Usually a 2N will suffice for most circuits, but if you need more than mA, then you should use a 2N instead.

2N transistor datasheet & applicatoin notes – Datasheet Archive

The exact performance characteristics depend on the manufacturer and date; before the move to the epitaxial base version in the mids the f T could be as low as 0. RCA by had changed their specification to give 2.


The maximum collector-to-emitter voltage for the 2N, like other transistors, depends on the resistance path the external circuit provides between the base and emitter of the transistor; with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.

Sometimes the V CBO breakdown voltage the maximum voltage between collector and base, with the emitter open, an unrealistic arrangement in practical circuits is given hransistor the only voltage rating, which can cause confusion. If you need greater than mA but less than 1A, then the 2N will be the one to use.


2N / BC / PN / 2N NPN Transistor – NTEAP

It is designed for low current and powermedium voltageand can operate at moderately high speeds. It has a transition frequency of 2. By using this site, you agree to the Terms of Use and Privacy Policy.

In case you’re curious about which to use, or which one is better or superior than the other, in this article, we compare and contrast the 2 transistors. It was produced exclusively by the Czechoslovakian electronics company Tesla.

Typical components that may require a transistor in order to be driven are motors, buzzers, solenoids, and high-power LEDs. The 2N is a silicon NPN power transistor intended for general purpose datashheet. These really dagasheet extreme conditions. Variants with higher voltage ratings e. The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N In simplicity, this really means that 40V is the maximum amount of voltage that the transistor can tolerate minus the voltage drop across the load connected to the collector.

Wikimedia Commons has media related to 2N KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor.

The 2N remains very popular as a series pass transistor in linear power supplies and is still used in for medium- current and high- power circuits generally, including low frequency power converters although its use in audio power amplifiers and DC-to-AC inverters is now less common and its use in higher frequency transisgor applications never was very practical.


However, it doesn’t necessarily mean it’s the transistor that you should use. Transistor Man looks at the current going from the base to the emitter. The total power dissipation written P D in most American datasheets, P tot in European ones depends on the heatsink to which the 2N is connected. So the choice ultimately depends datasehet how much current is needed.

2N3904 vs 2N2222

This means that in a circuit, voltage and current are biased to them the same exact way- they both must receive positive voltage to the base and collector terminals in order to operate. The robot builder’s bonanza 2nd ed. Dqtasheet these ways, the 2N and the 2N are both identical.

Retrieved from ” https: Views Read Edit View history. A 2N can handle up to 5 times that amount, since it can handle up to 1A ampere of current flow from the emitter to collector to power on a load. Retrieved from ” https: This page was last edited on 22 Novemberat It is by now unlikely to actually obtain a genuine 2N transistor when using popular sales platforms such as Amazon or Ebay; classic electronics distributors are mostly still able to properly source them.

The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. When figuring out DC current gain, the beta value is part of the formula.
