بخشي از مطالب اين مقاله ترانزيستور :

Transistor is one of the most widely used electronic devices in today's world. This electronic part is used as an electronic switch or as an amplifier in the electronics and communication industry, computers, mobile phones and other electronic devices. In this article, the characteristics, structure and applications of the transistor are investigated.

۱- تعریف ترانزیستور

A transistor is a temperature-sensitive electronic component that is made of a combination of three layers of different types. These three layers include one type of semiconductor (e.g. silicon) and two other types of semiconductors (e.g. P-type and N-type). Transistor, as an electronic device, is divided into two main types: Bi-junction Transistors (BJT) and Field Effect Transistors (FET).

۲- ساختار ترانزیستور

Bi-component transistors (BJT) consist of three main layers, two P-type and one N-type. The three layers used in BJT are: Emitter, Base and Collector. In BJT, current flows from emitter to collector and current control is done by base. In field-effect transistors (FETs), current flows from a positive semiconductor to a negative semiconductor. In this type of transistor, the current is controlled by the electric field created in the negative semiconductor.

۳- ویژگی‌های ترانزیستور

ویژگی‌های مهم ترانزیستور عبارتند از:

Amplification: Transistors can amplify current and voltage due to having one input and one output.

سرعت بالا: ترانزیستورها، سرعت بالایی در انتقال اطلاعات دارند.

Small size: New transistors are smaller in size and can be placed in a smaller space.

High efficiency: Transistors, with high efficiency, use less energy and heat up less.

پایداری حرارتی: ترانزیستورها، پایداری حرارتی بالایی دارند و در دماهای بالا همچنان کار می‌کنند.

The transistor was invented in 1947 at Bell Labs while researching better amplifiers and finding a better alternative to mechanical relays. Vacuum tubes had amplified sound and music in the first half of the 20th century, but they consumed a lot of power and quickly died. they burned Telephone networks also needed hundreds of thousands of mechanical relays to connect circuits to each other so that the network could stand on its feet, and because these relays were mechanical, they needed to be always clean for optimal performance. As a result, their maintenance and service is difficult and expensive. Was.
With the advent of the transistor, the prices were broken compared to the time of using the vacuum lamp and a great improvement was achieved in the quality of telephone networks.
