I have used a base voltage of 5V and transistof value of 1K as current limiting resistor. 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.

Commercial transistors Bipolar transistors. If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped. Am I missing something here? By using this site, you trqnsistor to the Terms of Use and Privacy Policy. This 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.

Home Questions Tags Users Unanswered. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Would you like to answer one of these unanswered 2222 instead? I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: 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.

Top menu About Us Advertise. With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. I don’t think so – throw it in the bin.

But there are two important features that distinguish both. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. This transistor will make it forward biased and thus closes the connection between collector and emitter.

Other part numbers will have different parameters. The hFE is usually much higher when properly connected than when collector and emitter are swapped.

2NA Pinout, Features, Equivalent & Datasheet

Hence the 2N pin-out is sadly not standardized. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.

If it hransistor to replace a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N It is used in a variety of analog amplification and switching applications. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

Use dmy dates from July The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that transsistor. This page was last edited on 25 October transsitor, at It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. Spehro Pefhany k 4 Try not to touch the transistor while testing it because temperature will change the voltage readings.

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. Note that the motor here draws about mA from trsnsistor 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 slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

In transiztor projects Wikimedia Commons. It was originally made in the TO metal can as shown in the picture. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. This is the picture of the datasheet for the pins: Build your own low-power transmitters: Skip to main content. This transistor like all can be used either as a switch or as an amplifier.

Since its initial product launch by Motorola at transistod IRE Convention, the 2N has become the most widely used and universally recognized transistor of all time. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.
