Can I use BC547 instead of BC337?
The BC547 transistors have such a wide range in current gain that BC337 transistors can replace them and some circuits will work well and others won’t, the same as if BC547 transistors were used. A TIP127 is a high voltage PNP power darlington transistor that is completely different from the NPN BC337 transistor.
What type of transistor is a BC337?
The BC337 is an NPN transistor with a maximum gain of 630, commonly used in low power audio applications. It can also switch loads upto 45V and 800mA hence also used as general purpose transistor.
How can check NPN and PNP transistor by multimeter?
Connect the positive lead of the multimeter to the Base (B) of the transistor and connect the negative lead to the Emitter (E) of the transistor. If it is an NPN transistor then meter should show a voltage drop between 0.45V and 0.9V. If it is a PNP transistor, then it should display see “OL” (Over Limit).
How does a bc337 transistor work?
This transistor works like a switch to convert the small current to a larger current at the transistor terminals. The base terminal is positive as compared to both the terminals like emitter & collector. As compared to the emitter terminal, the voltage at the collector terminal is positive always.
What is the use of BC547 transistor?
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.
Which transistor can be used in place of 2N2222A?
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.
How you can test a transistor?
Hook the positive lead from the multimeter to the to the EMITTER (E) of the transistor. Hook the negative meter lead to the BASE (B) of the transistor. For an good NPN transistor, you should see “OL” (Over Limit). If you are testing PNP transistor, the meter should show a voltage drop between 0.45V and 0.9V.
