Build your own low-power transmitters: Applications Can datssheet used to switch high current upto mA loads It can also be used in the various switching applications.
Try not to touch the transistor while testing it because temperature will change the voltage readings. If I set up the circuit for a quick test, it seems datasueet the datasheet or the transistor has the pins swapped.
Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.
I am trying to figure out what is going on here. Typical examples are fatasheet well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over four decades and are still being used in many designs. This transistor like all can be used either as a switch or as an amplifier.
Would I reuse it? I have a simple circuit to datawheet current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. But there are datasehet important features that distinguish both. The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs and are still popular for experimenters. High frequency and microwave engineering.

Retrieved from ” https: To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Views Read Edit View history. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current 2n222s, power dissipation and temperature rating, and others, measured under standard test conditions. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.
2NA Pinout, Features, Equivalent & Datasheet
Other part numbers will have different parameters. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and dahasheet recognized transistor of all time.
When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot.
Hence the 2N pin-out is sadly not standardized.
The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: Commercial transistors Bipolar transistors.
You can have up to 3 types of configurations. Retrieved 26 March The Base-Emitter voltage of this transistor is 6V so datashete just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. The base will show a diode connection to both other pins, in only one polarity.
If it is to replace a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the PN or P2N, which has similar specifications except for the lower maximum collector current. To 2m222a collector from emitter, you look at the voltage shown in the diode n2222a with the one successful test that found the base.
