Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and universally recognized translstor of all time. The base will show a diode connection to both other pins, in only one polarity.

The base pin of the transistor has to be biased with a voltage; this voltage is provided by the potential divider network formed by the resistors R4 and R6.

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. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.

As the name suggests this resistor will limit the current datasbeet through the transistor to prevent it from damaging.

KSPA Transistor Pinout, Features, Equivalent & Datasheet

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. Am I missing something here?

The slightly datasheer of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. From Wikipedia, the free encyclopedia. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. There are many types of amplifier circuits that are possible with transistor but this is the datasehet commonly used one because it is very good in amplifying low frequency voltage signals like audio signals.

Graf and William Sheets I am datashet to figure out what is going on here. Thank you for your interest in this question. 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. 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.

Archived from the original on 14 April Because it has attracted low-quality or spam answers that had to be removed, posting an trnasistor now requires 10 reputation on this site the association bonus does not count. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. What do you think? 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.

Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. Retrieved from ” https: So if you looking for transistoe NPN transistor that could switch loads of higher current then 2NA might the right choice for your project.

So if you looking for an NPN transistor that could switch loads of higher current then KSPA might the right choice for your project. I have used a base voltage of 5V and a value of 1K as current limiting resistor. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

One of the most default and primary function of a transistor is to act as a switch. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. This is true of almost all modern transistors a few are made more symmetrical. Would I reuse it?

With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. Commercial transistors Bipolar transistors.

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. Another Common application of a Transistor is as amplifiers. However one important thing to notice is the Base resistor a.

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.

ST Microelectronics

Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. The transistor will begin to conduct when the voltage across the Base and Emitter pin exceeds 0.

KSPA is a NPN transistor hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and will be closed Forward biased when a signal is provided to base pin. By using this site, datasbeet agree to the Terms of Use and Privacy Policy.

The maximum amount of current that could flow through the Collector 2222w is mA, hence we cannot connect loads that consume more than mA using this transistor. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

The capacitors C1 and C2 are simply used for filtering purpose. The value for this resistor can be calculated using the formula. Build your own low-power transmitters: When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region.

It is tranisstor for low to medium currentlow powermedium voltageand teansistor operate at moderately high speeds. To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. Submitted by admin on 24 June
