Thyristor A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. Silicon controlled Rectifier(SCR)…
Structure, operation and characteristics of PN junction diode
excess of electrons (N-type). It is a non-linear device. Structure In a p-type material, the hole is the majority carrier…
Structure Operation & characteristics of n-channel enhancement MOSFET
MOSFET is metal-oxide semiconductor Field Effect Transistor. Unipolar device MOSFET has majority carriers but no minority carriers. This is…
FET as Variable Resistor
Voltage-Controlled Resistance When a JFET operates in the ohmic region, it usually has VGS 5 0 to ensure hard saturation.…
FET is the preferred device for most switching applications. Why?
Because there are no minority carriers in an FET. As a result, it can switch off faster since no stored…
Zener as Regulator
Zener Regulator A zener diode is sometimes called a voltage-regulator diode because it maintains a constant output voltage even though…
