As the name suggests this resistor will daatasheet the current flowing through the transistor to prevent it from damaging. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

This transistor like all can be used either as a switch or as an amplifier. Submitted by webmaster on 11 December High frequency and microwave engineering. Other part numbers will have different parameters.

Commercial transistors Bipolar transistors.

Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. So if you looking for an NPN transistor that fatasheet switch loads of higher current then 2NA might the right choice for your project.

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. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds.

To make things simple I have shown a simplified circuit to make a transistor as switch. 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 BC is a low voltage, low current, general-purpose switching transistor in a TO package. The exact specifications depend on the manufacturer, case type, and variation.

This transistor will make it forward biased and thus closes the connection between collector and emitter. It is used in a variety of analog amplification and switching applications. 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.

In other projects Wikimedia Commons. The 2N, 2N, and datashret 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. Retrieved from ” https: However one important thing to notice is the Base resistor a.

The 2N is an NPN transistor that can only switch one-third the current of datashet 2N but has otherwise similar characteristics. Archived from the original on 14 April I have used a base voltage of 5V and a value of 1K as current limiting resistor.

dwtasheet Complete Technical Details can be found at the 2NA datasheet given at the end of this page. Wikimedia Commons has media related to 2N 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.

Retrieved 26 March This page was last edited on 25 Octoberat 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. 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.


Build your own low-power transmitters: 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. Junkbots, bugbots, and bots on wheels: 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.

Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. Learn to keep an eye open for the following transistors, ratasheet they’re among the most useful, inexpensive, and popular types: To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Note that the motor here draws about mA from the 12V power source, since the 2N has collector current rating upto mA this 22n22 is possible had it been a BC the transistor should have been burnt.

It was originally made in the TO metal can as shown in the picture. From Wikipedia, the free encyclopedia. Graf and William Sheets 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. In actual circuit modifications might be required.
