SOME EXAMPLE DIODE CIRCUITS

3. WHAT’S A DIODE
The diode is a passive electronic component non-linear,two-terminal (bipolar), that allows the flow of electric current only in one direction.

4. For these proprieties the diodes is called rectifier

5. A diode’s I–V characteristic can be approximated by four regions of operation (see the next figure).

9. TYPES OF DIODES
THERE ARE MANY DIODES:
ZENER
SCHOTTKY
VARICAP
LED

10. Zener diodes
Diodes that can be made to conduct backwards. This effect, called Zener breakdown, occurs at a precisely defined voltage, allowing the diode to be used as a precision voltage reference

11. LED A light-emitting diode (LED)is an electronic light source.
LEDs are based on the semiconductor diode.
