What You Should Know About Transistors

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. From time to time, the transistors may blow and will have to be changed for your equipment to work. You will need to take the electronic item to a qualified technician to diagnose any problems it has as well as change any transistors, capacitors, diodes or other electronic components that may be faulty.

Transistors are small components that are used in the electric circuit boards of most electronic items. The components help to amplify signals by changing a small input signal to produce a large output. Transistors come in different voltages, amperes and wattage. Each transistor is given a part number. You can determine the performance and usage of a transistor based on its part number. Any blown transistors will have to be removed and replaced for your equipment to work. 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, the durability of a transistor is not determined by its wattage, amperes or voltage. A high specs transistor may be used on your gadget but blow up within a few weeks. You should check the manufacturer’s parts datasheet to know of the longevity of different transistors that can be used in your electronic equipment. The information on the datasheet will enable a technician know which transistor will last longer for your gadget. Like is expected, the longer a transistor will work, the more expensive it would be.

Manufacturing of Transistors
Every year, there are billions of transistors that are used in various circuit boards. These components are flexible, reliable and cheap to manufacture. This is why when the components malfunction, they are simply discarded and replaced. However, you will not find the billions of transistors manufactured being sold on the retail market. Instead, the major customers that buy the components are electronic equipment manufacturers. 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.

Majority of transistors are made of a semiconductor material such as silicon or germanium and have three layers. Impurities are added onto the layers to make them have either negative or positive electrical attributes. “P” and “N” are used to indicate a positively charged or negatively charged transistor layer respectively.
