Chinas semiconductor industry is growing at double-digit rates. According to a survey conducted by the research institutes, with the lead of the Internet of Things, AI, 5G and cInternet of Vehicles, the output value of semiconductors in China will reach 5,176 billion yuan in 2017, an annual increase rate of 19.39%. It is estimated that in 2018, it is expected to challenge a record high of 620 billion yuan, maintaining the annual growth rate of 20%, higher than the global semiconductor industry growth rate of 3.4% in 2018.

Laser diode: This type of diode is not the same as the ordinary light emitting diode because it produces coherent light. Laser diodes are widely used in many applications from DVD and CD drives to laser light pointers for presentations. Although laser diodes are much cheaper than other forms of laser generator, they are considerably more expensive than LEDs. They also have a limited life.

Rectifier diodes are electronic devices that allow electrical current to flow in one direction only. Because of this electrical property, diodes are used to convert alternating current electrical energy into direct current electrical energy. In an automotive electrical system, diodes can be found in several places, including the alternator. Alternator diodes perform three critical functions for the automotive charging system.

Voltage regulator is a device which provides a constant and regulated voltage at the output, irrespective of the variations in the supply voltage. Zener diode is used as a regulator in the electronics circuits in reverse voltage. Its this property to regulate voltage is due to its characterstics.

We know that small signal diodes are used in several applications like current steering, over voltage protection, switching circuits, clipping circuits, clamping circuits, snubbing the small duration waveforms and the most important of all: power conversions (from AC to DC). Small signal diodes conduct current solely in one direction: from anode to cathode and this is the most important property used in converting alternating current to direct current. This process of current conversion is called as Rectification and the circuits used are called Rectifiers.

Structurally, rectifiers can take a multiple forms, which include olden day’s vacuum tube diodes, copper and other metal oxide rectifiers and mercury arc valves. With the introduction of semiconductor electronics in recent days, rectifiers are mostly constructed from semiconductor diodes, thyristors or silicon controlled rectifiers (SCRs) (a type of thyrister) and other silicon based semiconductor switches.

There are two types of semiconductor components in electronic and electrical circuits. They are active and passive components. Diodes are the foremost active components and resistors are the foremost passive components in electronic design circuits. Diodes are essentially unidirectional devices having exponential relationship for the current-voltage characteristics are made from semiconductor materials.

Transistor is symmetrical to a vacuum triode and relatively very small in size. Transistor is a composition of two words Transfer and Varistor. A transistor consists of three layers of semi conductor material and each layer is having the capability of transferring current to the other layers.
