Use dmy dates from July Commons category link is on Wikidata. Hence the 2N pin-out is sadly not standardized. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. 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.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. I am trying to figure out what is going on here.

ST Microelectronics – datasheet pdf

Commercial transistors Bipolar transistors. It is used in a variety of analog amplification and switching applications.

The base will show a diode connection to both other pins, in only one polarity. No other pin will show that. Single transistors are also available in several different surface mount packages, and a datasheft of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.


Javier Loureiro 1 7 This is true of almost all modern transistors a few are made more symmetrical. It looks like a “diode”. This is the picture of the datasheet for the pins: As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. You can have up to 3 types of configurations.

Junkbots, bugbots, and bots on wheels: The BC is a low voltage, low current, general-purpose switching transistor in a TO package.

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 exact specifications depend on the manufacturer, case type, and variation. Other part numbers will have different parameters.

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. When I apply a voltage between the pin dqtasheet to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot.

In actual circuit modifications might be required. But there are two important features that distinguish both. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.


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 transistor like all can be used either as a switch or as an amplifier.

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. Views Read Edit View history. Would you like to answer one of these unanswered questions instead?

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. Thank you for your interest in this question.
