Archived from the original on 14 April All variations have a beta transistoe current gain hFE of at least in optimal conditions. In other projects Wikimedia Commons.

From Wikipedia, the free encyclopedia.

The general specifications of the various variants transitor similar, with the biggest difference being the maximum allowable current and power dissipation. The BC is a low voltage, low current, general-purpose switching transistor in a TO transistor 2222a. The 2N, 2N, and 2N devices, for example, which date back to the s but have transistor 2222a improved, are still useful in new designs and are still popular for experimenters.

It was originally made in the TO metal can as shown in the picture. Learn to keep transistor 2222a eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: 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 for the lower maximum collector current.

It is transistor 2222a for low to medium currentlow transistor 2222amedium 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 universally recognized transistor of all time. Retrieved from ” transistor 2222a Commercial transistors Bipolar transistors.

Transistor 2222a frequency and microwave engineering. They’re listed together because they’re complementary transistors. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. 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. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.


Transistor 2222a Commons has media related to 2N Retrieved transistor 2222a March The 2N is an NPN transistor that can only switch one-third the current of the 2N but has transistor 2222a similar characteristics.

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. It is used in a variety of analog amplification and switching applications.

Graf and William Sheets Therefore, it is important to refer to the datasheet for the transistor 2222a part number and manufacturer. Other part numbers will have different parameters.

Single transistors are also available in several different transistor 2222a mount packages, and a number of manufacturers market transistor 2222a mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.

Build your own low-power transmitters: 22222a JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.
