The hFE is usually much higher when properly connected than when collector and emitter are swapped.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. Would I transishor it? Other part numbers will have different parameters. One of the most default and primary function of a transistor is to act as a switch. This page was last edited on 25 Octoberat 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.

Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region. All variations have a datashete or current gain h fe of at least in optimal conditions. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.

But there are two important features that distinguish both. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

2222, bugbots, and bots on wheels: TL — Programmable Reference Voltage. 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. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Zuofu 3, 2 15 The vales of the Resistor in the above image are only for reference and are not accurate.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. 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 transistors gets pretty hot.

In this type of circuit, the Emitter and the Base pin of the transistor should be commonly connected to a same voltage, so we have connected it to the Ground potential using two resistors R4 transiwtor R3. Views Read Edit View history.

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 should have been burnt. But there are two important features that distinguish both. Spehro Pefhany k 4 If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.

The value for this resistor can be calculated using the formula. However this type of amplifiers have many drawback and if you are looking for some serious amplification applications then you should look into Op-Amps which are nothing but a package of many transistors put to gather with amplification as its sole purpose. The BC is a low voltage, low current, general-purpose switching transistor in a TO package. By using this site, you agree to the Terms of Use and Privacy Policy.

Another Common application of a Transistor is as amplifiers. TL — Programmable Reference Voltage. The transistor will begin to conduct when the voltage across the Base and Emitter pin exceeds 0.

From Wikipedia, the free encyclopedia. To make things simple I have shown a simplified circuit to make a transistor as switch.
