Other part numbers will have different parameters.
Thank you for your interest in this question. Home Questions Tags Users Dattasheet. You can have up to 3 types of configurations. To make things simple I have shown a simplified circuit to make a transistor as switch. If I set up the circuit for a quick test, it seems that the datasheet or the dstasheet has the pins swapped. The hFE is usually much higher when properly dtaasheet than when collector and emitter are swapped.
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.
Spehro Pefhany k 4 The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Build your own low-power transmitters: 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.
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.
The base will show a diode connection to both other pins, in only one polarity. Graf and William Sheets Archived from the original on 14 April Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
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 floatingand the 2b222a gets pretty hot.
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. This is the picture of the datasheet for the pins: The 2N is considered a very common transistor,    and is used as an exemplar of datashedt NPN transistor.
2NA Pinout, Features, Equivalent & Datasheet
They’re listed together because they’re complementary transistors. Complete Technical Details can be found at the 2NA datasheet given at the end of this page. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. I have used a base voltage of 5V and a value of 1K as current limiting resistor. It is designed for low daatsheet medium currentlow powermedium voltageand can operate at moderately high speeds.
Try not to touch the transistor while testing it because temperature will change the voltage readings. It is used in a variety of analog amplification and switching applications. With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. No other pin will show that.
Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: Datashedt am trying to figure datashet what is going on here. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: All variations have a beta or current gain h fe of at least in optimal conditions.
Am I missing something here? But there are two important features that distinguish both. dataasheet
2N2222 Datasheet, Equivalent, Cross Reference Search
How to use 2NA This transistor like all can be used either as a switch or as an amplifier. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting.

As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. Commercial transistors Bipolar datashet. The 2N exhibits its forward gain datashet peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce.
