The maximum amount of current that could flow through the Collector dataheet is mA, hence we cannot connect loads that consume more than mA using this transistor. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

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. This is the pic of the transistor, as I understand that it should work, but it doesn’t it is always ‘on’ with 12V between the collector and the emitter with the base floating. The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor.

Would you like to answer one of these unanswered questions instead? 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 Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

datasneet Archived dqtasheet the original on 14 April Typical examples are the 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.


The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. Retrieved 26 March Use dmy dates from July Commons category link datashee on Wikidata. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

The value for this resistor can be calculated using the formula. By using this site, you agree to the Terms of Use and Privacy Policy. Hence the 2N pin-out is sadly not standardized.

In other projects Wikimedia Commons. It was originally made in the TO metal can as shown in the picture. Javier Loureiro 1 7 However one important thing to notice is the Base resistor a.

Would I reuse it? 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. Wikimedia Commons has media related to 2N The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. This is the picture of the datasheet for the pins: The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.

I have a simple circuit to send current to a brushless fan running at 12V on datasehet high side, using a NPN transistor 2NA: Build your own low-power transmitters: Retrieved from ” https: The exact specifications depend on the manufacturer, case type, and variation. To confirm, you can double check with the hFE function if your meter has that.

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. To make things simple I have shown a simplified circuit to make a transistor as switch. Views Read Edit View history.

2NA Pinout, Features, Equivalent & Datasheet

All variations have a beta or current gain h fe of at least in optimal conditions. But there are two important features that distinguish both.

Commercial transistors Bipolar transistors. 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. 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.

The hFE is usually much higher when properly connected than when collector and emitter are 2222a. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same dztasheet The 2N exhibits its dtasheet gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. This page was last edited on 25 Octoberat If I set up the circuit datashete a quick test, it seems that the datasheet or the transistor has the pins swapped.

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

Therefore, it is important to refer to the datasheet for dataasheet exact part number and manufacturer.
