I don’t think so – throw it in the bin.

So if you looking for an NPN transistor that could switch loads of higher current then KSPA might the right choice for your project. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.
The Base-Emitter voltage of this transistor is 6V so you just have to supply this 2222 across the base and emitter of the transistor to induce a base current into the transistor. The general specifications of the datxsheet variants are similar, with the biggest difference being the maximum allowable current and power dissipation. The 2N is considered a very common transistor,    and is used as an exemplar of an NPN transistor.
But there are two important features that distinguish both. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count.
It was originally made in the TO metal can as shown in the picture. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.
Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.
Other part numbers will have different parameters. The exact specifications depend on the manufacturer, case type, and variation.
Complete Technical Details can be found at the 2NA datasheet given at the end of this page. Spehro Pefhany k 4 When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.
To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. TL — Programmable Reference Voltage. Note that the motor here draws about mA from the 12V power source, since the 2N has collector current rating upto mA this circuit is possible had it been a BC the transistor should have been burnt.
This transistor will make it forward biased and thus closes the connection between collector and emitter. Retrieved from ” https: It is used in a variety of analog amplification and switching applications.
Retrieved 26 March They’re listed together because they’re complementary transistors. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.
When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage datashset be around mV. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.
It is frequently used as a datasehet transistor,   and it remains a small general purpose transistor  of enduring popularity. Applications General purpose NPN transistor Can be used to switch high current upto mA loads It can also be used in the various switching applications. Transistor as Amplifier Another Common application of a Transistor is daasheet amplifiers.
I am trying to figure out what is going on here. To make things simple I have shown a simplified circuit to make a transistor as switch.
2NA Pinout, Features, Equivalent & Datasheet
All variations have a beta or current gain h fe of at least in optimal conditions. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.
Submitted by admin on 24 June If it is to replace a shorted transistor, we will never know if both daatsheet the same ebc configuration between your new 2N and the old 2N One of the most default and primary function of a transistor is to act as a switch. Would I reuse it?
