If you have an electronic gadget such as a phone, computer or TV, you can be sure that it is using multiple transistors. You won’t hear of transistors a lot unless your TV screen needs to be repaired. Transistors are small components that are found in the circuit boards of most electronic gadgets. Sometimes, a power surge can make the transistors blow up and leave your equipment not functioning. 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.
All electronic equipment receive electronic signal through a motherboard or circuit board that is made up of transistors and other components such as diodes and capacitors. The components help to amplify signals by changing a small input signal to produce a large 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. Any blown transistors will have to be removed and replaced for your equipment to work. The transistors used for replacements must be of the same part number as the ones that are not working.
When replacing any transistors, the technician should opt for a longer lasting component. However, do not think that the ampere, voltage and wattage determines how long a transistor will last. A high specs transistor may be used on your gadget but blow up within a few weeks. To determine the longevity of a transistor, you have to check the information about it on the manufacturer’s datasheet. 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. Long-lasting transistors come at a higher price than the common transistors.
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 explains why when they blow, they are simply discarded rather than repaired. However, the billions of transistors that are manufactured are not sold to the end consumer. 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.
Transistors are manufactured to have three layers that are made of a semiconductor material such as silicon or germanium. The layers have either positive or negative electrical attributes based on the impurities that are added to them. A transistor layer that is marked “P” is positively charged while one that is marked “N” is negatively charged.
