicon (Si), germanium (Ge), gallium arsenic(GeAs), indium antimonid (InSb), cadmium sulfid (CdS) and siliciumcarbid (SiC),etc.. Insulator material has good electrical properties inhibit, used as insulators inelectrical equipment, for example ceramics, porcelain, PVC, paper, etc.. Electronic components are widely used in the electrical engineering industry is the thyristor
