Diode Technology Fundamentals Quiz

This quiz covers fundamental concepts and applications of various semiconductor diodes. Questions range from basic diode operation and characteristics (e.g., p-n junction behavior, rectification) to specific types of diodes like Zener, LED, Schottky, Photodiode, Varactor, and Tunnel diodes, and their unique features and uses. Topics include diode equations, physical principles of operation, and key parameters like Peak Inverse Voltage (PIV) and ideality factor. A solid understanding of these topics is essential for students in electronics and related engineering fields.

Key Formulae (where applicable):

• Shockley Diode Equation: $I_D = I_S \left( e^{\frac{V_D}{nV_T}} - 1 \right)$

  where $I_D$ is diode current, $I_S$ is reverse saturation current, $V_D$ is diode voltage, $n$ is the ideality factor, and $V_T$ is the thermal voltage.

• Thermal Voltage: $V_T = \frac{kT}{q}$

  where $k$ is Boltzmann's constant ($1.38 \times 10^{-23} \text{ J/K}$), $T$ is temperature in Kelvin, and $q$ is the elementary charge ($1.602 \times 10^{-19} \text{ C}$).
