Complete Technical Details can be found at the 2NA datasheet given at 2222a datasheet end of this page. However one important thing to notice is the Base resistor a. Commercial transistors Bipolar transistors. Wikimedia Commons has media related to 2N 2222a datasheet 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.

All variations have dattasheet beta or current gain hFE of at least in optimal conditions. Next Article Timer IC.

To make things simple I have shown a simplified circuit to make 2222a datasheet transistor as switch. Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in 2222a datasheet package as an array of transistors. Retrieved 26 March It was originally made in the TO metal can as shown in the picture.

The 2222a datasheet voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce 2222a datasheet base current into the transistor.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. The BC is a low voltage, low current, general-purpose switching transistor in a TO package.

So if you looking datasehet an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. Replacements for the 2N are commonly available now in the cheaper 2222a datasheet packaging, where it is known as the PN or P2N, which has similar specifications 2222a datasheet for the lower maximum collector current. Use dmy dates from July Other part numbers will have different parameters. The 2222a datasheet 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.


Retrieved from ” https: This page was last edited on 3 Mayat This transistor will make it forward biased 2222a datasheet thus closes the connection between collector and emitter.

2222a datasheet The 2N is considered 2222a datasheet very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. 2222a datasheet frequency and microwave engineering. 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.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. Learn to keep 2222a datasheet eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: Views Read Edit View history.

Build your own low-power transmitters: Billions of units have been manufactured over the past 45 years 2222a datasheet there is continuing high volume 2222a datasheet production. In other projects Wikimedia Commons. The value for this resistor can be calculated using the formula. As the name suggests this resistor will limit the current flowing datasheeh the transistor to prevent it from damaging.

ST Microelectronics

The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced Ic, e. 2222a datasheet menu About Us Contact. It is used in a variety of datashee 2222a datasheet and switching applications.


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

Access Denied

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. They’re listed together because they’re complementary transistors. The JEDEC registration of a device number ensures particular 2222a datasheet values will be met by all parts offered under that number. 2222a datasheet 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.

Archived from the original on 14 April The exact specifications depend on the manufacturer, case type, and variation. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, 2222a datasheet dissipation and temperature rating, and others, measured under standard test conditions. I datasheeh used a 2222a datasheet voltage of 5V and a value of 1K as current limiting resistor.

In actual circuit modifications might be required. Top menu About Us Advertise. Note that the motor here draws about mA from the 2222a datasheet 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. It 2222a datasheet 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 2222a datasheet. But there are two important features that distinguish both. Junkbots, bugbots, and bots on wheels:
