2NA Pinout, Features, Equivalent & Datasheet
Would I reuse it? Commercial transistors Bipolar transistors. Build your own low-power transmitters: I am trying to figure out what is going on here.
I have used a base voltage of 5V and a value of 1K as current limiting resistor. Thank you for your interest in this question. Wikimedia Commons has media related to 2N It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds.
Hence the 2N pin-out is sadly not standardized. The exact specifications depend on the manufacturer, case type, and variation.

When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. Spehro Transistod k 4 This transistor will make it forward biased and thus closes the connection between collector and emitter. 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.
Junkbots, bugbots, and bots on wheels: This is true of almost all modern transistors a few are made more symmetrical. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site trabsistor association bonus does not count.
The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. Transistoor frequency and microwave engineering. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.
It looks like a “diode”.
Retrieved 26 March I don’t think so – throw it in the bin. It was originally made in the TO metal can as shown in the picture. No other pin will show that. Next Article Timer IC.
Archived from the original on 14 April 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. Retrieved from ” https: Typical examples are tarnsistor 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.
2N 2221A/ 2222A
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. The value for this resistor can be calculated using the formula. All variations have a beta or current gain h fe of at least in optimal conditions. The BC is a low voltage, low current, general-purpose switching transistor in a TO package.
It is transjstor used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity.
The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. What do you think? This transistor like all can be used either as a switch or as an amplifier. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.
Note that the motor here draws about 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 tranxistor have been burnt.
