To make things simple I have shown a simplified circuit to make a transistor as switch. 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. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more datashet mA using this transistor.
How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The exact specifications depend on the manufacturer, case type, and variation. Most 2Ns have the orientation which your diagram shows, where 2222z the flat side is facing you, the pins are E-B-C respectively.
I have used a base voltage of 5V and a value of 1K as current limiting trznsistor. High frequency and microwave engineering. There are many types of amplifier transistof that are possible with transistor but this is the most commonly used one because it is very good in amplifying low frequency voltage signals like audio signals.
The capacitors C1 and C2 are simply used for filtering purpose.
KSPA Transistor Pinout, Features, Equivalent & Datasheet
Retrieved 26 March I don’t think so – throw it in the bin. No other pin will show that. This page was last edited on 25 Octoberat To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.
Spehro Pefhany k 4 Views Read Edit View history. The hFE is usually much higher when properly connected than when collector and emitter are swapped.
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 can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: In other projects Wikimedia Commons. The value for this resistor can be datashdet using the formula. 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,   and it remains a small general purpose transistor  of enduring popularity. But there are two important features that distinguish both.
I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: Normally this type of transistor will either be used as a switch or as an amplifier, both of which is discussed below. So if you looking for an NPN 222a2 that could switch loads of higher current then 2NA might the right choice for your project. Commercial transistors Bipolar transistors. Every transistor has a gain h FE associated with it, which can be used to amplify voltage or current.
Would I reuse it? However this type of amplifiers have many drawback and if you are looking for some serious amplification applications then you should look into Op-Amps which are nothing but a package of many transistors put to gather with amplification as its sole purpose.
ST Microelectronics – datasheet pdf
It is used in a variety of analog amplification and switching applications. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. Use dmy dates from July Commons category link is on Wikidata.
They’re listed together because they’re complementary transistors. Zuofu 3, 2 15 Would you like to answer one of these unanswered questions instead? Submitted by admin on 24 June The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. If it is to datxsheet a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N Javier Loureiro tfansistor 7 Typical examples are the well trasistor 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.
JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions. It is very similar to a mechanical switch but here we will control the switch using electric signals.

It was originally made in the TO metal can as shown in the picture. The vales of the Resistor in the above image are only for reference and are not accurate.
All variations have a beta or current gain h fe of at least in optimal conditions. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.
