Difference between LED and PN junction diode

LED PN junction diode The LED emits light. The PN junction diode cannot emit light. The LED uses GaAs, GaAsP or GaP material. The PN junction diode silicon or germanium material. In LED all energy converted into

Applications of point contact diode

The point contact diodes are certainly continued to be of great importance of some time to come. Some of their characteristics are very desirable for certain applications. There are some important applications of point contact diode which

How infra red light emitting diode (IR LED) works?

The infra red light emitting diode (IR LED) is a gallium arsenide PN junction diode which emits a beam of radiant flux when forward biased. The infra red LED is also known as IR transmitter. It is
