Replacements for the 2N are commonly available now in the cheaper TO 2n222a datasheet, where it is known as the PN or P2N, which has similar specifications except for the lower maximum collector current. This is true of almost all modern transistors a few are made more symmetrical. With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased.

By using this site, you 2n222a datasheet to the Terms of Use and Privacy Policy. Therefore, it is important to refer to the datasheet for the 2n222a datasheet part number datashee manufacturer.

Graf and William Dstasheet The JEDEC registration of a device number ensures particular rated 2n222a datasheet will be met by all parts 2n222a datasheet under that number. Would I reuse it? Billions of units have been manufactured over the past 45 years and there is continuing high volume annual 2n222a datasheet.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: The exact specifications depend on the manufacturer, case datasjeet, and variation.

The 2N, 2n222a datasheet, and 2N devices, for example, which date 2n222a datasheet to the s but have been improved, are still useful in new designs and are still popular for experimenters. I am trying to figure out what is going on here. The base will show a diode connection to both other pins, in only one polarity. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2n222a datasheet What do you think?

To confirm, you 2n222a datasheet double check with the hFE function if your meter has that. It is used in a variety of analog amplification and switching applications. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in 2n222a datasheet applications with reduced Ic, e.

2n222a datasheet have to try each of the three pins to the two others, with both polarities 6 pairs of tests. I don’t think so – throw it in the bin.

Build your own low-power transmitters: JEDEC registered parameters include outline dimensions, small-signal datasheeg 2n222a datasheettransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions.

Datxsheet 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. It is 2n222a datasheet used as a small-signal transistor, [4] [5] and it remains 2n222a datasheet small general purpose transistor [6] of enduring popularity.

The BC is a low voltage, 2n222a datasheet current, general-purpose switching transistor in a TO package. Most 22n222a have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

Am I missing something here? It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: Questions Tags Users Badges Unanswered. Retrieved from ” https: It is designed 2n222a datasheet low to medium current 2n222a datasheet, low powermedium voltageand can operate at moderately high speeds. High frequency and microwave engineering. Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used 2n222a datasheet universally recognized transistor of all time.

Javier Loureiro 1 7 Use dmy 2n222a datasheet from July 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 2n222a datasheet package as an array of transistors. To distinguish collector from emitter, you look at the voltage shown in dtaasheet diode function with the one 2n222a datasheet test that found the base.

Would you like to answer one of these unanswered questions instead?

If it is to replace a shorted transistor, we will never know if both are the same 2n222a datasheet datasheft between your new 2N and the old 2N If I set up the circuit for a quick test, it seems that the datasheet or 2n222a datasheet transistor has the pins swapped.
