To use Bjt as an amplifier, emitter-base junction is forward biased whereas the collector-base junction is reverse biased. When the input voltage is applied at emitter and base terminal, some amount of current starts to flow from base to the emitter which controls the current at the collector terminal. The inputted signal is amplified at the base and then gets transferred to the emitter. It is best operated in the active region.īC547 is biased in such a way that it is partially on for all the applied inputs. For proper operation of the transistor, A fixed DC voltage is required. Supplying a proper DC voltage to the transistor is known as the biasing of transistor. The maximum current gain of this transistor is around 800. The current flowing from base to the emitter controls the current flowing through the collector.īC547 is usually used for amplification and switching purposes. In transistors, a small amount of current at the base terminal controls a larger amount of current at the emitter and collector.īC547 has three terminals as in other transistors. The use of a transistor is to transfer the resistance. The word transistor means of two words, transfer and resistor. It is widely used for power amplification and switching. Bc-547 is an NPN bipolar junction transistor(BJT). Do not use the device at an over temperature of more than 150c.Here are the Top 5 DIY bc547 transistor project for you. Do not drive the device above 30V, and always use the pins with the correct direction because wrong input can damage the transistor. To increase the performance of this transistor you should, must follow the guidelines and specifications given above in technical specifications. Darlington pair can be made with this also.Amplifier modules like Audio amplifiers, signal Amplifiers, etc.Driver Modules like Relay Driver, LED driver, and switching modules.PNP Complementary of BC548 are BC556, BC557, and BC558. Max Storage & Operating temperature Should Be: -55 to +150CīC547, 2N2222, BC549, BC550,2N3904,3906 are the alternate of BC548 but pin configurations may differ so, must check the pin configuration before the use of any alternate of BC548.BC548 current gain value is from 110 to 800, BC548A is from 110 to 220, BC548B is from 200 to 450 and BC548C is from 420 to 800. The Difference among the four is only their DC current gain value.
