🔹 1. Diode Kya Hota Hai?

Diode ek semiconductor device hai jo electric current ko sirf forward direction me flow karne deta hai aur reverse direction me rokta hai.

⚙ Structure:

Diode do part se milke banta hai: P-type aur N-type material.

Dono ke junction ko PN-junction kehte hain.

➕ Forward Bias:

Jab positive terminal P-side se judta hai aur negative terminal N-side se – tab diode current pass karta hai.

➖ Reverse Bias:

Agar polarity ulti ho jaaye to diode current block kar deta hai.

🔹 2. Diode Ke Prakar (Types of Diode):

🧩 A. PN Junction Diode

Sabse basic diode

Current sirf forward bias me flow karta hai

Use: Rectifier circuits

🧩 B. Zener Diode

Specially reverse bias me kaam karta hai

Voltage regulator circuits me use hota hai

🧩 C. Light Emitting Diode (LED)

Light produce karta hai jab current pass hota hai

Use: Indicator lights, displays, etc.

🧩 D. Schottky Diode

Fast switching ke liye use hota hai

Use: High speed circuits

🧩 E. Photo Diode

Light detect karta hai

Use: Light sensors, remote control receivers
