A diode is an electrical component that allows the current to flow in only one particular direction. Diodes are made up of silicon and germanium. They are used to protect the circuit by limiting the voltage and transforming the AC voltage into DC voltage. There are many types of diodes and each diode … Meer weergeven P-type and N-type semiconductor materials are made by process doping. This means that an impurity is introduced into the silicon … Meer weergeven The P-N junction diodes have two regions which are the P-type and N-type. The electrons will flow from the n-side to the p-side only when there is an increase in the voltage. Similarly, holes from the p-side will move to … Meer weergeven The most commonly used semiconductor diodes are the p-n junction diodes. p-n junction diodes are made by fusing p-type and n-type semiconductors. When both the semiconductors are fused a potential barrier … Meer weergeven Three types of biasing conditions can be obtained for p-n junctions when a voltage is applied. They are: 1. Zero Bias in which no external … Meer weergeven WebAs we know that a transistor is a combination of two diodes, we have two junctions here. As one junction is between the emitter and base, that is called as Emitter-Base junction and likewise, the other is Collector-Base junction. How many leads does a diode have? Diode Elements A diode has two leads connected to the external circuit.
WebIn this thyristor tutorial we will look at the construction and operation of the thyristor, or Silicon Controlled Rectifier, (SCR) in more detail. In many ways the thyristor is similar in construction to the transistor. It is a multi-layer semiconductor device, hence the “silicon” part of its name. It requires a gate signal to turn it “ON ... WebThe diode equation gives an expression for the current through a diode as a function of voltage. The Ideal Diode Law, expressed as: I = I 0 ( e q V k T − 1) where: I = the net current flowing through the diode; I0 = "dark saturation current", the diode leakage current density in the absence of light;
