1. Junction Diodes

- P-N Junction Diode: Basic diode with a P-type semiconductor and an N-type semiconductor
- Schottky Diode: Metal-semiconductor junction with very low forward voltage drop
- Zener Diode: Designed to break down under high reverse voltage without damage

2. LED (Light Emitting Diode)

- Emits light when forward-biased
- Common types include visible, infrared, and ultraviolet LEDs

3. Photodiode

- Converts light into electrical current
- Used in photo detectors, solar cells, and fiber optics

4. Laser Diode

- Emits a highly focused beam of coherent light
- Used in lasers, optical communications, and laser pointers

5. Varactor Diode

- Voltage-dependent capacitor
- Used for frequency tuning, voltage regulation, and parametric amplification

6. Tunnel Diode

- Very high peak current with a negative resistance region
- Used in high-speed switching applications

7. Gunn Diode

- Solid-state microwave oscillator
- Generates microwaves with high power and efficiency

8. IMPATT Diode

- Impact Ionization Avalanche Transit-Time Diode
- Generates high-power microwaves

9. PIN Diode

- Intrinsic semiconductor region between P and N regions
- Used as high-power RF switches, attenuators, and modulators

10. Step Recovery Diode

- Rapid recovery time from reverse bias
- Used for generating short pulses

11. Super Barrier Diode
