This is the picture of the datasheet for the pins: JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation fatasheet temperature rating, and others, measured under standard test conditions.

All variations have a beta or current gain h fe of at least in optimal conditions. It can be even worse, since the On Semi PN has the conventional 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.

Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. 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.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. Would you like to answer one of these unanswered questions instead? To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Home Questions Tags Users Unanswered. Note that the motor here draws datasjeet mA from the 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 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.

When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when the base has no voltage pulled down or floatingdatasheer the transistors gets pretty hot. The BC is a low voltage, low current, general-purpose switching transistor in a TO package.

Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. Retrieved 26 March It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. This transistor like all can be used either as a switch or as an amplifier. It is used in a variety of analog amplification and switching applications. The value for this resistor can be calculated using the formula.

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 slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. What do you think?

Hence the 2N pin-out is sadly not standardized. From Wikipedia, the free encyclopedia. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. When this transistor 2n2222a fully biased then it can allow a maximum of mA to flow across the collector and emitter.

2NA Pinout, Features, Equivalent & Datasheet

I have a simple circuit to send current to a brushless fan running at 12V on the daatasheet side, using a NPN transistor 2NA: It was originally made in the TO metal can as shown in the picture. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.

Build your own low-power transmitters: The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.

Use dmy dates from July Commons category link is on Wikidata. The exact specifications depend on the manufacturer, case type, and variation. This transistor will make it forward biased and thus closes the connection between collector and emitter.
