WebThe 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 the n-side only when the voltage applied to the P-type material is increased. WebThe silicon-controlled rectifier is like a junction transistor with a fourth layer and therefore three p-n junctions.The two outer junctions are forward biased by the voltage as shown, but the inner junction is reverse biased.A small current in the gate electrode can turn on the current, and it will stay on until the driving voltage is removed.
