A PN junction is one of the most important structures in semiconductor electronics. It forms the basic building block of many electronic devices such as diodes, transistors, LEDs, solar cells, rectifiers, and integrated circuits. When a P-type semiconductor and an N-type semiconductor are joined together without applying any external voltage, the junction is called an […]

Types of Diodes: Symbol, Working, Characteristics and Applications
Diode is a versatile electronic component, many specialized types of diodes exist, each optimized for specific applications such as voltage regulation, light emission, high-speed switching, and detection. It is one of the most fundamental semiconductor devices used in electronics. It plays a critical role in controlling the direction of current flow in a circuit. From […]
Why Different Types of Diodes Are Used in Modern Circuit Design?
If you’ve ever opened up an electronic device – anything from a laptop charger to a pair of gaming headphones – you’ll notice tiny components scattered across the board. Among them, the diode is one of the most essential. It doesn’t look like much, but it plays a massive role in how circuits behave and […]
Tunnel Diode Symbol, Construction, Working and Applications
The tunnel diode, also known as the Esaki diode, is a type of semiconductor diode that exhibits a unique behavior due to quantum mechanical tunneling. Leo Esaki invented the tunnel diode in 1957, and he received the Nobel Prize in Physics for it in 1973. Its negative resistance region in the current-voltage (I-V) characteristics makes […]
