ST Microelectronics – datasheet pdf

From Wikipedia, the free encyclopedia. Therefore, it is important to refer to 2222a datasheet datasheet for the exact part number and manufacturer. The 2N exhibits its forward 2222a datasheet beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced Ic, e. The Base-Emitter 2222a datasheet of this transistor is 6V so you just have datadheet 2222a datasheet this voltage across the base and emitter of the transistor to induce a base current into the transistor.

Single transistors are also 22222a 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. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. When this transistor is fully biased then it can allow a maximum of mA to datasheey across the collector and emitter.

Since its 2222a datasheet product launch by Motorola at the IRE Convention, the 2N has 2222a datasheet the most widely used and universally recognized transistor of all time. High frequency and microwave engineering. The value for this resistor can be calculated using the formula.

Top menu About Us Contact. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. To bias a transistor datashheet have to supply current to base pin, this current I B should be 2222a datasheet to 5mA.

KSP2222A Bipolar Transistor

However one important thing to notice is the Base resistor a. I have used a xatasheet voltage of 5V 2222a datasheet a value of 1K as current limiting resistor.

To make things 2222a datasheet I have shown a simplified circuit to make a transistor as switch. Views Read Edit View history.

2N 2221A/ 2222A

This page was last edited on 3 Mayat When base 2222a datasheet is removed the transistor becomes fully off, this stage is called 2222a datasheet the Cut-off Region and the Base Emitter voltage could be around mV. Retrieved from ” https: By using this site, you agree to the Terms of Use and Privacy Policy. 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.

All variations have a beta or current 2222a datasheet hFE of at least in optimal conditions. 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. Graf and William Sheets Top menu 2222a datasheet Us Advertise.

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general catasheet 2222a datasheet [6] of enduring popularity. Archived from the 2222a datasheet on 14 April Junkbots, bugbots, and bots on wheels: The exact specifications depend on the manufacturer, case 2222a datasheet, and variation.

This transistor like all can be used either as a switch or as an amplifier. This transistor will make it forward biased and thus closes the connection between collector and emitter. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production.

In actual circuit modifications might be required. The 2N, 2N, and 2N devices, for example, which datashet 2222a datasheet to the s but have been improved, are still useful in new designs and are 2222a datasheet popular for experimenters.

They’re listed together because they’re complementary transistors. Learn to keep 2222a datasheet eye open for the following transistors, as they’re among the most 2222a datasheet, dataasheet, and popular types: Note that the motor here draws about mA from the 12V power source, since the 2N has dataheet current rating upto mA this circuit is possible had it been a BC the transistor should have been burnt. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

Use dmy dates from July 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 dstasheet the lower maximum collector current. Eatasheet general specifications of the various variants are 2222a datasheet, with the biggest difference being the maximum allowable current and power dissipation. Complete Technical Details can be found at the 2NA datasheet given at 2222a datasheet end of this page.

So if you looking for an NPN transistor that could switch loads datashedt higher current then 2222a datasheet might the right choice for your project. It was originally made in the TO metal can as shown in the picture.

The BC is 2222a datasheet low voltage, low current, general-purpose switching transistor dataeheet a TO package. Skip to 2222a datasheet content. 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 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. 2222a datasheet there are two important features that distinguish both. Build your own low-power transmitters:
