So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

Build your own low-power transmitters: The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in 2n222 applications with reduced I ce. It can be even worse, since the Datasyeet Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: All variations have a beta or current gain h fe of at least in optimal conditions.

It looks like a “diode”.

This is true of almost all modern transistors a few are made more symmetrical. To confirm, you can double check with the hFE function if your meter has that.

Most 2Ns have the orientation which your diagram shows, where if the flat datashheet is facing you, the pins are E-B-C respectively.

Daasheet have used a base voltage of 5V and a value of 1K as current limiting resistor. 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. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. Absolute maximum rating for emitter-base voltage is datasgeet hence the E-B junction broke down and started conducting.

Use dmy dates from July Commons category link is on Wikidata. It is used in a variety of dztasheet amplification and switching applications. What do you think? The BC is a low voltage, low current, general-purpose 2n22a2 transistor in a TO package. Would I reuse it? Retrieved 26 March Views Read Edit View history. 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.

Thank you for your interest in this question. 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. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. By using this site, you agree to the Terms of Use and Privacy Policy. They’re listed together because they’re complementary transistors.

The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. I don’t think so – throw it in the bin. Javier Loureiro 1 7 It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. Junkbots, bugbots, and bots on wheels: 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. The hFE is usually much higher when properly connected dztasheet when collector and emitter are swapped.

The value for this resistor can be calculated using the formula. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

When base current is removed the datasheet becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.

To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. Am I missing something here? Retrieved from ” https: It was originally made in the TO metal can as shown in the picture. Submitted by webmaster on 11 December I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: 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 does not count.

It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. The exact specifications depend on the manufacturer, case type, and variation. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. This page was last edited on 25 Octoberat

Thank you for your interest in this question. Build your own low-power transmitters: 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.

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 In other projects Wikimedia Commons.

This is true of almost all modern transistors a few are made more symmetrical. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the datasheett to induce a base current into the transistor.

Views Read Edit View history. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.

You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. I have used a base voltage of 5V and a value of datasheet as current limiting resistor. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.
