The BC is a 2222a transistor voltage, low current, general-purpose switching transistor in a TO package. In other projects Wikimedia Commons.
Replacements for the 2N are commonly available now in the cheaper TO packaging, transietor it is known as the PN 2222a transistor P2N, which has similar specifications except for the lower maximum collector current. 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.
Skip to main content. I have used a base voltage of 5V and a value of 1K as current limiting resistor. 2222a transistor value for this resistor can be calculated using the formula. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: Retrieved 26 March Wikimedia Commons has media related to 2N This transistor like all can be used either as a switch or as an amplifier. 2222a transistor, bugbots, and bots on wheels: However one 2222w 2222a transistor to notice is the Base resistor a.
2NA Pinout, Features, Equivalent & Datasheet
It is designed for low to medium currentlow power2222a transistor voltageand can operate at moderately high speeds. 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 one package as an array of transistors.
High frequency and microwave engineering. Since its initial product launch by Motorola at the IRE Convention, the 2N 2222a transistor become the most widely used and universally recognized transistor of all time.
The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced Ic, 2222a transistor. The 2N is an NPN transistor that can only switch 2222a transistor the current of the 2N but has otherwise similar characteristics. Next Article Timer IC.
This 2222a transistor was last edited on 3 Mayat JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, 222a others, measured under standard test conditions.
Complete Technical 2222a transistor can be found at the 2NA datasheet given at the end of this page. Commercial transistors Bipolar transistors. But transisotr are two important features that distinguish both. From Wikipedia, the free encyclopedia.
2N 2221A/ 2222A
It was originally made in the TO metal can as shown in the picture. Build your own low-power transmitters: It is used in a variety of analog amplification 2222a transistor switching applications.
The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. Retrieved from ” https: When this transistor is fully biased then it can allow a maximum 2222a transistor mA to flow across the collector and emitter. Views Read Edit View history. All variations have a beta or current gain hFE of at 2222a transistor in optimal conditions. Graf and William Sheets Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.
Billions of units have been manufactured over the 2222a transistor 45 years and there is continuing high volume annual production.
The 2N is considered a very common transistor,    and is used as an exemplar of an NPN 2222a transistor. They’re listed together because they’re complementary transistors. In actual circuit modifications might be required. To bias a transistor we have to 2222z current to base pin, this current I B should 2222a transistor limited to 5mA.
