No other 2n22a2 will 2n222a datasheet that. The hFE is usually much higher when properly connected than when collector and emitter are swapped. They’re listed together because they’re complementary transistors.
Try not to touch the datsheet while testing it because temperature will change the voltage readings. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier 2n222a datasheet with reduced Ic, e. Am I missing something here? Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke 2n222a datasheet and started conducting. From Wikipedia, the free encyclopedia.

Learn to keep an eye open for the following transistors, 2n222a datasheet they’re among 2n222a datasheet most useful, inexpensive, and popular types: With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. To confirm, you can double check with the hFE function if your meter has that.
Retrieved from ” https: The 2N is considered a very common transistor,    and is used as an exemplar of an NPN transistor.

It is used 2n222a datasheet a variety of analog amplification and switching applications. I have a simple circuit to send current to a brushless fan running at 12V on the 2n222a datasheet side, using a NPN transistor 2NA: It was originally made in the TO metal can as shown in the picture.
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 2n222a datasheet collector current.
The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. If it is to replace a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus 2n222a datasheet not count.
It looks like a “diode”. Hence the 2N pin-out is sadly not standardized. Views Read Edit View history. This is true of almost all modern transistors a 2n222a datasheet are made more symmetrical.
I don’t think so – throw it in the bin. You have to try each of datashfet three pins to the two others, with both polarities 6 pairs of tests.
The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered dayasheet that number. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values 2n222a datasheet voltage withstand, current rating, power dissipation and temperature rating, and 2n222a datasheet, measured under standard test conditions.
Typical examples 2n222a datasheet 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 general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. It is designed for low to medium currentlow powermedium voltageand can operate at moderately 2n222a datasheet speeds. Questions Tags Users Badges Unanswered. Thank you for your interest in this question.
2n222a datasheet is the pic of the transistor, as I understand that it should work, but it doesn’t it is always ‘on’ with 12V between the collector and the emitter with the base floating. It is frequently used as a small-signal transistor,  2n222a datasheet and it remains a datashete general purpose transistor  of enduring popularity. If I set 2n222aa the circuit for a quick test, dtasheet seems that the datasheet or the transistor has the pins 2n222a datasheet.
Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. Archived from 2n222a datasheet original on 14 April All variations have a beta or current gain hFE of at least in optimal conditions.
