So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

2NA Pinout, Features, Equivalent & Datasheet

Commercial transistors Bipolar transistors. Skip to main content. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. This is the picture of the datasheet for the pins: I have a simple circuit to send current to a brushless fan running at 12V on rransistor high side, using a NPN transistor 2NA:.

Transistr situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. 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. I don’t think so – throw it in the bin. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. This is true of almost all transkstor transistors a few are made more symmetrical. The BC is a low voltage, low current, general-purpose switching transistor in a TO package.

The exact specifications depend on the manufacturer, case type, and variation. 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. Top menu About Us Contact. It is used in a variety of analog amplification and switching applications. Home Questions Tags Users Unanswered.

Zuofu 3, 2 15 To make things simple I have shown a simplified circuit to make a transistor as switch. However one important thing to notice is the Base resistor a. Build your own low-power transmitters: Junkbots, bugbots, and bots on wheels: Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. Use dmy dates from July They’re listed together because they’re complementary transistors.

  INTRODUCING ZBRUSH 4 BY ERIC KELLER PDF

Transisotr 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce. This transistor like all can be used either as a switch or as an amplifier.

2N 2221A/ 2222A

The value for this resistor can be calculated using the formula. I have used 2222s base voltage transjstor 5V and a value of 1K as current limiting resistor. 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.

Other part numbers will have different parameters. Javier Loureiro 1 7 You can have up to 3 types of configurations.

This transistor will make it forward biased and thus closes the connection between collector and emitter. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

Retrieved 26 March 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. If I set up the transjstor for a quick test, it 22222a that the datasheet or the transistor has the pins swapped.
