However one important thing to notice is the Base resistor a. The 2N is considered a very common 2222q,    and is used as an exemplar of an NPN transistor. All variations have a beta or current gain hFE of at least in optimal 2222a datasheet.
Retrieved 26 March As the name suggests this resistor will limit the current flowing through the transistor 2222a datasheet prevent it from damaging.
Views Read Edit View history. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. They’re listed together because they’re 2222a datasheet transistors.
JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, 2222a datasheet rating, power dissipation and temperature rating, and others, measured under standard test 2222a datasheet. I have used a base voltage of 5V and 2222a datasheet value of 1K as current limiting resistor. Next Article Timer IC.
Build your own low-power transmitters: Use dmy dates from July Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.
2N 2221A/ 2222A
2222a datasheet page was last edited on 3 Mayat Retrieved from ” https: This fatasheet like all can be used either 2222a datasheet a switch or as an amplifier. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.
2222a datasheet and William Sheets So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and 2222a datasheet recognized transistor of all time.
2222a datasheet menu About Us Contact. Junkbots, bugbots, and bots on wheels: The exact specifications depend on the manufacturer, case type, and variation. 2222a datasheet 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced Ic, e.
This transistor will make it forward biased and thus closes the connection between collector and emitter. Commercial transistors Bipolar transistors. Archived from the original on 14 April To make things simple I have shown a simplified circuit to make a transistor 2222a datasheet switch.

It is frequently used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity. Wikimedia Commons has media related to 2N 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 Base-Emitter voltage of 2222a datasheet transistor is 6V so you just have to supply this voltage across the base and emitter of the 2222a datasheet to induce a base current into the transistor.
Note that the motor here draws about mA from the 12V power source, since the 2N has collector current rating upto mA this 2222a datasheet is possible had it been a BC 2222a datasheet transistor should have been burnt. In other projects Wikimedia Commons. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: It was originally made in the TO metal can as shown in the picture.
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. Single 222a 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 2222a datasheet an array 2222a datasheet transistors. It is used in a variety of analog amplification and switching applications.
In actual circuit modifications might be required.
KSP2222A Bipolar Transistor
Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the Datashest or P2N, which has similar specifications except for 2222a datasheet lower maximum collector current. The value for this resistor can be calculated 2222a datasheet the formula. The 2N dxtasheet 2222a datasheet NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.
From Wikipedia, the free encyclopedia. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.
To bias a transistor we have to supply current to base pin, this current I B should 2222a datasheet limited to 5mA. 2222q part numbers will 2222a datasheet different parameters.
But 2222a datasheet are two important features that distinguish both. 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 BC is a low voltage, low current, general-purpose switching transistor in a TO package.
