How Do Transistors Work?

TVs, computer screens, phones, electric cookers, and nearly all other electronic gadgets rely on transistors to function properly. Unless you are an electrical technician or are interested in electronics, chances are that you do not know what transistors are. Transistors are part of the small components that work together in a mother board or electronic circuit used in electronic equipment. Sometimes, a power surge can make the transistors blow up and leave your equipment not functioning. When your equipment malfunctions due to a burned transistor, you will need to take it to a qualified technician for repairs.

Transistors are small components that are used in the electric circuit boards of most electronic items. The work of transistors is to increase a small input electronic signal to a high output. Electronic gadgets use transistors of different wattages, amperes and voltages. Each transistor is given a part number. The part numbers indicate the performance and usage of the components. If your TV screen is not functioning because of a blown transistor, you will need the component replaced. The technician will have to use the same part number transistor to replace the malfunctioning component.

It is important for technicians to use long-lasting transistors when repairing your gadgets. However, do not think that the ampere, voltage and wattage determines how long a transistor will last. A transistor may have a higher specification but may blow up the first time you switch on your gadget. You should check the manufacturer’s parts datasheet to know of the longevity of different transistors that can be used in your electronic equipment. In the datasheet, a technician can read the lifespan of different transistors that can work for your gadget and suggest the best one to use for replacement. You should expect to pay more for a long-lasting transistor.

Manufacturing of Transistors
Every year, there are billions of transistors that are used in various circuit boards. The flexible electronic components are not expensive to manufacture. This explains why when they blow, they are simply discarded rather than repaired. However, the majority of the components are not put on the market for sale. Electronic equipment manufacturers purchase the bulk of the billions of transistors to use them in their circuit boards. The transistors are so small that hundreds of thousands of them may be used on a single circuit board. The components are important components in a circuit board and work with diodes and capacitors to ensure proper flow or current.

All transistors have three layers that are usually made of a germanium semiconductor material. Impurities are added onto the layers to make them have either negative or positive electrical attributes. A transistor layer that is marked “P” is positively charged while one that is marked “N” is negatively charged.
