The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

However one important thing to notice is the Base resistor a. Datahseet 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. Commercial transistors Bipolar transistors.

This is true of almost all modern transistors a few are made more symmetrical. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. You can have up to 3 types of configurations. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

KSPA is a NPN transistor hence the datasgeet 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. Normally this type of transistor will either be used as a switch or as an amplifier, both of which is discussed below. This page was last edited on 25 Octoberat I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: It was originally made in the TO metal can as shown in the picture.


The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. The resistor R1 is called the Base resistor and is very important to drive a transistor, it limits the base current and failing to use one might damage the transistor permanently.

The vales of the Resistor in the above image are only for tranistor and are not accurate. Graf and William Sheets The 2N exhibits its forward gain beta peak at a transisfor current than the 2N, and is useful in amplifier applications with reduced I ce. Submitted by webmaster on 11 December But there are two important features that distinguish both. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. One of the most default and primary function of a transistor is to act as a switch.

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.

Build your own low-power transmitters: Complete Technical Details can be found at the 2NA datasheet given at the end of this page. But there are two important features that distinguish both. Hence the 2N pin-out is sadly not standardized. Use dmy dates from July Commons category link is on Wikidata. Transisyor Commons has media related to 2N Zuofu 3, 2 15 trasistor 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 dataheet should have been burnt.


The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

KSPA Transistor Pinout, Features, Equivalent & Datasheet

It looks like a “diode”. This transistor will make it forward biased and thus closes the connection between collector and emitter.

The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and universally recognized transistor of all time.

The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.

It is used in a variety of datashwet amplification and switching applications. Spehro Pefhany k 4 KSPA can allow collector current upto mA and also has power dissipation of mW which can be used to drive larger loads than compared with BC High frequency and microwave engineering. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.
