What is the use of BC558 transistor?

BC558 is a bipolar junction transistor used for amplification and switching purposes. It belongs to the PNP transistor family and is available in a TO-92 package. It contains collector current 100mA, indicating it can drive load under 100mA.

How does the BC557 transistor work?

BC557 is a bipolar junction transistor that falls under the family of PNP transistors. And when voltage is applied at the base terminal, the transistor is turned OFF and both emitter and collector will be reverse biased.

What is difference between BC547 and BC557?

BC557 is PNP, BC547 is NPN to see what is this transistor reconstruct circuit from existing PCB on paper, then you will know.

What are the functions of the emitter base and collector regions in a transistor?

The base is the gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply. By sending varying levels of current from the base, the amount of current flowing through the gate from the collector may be regulated.

How does BC547 transistor work?

The BC547 transistor is an NPN transistor. A small current of the base terminal of this transistor will control the large current of emitter and base terminals. The main function of this transistor is to amplify as well as switching purposes. The maximum gain current of this transistor is 800A.

Which transistor can be used in place of BC547?

BC547 Transistor Equivalent BC547 transistor can be used as an alternative to many transistors: BC548, BC549, BC636, BC639, 2N2222 TO-92, 2N2222 TO-18, 2N2369, 2N3055 and 2N3904 all are BC547 transistor equivalent.

Why BC547 transistor is used?

BC547 Transistor Application BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.

What is the use of BC548 transistor?

BC548 transistor is used for amplifying and switching purposes in electrical circuits. Like every other NPN transistor, it consists of three pins: the collector, base, and emitter.
