It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds.
This transistor like all can be used either as a switch or as an amplifier. They’re listed together because they’re complementary transistors.
The exact specifications depend on the manufacturer, case type, and variation. But there are two important features that distinguish both. Retrieved 26 March In actual circuit modifications might be required. In other projects Wikimedia Commons. However one important thing to notice is the Base resistor a. Wikimedia Commons has media related to 2N From Wikipedia, the free encyclopedia. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and datwsheet rating, and others, measured under standard test conditions.
When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. The value for this resistor can be calculated using the formula. Since its initial product launch by Motorola at the IRE Convention, the 2N has datashdet the most widely used and universally recognized transistor of all time.
It is used in a variety of analog datwsheet and switching applications. To bias a transistor we have to supply current to base pin, this current I B should be datzsheet to 5mA. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.
The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. This page was last edited on 25 Octoberat Typical examples are the well known NPN dataseet PNP industrial and military types, 2N and 2N, which have been used for over four decades and are still being used in many designs.
Therefore, it is important eatasheet refer to the datasheet for the exact part number and manufacturer. Junkbots, bugbots, and bots on wheels: Views Read Edit View history. Submitted by webmaster on 11 December It is frequently datasehet as a small-signal transistor,   and it remains a datasheer general purpose transistor  of enduring popularity.
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 are similar, with the biggest difference being the maximum allowable current and power dissipation. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.
All variations have a beta or current gain 2n2222 fe of at least in optimal conditions. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. Archived from the original on 14 April TL — Programmable Reference Voltage.

Replacements for the 2N are commonly available now in the cheaper TO xatasheet, where it is known as the PN or P2N, which has similar specifications except for the lower maximum collector current. Build your own low-power transmitters: 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.
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.
It was originally made in the TO metal can as shown in the picture. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: This transistor will make it forward biased and thus closes the connection between collector and emitter. Graf and William Sheets The maximum amount of current that could flow through the Collector pin is mA, hence we cannot dafasheet loads that consume more than mA using this transistor.
When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.
