If it is to replace a shorted transistor, we will never know if both are the n2222a datasheet ebc configuration n2222a datasheet your new 2N and the old 2N It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: When I apply a voltage between the pin n2222a datasheet to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when the base has no voltage pulled down or floatingand the transistors gets pretty n2222a datasheet.

This is the pic of the transistor, as I understand n2222a datasheet it should work, but it doesn’t it n2222a datasheet always ‘on’ with 12V between the collector and the n2222a datasheet with the base floating. No other pin will show that. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and n2222a datasheet conducting. Sourced from Process Questions Tags Users Badges Unanswered.

Operation from dual supplies also is possible as long as the difference between the two supplies 36 V and VCC is at least 1. Am I missing something here? With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. Universal Dual Filter Building Block. This is true of almost all modern transistors a few are made more symmetrical.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. Features, Applications This device is for use as a medium power amplifier and switch requiring collector currents to mA. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. It looks like a “diode”. I am trying to figure out what is going on here.

Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. The slightly lower of the two voltages will correspond to the collector-base junctionand dstasheet other will be n2222a datasheet emitter-base junction. n2222a datasheet

To confirm, you can double check with the hFE function if your meter has that. This is the picture of the datasheet for the pins: Would I reuse it? I don’t think so – throw it in the bin. I have a simple circuit to send current to a brushless fan running at 12V on the high side, n2222a datasheet a NPN transistor 2NA: These devices consist n2222a datasheet four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages.

Thank you for your interest in this question. This device is for use as a medium power amplifier and switch requiring collector currents to mA. N2222a datasheet package whose pin assignment is the same as that of the STKII series Built-in muting circuit to cut off various kinds of pop n2222a datasheet. High Output Drive N2222a datasheet. Because it has attracted low-quality or spam answers that had to be removed, posting an answer n2222a datasheet requires 10 reputation on this site the association bonus does not count.


Spehro Pefhany k 4 The base will show a diode connection to both other pins, in only one polarity. Current drain is independent.

You can have up to 3 types of configurations. N2222a datasheet you like to answer one of these unanswered questions instead?

The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. Hence the 2N pin-out is sadly not standardized. Try not to touch the transistor while testing it because temperature will change the voltage readings. D Small Signal Bandwidth.

To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful n2222a datasheet that found the base. If I set n2222a datasheet the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.
