2N2222 Datasheet, Equivalent, Cross Reference Search
Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. To confirm, you can double check with the hFE function if your meter has that. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using 2n22a NPN transistor 2NA: It looks like a “diode”.
Home Questions Tags Users Unanswered. 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. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.
Am I missing something here?
With 2n22a wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. This is the picture of the datasheet for the pins: What do you datashwet Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: You can have up to 3 types of configurations.
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.

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 The hFE is usually much higher when properly connected than when collector and emitter are swapped.
It is used in dataeheet variety of analog amplification and switching applications. All variations have a beta or current gain h fe of at least in optimal conditions.
Note that the motor here draws about mA from the 12V power source, since the 2N has collector current rating upto mA this circuit is possible had it been a BC the transistor should have been burnt.
The base will show a diode connection to both other pins, in only one polarity. Applications Can be used to switch high current datasheett mA loads It can also be used in the various switching applications.
2NA Pinout, Features, Equivalent & Datasheet
No other pin will show that. This transistor like all can be daatsheet either as a switch or as an amplifier. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: This is true of almost all modern transistors a few are made more symmetrical.
TL — Programmable Reference Voltage.
The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. To distinguish collector from emitter, you look at the voltage shown in the diode function datzsheet the one successful test that found the base.
I have used a base voltage of 5V and 2m222a value of 1K as current limiting resistor. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.
