Can a NPN transistor be used as a substitute for a 2n in a flyback driver circuit? Thread starter Rahulk70 Start date Apr 23, Search Forums New Posts. Thread Starter Rahulk70 Joined Dec 16, Hi everyone, I'm trying to build a flyback driver circuit.
I saw a few online videos and circuits where people where using 2N driver circuits. Can I just substitute the 2N with or the 2N transistors? Scroll to continue with content. DickCappels Joined Aug 21, 6, Note that the circuit with two transistors is not a flyback converter, so you would need a lot more turns on the secondary if everything else were similar. Yes, you can use the SBP The 2N is not really very good at high frequency switching, so not having any is not a disadvantage.
The SBP on the other hand is a very nice switching transistor that can withstand a collector voltage 10X that of the 2N The 2N is a Darllington and not well suited to your application. The SBP is the best of the three. The single transistor circuit a good candidate but there is no obvious way to limit the collector voltage.
Do you want to make this for a particular application or do you just want to make a high voltage? So, I guess I'm good to go with the transistor. Not for any particular application right now, just wanted to make a high voltage supply those with arcs.
I have a dozen ICs with me thought of doing it initially but just wanted to go with a simple transistor driver first then with the Dodgydave Joined Jun 22, 8, Last edited: Apr 23, The has a 7A current rating whereas the 2n rating is 15A.

So you can also recycle old Electronics. The Transistor's Base takes the low audio signal and then amplifies the signal. To a Higher amplitude.
Higher amplitude means High Volume. Here I have used a uf Capacitor for absorbing the Higher Frequencies. Now the transistor will give a great result. Here I used 1k Resistor for removing lower Frequencies. This will increase the sound quality of the speaker. When the Base of the transistors gets to the low amplitude signal then the base became active in this state.
For this reason, the Transistor became a conductive Collector to Emitter. In this way, the Speaker Runs. So, this is a Simple amplifier circuit made up of Transistors. The audio quality is really loud from the amplifier. It is just a 3 component amplifier. If you have some old power Supply then you can get all the components easily there. The construction is pretty much simple.

Thank you to our community and to all of our readers who are working to aid others in this time of crisis, and to all of those who are making personal sacrifices for the good of their communities. We will get through this together. Updated: July 29, Reader-Approved References. A transistor is a semiconductor that allows current to flow through it under certain conditions, and cuts current off when other conditions are present.
Transistors are commonly used as either a switch or a current amplifier.
You can test a transistor with a multimeter that has a diode test function. Then, touch the red probe to the emitter and read the display to see if the resistance is high or low. Next, move the red probe to the collector, and check that the reading is the same as it was before.
Once you have those readings, remove the black probe from your transistor and clamp the red probe to the base. You can then touch the black probe to the emitter and collector and look at the new readings. Your transistor is good if your previous readings were both high and the current readings are both low, or the opposite is true.

Learn moreThis form of testing is able to detect whether transistor or a diode is operational, and although it cannot provide details of the parameters, this is seldom a problem because these components will have been tested at manufacture and it is comparatively rare for the performance to fall to a point where they do not operate in a circuit.
Most failures are catastrophic, rendering the component completely inoperable. These simple multimeter tests are able to detect these problems very quickly and easily. The basic diode test is very simple to perform. Just two tests are needed with the multimeter to ensure that the diode works satisfactorily.
The diode test relies on the fact that the diode will only conduct in one direction and not the other. This means that its resistance will be different in one direction to that of the other. By measuring the resistance in both directions, it is possible to ascertain whether the diode is working, and also which connections are the anode and cathode. As the actual resistance int he forward direction is dependent upon the voltage, it is not possible to give exact values for the expected forward resistance as the voltage from different meters will be different - it will even be different between different ranges on the meter.
Notes: In step 3 above the actual reading will depend upon a number of factors. The main thing is that the meter deflects, possibly to half way or more.
The variation depends on many items including the battery in the meter, and the range used. The main point to note is that the meter deflects significantly. When checked in the reverse direction, silicon diodes are unlikely to show any meter deflection whatsoever. Germanium ones that have a much higher level of reverse leakage current may easily show a small deflection if the meter is set to a high ohms range. This simple analogue multimeter test of a diode is very useful because it gives a very quick indication of whether the diode is basically operational.
It cannot, however, test more complicated parameters such as the reverse breakdown, etc. Nevertheless it is an essential test for maintenance and repair. Although it is possible for the diode characteristics to change, this very rarely happens and it is far ore likely that a complete breakdown of the diode occurs, and this would be immediately visible using this test. Accordingly this type of test is exceedingly useful in a number of areas of electronics test and repair.
The diode test using an analogue multimeter can be extended to give a simple and straightforward confidence check for bipolar transistors. Again the test using a multimeter only provides a confidence check that the bipolar transistor has not blown, but it is still very useful. As with the diode, the most likely failures result in the destruction of the transistor, rather than a slight degradation in the performance.
The test relies on the fact that a bipolar transistor can be considered to comprise of two back to back diodes, and by performing the diode test between the base and collector and the base and emitter of the transistor using an analogue multimeter, most of the basic integrity of the transistor can be ascertained. One further test is required. The transistor should present a high resistance between the collector and emitter with the base left open circuit as there are two back to back diodes.
However it is possible for the collector emitter path to be blown and a conduction path created between the collector and the emitter whilst still having a diode function to the base.
This also needs to be tested. It should be noted that a bipolar transistor cannot be functionally replicated using two separate diodes because the operation of the transistor depends upon the base which is the junction of the two diodes, being one physical layer, and also very thin. The instructions are given primarily for an NPN transistor as these are the most common types in use. The variations are shown for PNP varieties - these are indicated in brackets. Notes: The final checks from collector to emitter ensure that the base has not been "blown through".
It is sometimes possible that there is still a diode present between collector and base and the emitter and the base, but the collector and emitter are shorted together.Today in this article we are going to discuss How to Make a High Power amplifier circuit with Transistor.
You can find all the components from old damaged Power supplies. So you can also recycle old Electronics.

Now take a uF Capacitor. And now connect it with the transistor. With the circuit. The 3. You can also directly connect the audio signal to the circuit. But for my case, I am using my Phone for the audio signal output.
