TYPES OF DIODES

TYPES OF DIODES

1. ZENER DIODE

   • It acts as a voltage regulator or stabilizer.

2. LED DIODE

   • It is mainly used in applications such as aviation lighting, traffic signs, camera flashes etc.

3. CONSTANT CURRENT DIODES

   • It functions as a two terminal current limiter to achieve high output impedance.

4. SCHOTTKY DIODE

   • these are used in high frequency rectifier applications.

5. SHOCKLEY DIODE

   • They are applied as trigger switches for SCR and act as a relaxation oscillator.

6. TUNEL DIODE

   • Used as a high speed switch.

7. VARACTOR DIODE

   • It acts as a variable voltage capacitor. It is used in applications such as voltage controlled oscillators.

8. PIN DIODE

   • act as range shift inductors in low phase noise oscillators.
