But there are two important features that distinguish both. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. By using this site, you agree to the Terms of Use and Privacy Policy. The BC is a low voltage, low current, general-purpose switching transistor in a TO package.

What do you think? It looks like a “diode”. Build your own low-power transmitters: It is used in a variety of analog amplification and switching applications. Zuofu 3, 2 15 You can have up to 3 types of configurations.

It can be even worse, since the On Semi PN has the dahasheet pinout, despite being the same manufacturer and mostly same specifications: It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds.

TL — Programmable Reference Voltage. Hence the 2N pin-out is sadly not standardized. How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

2NA Pinout, Features, Equivalent & Datasheet

Try not to touch the transistor while testing it because temperature will change the datasueet readings. The base will show a diode connection to both other pins, in only one polarity. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production.

I don’t think so – throw it in the bin. To make things simple I have shown a simplified circuit to make a transistor as switch. 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 datasheey current.

This transistor will make it forward biased and thus closes the connection between collector and emitter. Would I reuse it?

Spehro Pefhany k 4 I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.

It was originally made in the TO metal can as shown in the picture. Views Read Edit View history. This transistor like all can be used either as a switch or as an amplifier.

In actual circuit modifications might be required. Would you like to answer one of xatasheet unanswered questions instead? Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and universally recognized transistor of all time.

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 an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting.

They’re listed together because they’re complementary transistors. However one important thing to notice is the Base resistor a. To bias a transistor we have to supply current to base pin, this current I Dztasheet should be limited to 5mA. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.

All variations have a beta or current gain h fe of at least in optimal conditions. I have used a base voltage of 5V and a value of 1K as current limiting resistor. Submitted by webmaster on 11 December Other part numbers will have different parameters. No other satasheet will show that. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. The exact specifications depend on the manufacturer, case type, and variation.

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.

Junkbots, bugbots, and bots on wheels: Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: Retrieved 26 March This is the picture of the datasheet for the pins: Archived from the original on 14 April Javier Loureiro 1 7 To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.

To 2n222a, you can double check with the hFE function if your meter has that.
