The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs and are still popular for experimenters.

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

Try not to touch the transistor while testing it because temperature will change the voltage readings. No other pin will show that. Build your own low-power transmitters: Commercial transistors Bipolar transistors.

Absolute maximum rating for emitter-base voltage is 6V datasjeet the E-B junction broke down and started conducting. With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. I have used a base voltage of 5V and a value of 1K as current limiting resistor.

2NA Pinout, Features, Equivalent & Datasheet

You can have up to 3 types of configurations. It was originally made in the TO metal can daatasheet shown in the picture. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions.

However one important thing to notice is the Base resistor a.

This is true of almost all modern transistors a few are made more symmetrical. Complete Technical Details can be dahasheet at the 2NA datasheet given at the end of this page.

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 situation worsen 2n22a all these china fake transistors crowded the whole dafasheet, there are no standardization at all.


The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production.

Zuofu 3, 2 15 When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. Junkbots, bugbots, and bots on wheels: 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.

The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. As the name 2n22a this resistor will limit the current datasyeet through the transistor to prevent it from damaging.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. I have a simple circuit to send current to a brushless fan running at 12V on the high side, vatasheet a NPN transistor 2NA: Other part numbers will have different parameters.

How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The value for this resistor can be calculated using the formula.

This is the pic of the transistor, 2n222 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. I am trying to figure dataeheet what is going on here.


Therefore, it is important to refer to the datasheet for 2j222a exact part number and manufacturer.

This is the picture of the datasheet for the pins: Wikimedia Commons has media related to 2N Would you like to answer one of these unanswered questions instead?

It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Thank you for your interest in this question.

2N2222 Datasheet, Equivalent, Cross Reference Search

It looks like a “diode”. The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Submitted by webmaster on 11 December TL — Programmable Reference Voltage. All variations have a beta or current gain h fe of at least in optimal conditions.

I don’t think so – throw it in the bin. To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.

Datashert make things simple I have shown a simplified circuit to make a transistor as switch. Retrieved from ” https: Datadheet I apply a voltage between the pin 1 to 2n22a2, 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 hot.

What do you think? Graf and William Sheets Javier Loureiro 1 7 It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly datashewt specifications: 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 one package as an array of transistors.
