What does B indicate in transistor BC547?
These are named as the emitter (E), collector(C) and base (B).
Is BC547 NPN or PNP?
NPN transistor
BC547 -> BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. BC547 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
Which transistor is equivalent of 2N2222?
The 2N2907 is an equally popular PNP transistor complementary to the 2N2222. The 2N3904 is an NPN transistor that can only switch one-third the current of the 2N2222 but has otherwise similar characteristics.
Which transistor can be used in place of BC548?
BC548 Equivalents
BC548 can be replaced by BC547, BC549, 2N2222, 2N3904, and BC550, though the pin configuration of some transistors may be different from BC548, so please check the pin configuration first before replacing in a circuit.
What is the difference between 2N3904 and 2N2222?
2N3904 can handle up to 200mA (milliamperes) of current flowing from the emitter to the collector terminal. A 2N2222 can handle up to 5 times that amount of current, as it can handle up to 1A (amps) of current flow from emitter to collector to power a load.
How does the transistor work?
A transistor consists of two PN diodes connected back to back. It has three terminals namely emitter, base and collector. The basic idea behind a transistor is that it lets you control the flow of current through one channel by varying the intensity of a much smaller current that’s flowing through a second channel.
What does C indicate in transistor BC548?
In the BC548 and BC547 transistors, the name B letter indicates that silicon material is used to build the transistor and the C letter indicates that, it is a transistor that handles low power audio frequency. They both are NPN transistors which are known as through-hole type and (TO-92 package) externally.
Why BC547 transistor is used?
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 difference between 2N2222 and 2N2222A?
What are 2N2222 and 2N2222A Transistors? Both transistors are from the same family but the 2N2222A has higher Maximum absolute ratings than 2N2222. The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of 2N2222 and 2N2222A are 60V, 30V, 5V, and 75V, 40V, 6V respectively.
How many watts can a 2N2222 handle?
It’s a current controlled transistor. It has a Collector current of 800 mA. Power Dissipation of 2N2222 is 500mW. It can operate between -65 C to 200 C temperature.
What is BC548 transistor?
BC548 is a NPN transistor so the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. BC548 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
Can I use 2N2222 instead of 2N3904?
The 2N3904 or 2N2222 will suffice if you require less than 200mA. The 2N2222 is the one to choose if you require more than 200mA but not more than 1A. For most circuits, a 2N3904 would suffice, however, if you need more above 200mA, a 2N2222 should be used instead.
How much current can a 2N2222 handle?
Why is transistor used?
A transistor can act as a switch or gate for electronic signals, opening and closing an electronic gate many times per second. It ensures the circuit is on if the current is flowing and switched off if it isn’t. Transistors are used in complex switching circuits that comprise all modern telecommunications systems.
