To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.

This is true of almost all modern transistors a few are made more symmetrical. You have dtaasheet try each of the three pins to the two others, with both polarities 6 pairs of tests.

ST Microelectronics

The slightly lower of the two voltages 22222a correspond to the collector-base junctionand the other will be the emitter-base junction. It is used in a variety of analog amplification and switching applications. Commercial transistors Bipolar transistors.

In actual circuit modifications might be required.

Am I missing datashheet here? To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

This transistor like all tgansistor be used either as a switch or as an amplifier. I have used a base voltage of 5V and a value of 1K as current limiting resistor.

Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.

How to use 2NA This transistor like all can be used either as a switch or as an amplifier. In other projects Wikimedia Commons. So if you looking for an NPN transistor that could switch loads of higher current then KSPA might the right choice for your project. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce.

No other pin will show that. Transistor as Amplifier Another Common application of a Transistor is as amplifiers.

This transistor will make it forward biased and thus closes the connection between collector and emitter. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. It looks like a “diode”. KSPA has a gain value of tothis value determines the amplification capacity of the transistor. To bias a transistor we have to supply current to base pin, this current I B should be trasnistor to 5mA.

Normally this type of transistor will either be used as a switch or as an amplifier, both of which is discussed below. Applications Can be used to switch high current upto mA loads It can datahseet be used in the various datashret applications. Retrieved 26 March 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.

KSPA can allow collector current upto mA and also has power dissipation of mW which can be used to drive larger loads than compared with BC To confirm, you can double check with the hFE function if your meter has that. Graf and William Sheets Archived from the original on 14 April Wikimedia Commons has media related to 2N I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.

Replacements for the 2N are commonly available now in the cheaper TO packaging, where it 2222 known as the PN or P2N, which has similar specifications except for the lower maximum datashset current. This is the picture of the datasheet for the pins: 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. So if you looking for an NPN transistor that could switch loads of higher current then transiistor might the right choice for your project.

Another Common application of a Transistor is as amplifiers. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region.
