PNA. SMALL SIGNAL NPN TRANSISTOR. PRELIMINARY DATA s. SILICON EPITAXIAL PLANAR NPN. TRANSISTOR s. TO PACKAGE SUITABLE FOR. 2NA 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 . The 2N is a common NPN bipolar junction transistor (BJT) used for general purpose depend on the manufacturer, case type, and variation. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

It can be even worse, 2222a transistor datasheet the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: Build your own low-power transmitters: The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across trandistor base and emitter of the transistor to induce a base current into the transistor.

What do you think? Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. In actual circuit modifications might be required. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

So thanks a lot for helping me. 2222a transistor datasheet Commons has media related to 2N From Wikipedia, 22222a free encyclopedia. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.

Complete Technical Details can be 2222a transistor datasheet at the 2NA datasheet given at the end of this page. Thank you for your interest in this question.


npn – Question regarding transistor codes – Electrical Engineering Stack Exchange

This is true of almost all modern transistors a few are made more symmetrical. With it wired the wrong way round the 2222a transistor datasheet is more positive than the collector and the base is 2222a transistor datasheet biased. Commercial transistors Bipolar transistors. Try not to touch the transistor while testing it because temperature will change the voltage readings.

2222a transistor datasheet know that 2N indicates NPN. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. This page was last edited on 3 Mayat It was originally made in the TO metal can as shown in the picture. 2222a transistor datasheet is used in a variety of analog amplification and switching applications.

Javier Loureiro 1 7 The base will show a diode connection to both other pins, in only one polarity.

I needed a 2N A transistor. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. To make 2222a transistor datasheet simple I have shown a simplified 2222a transistor datasheet to make a transistor as switch. Questions Tags Users Badges Unanswered.

I am trying to figure out what is trnasistor on here. 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.

This is the pic of the transistor, as I 2222a transistor datasheet that it should work, but it doesn’t it is always ‘on’ with 12V between the collector and the emitter with the base floating.

KSP2222A Bipolar Transistor

All variations have a beta or current gain hFE of at least in optimal conditions. Am I missing something here? In other projects Wikimedia Commons. Questions Tags Users Badges Unanswered. The exact specifications depend on the manufacturer, case 2222a transistor datasheet, and variation.


Graf and William Sheets Spehro Pefhany k 4 The 2N is an NPN transistor that can only 2222a transistor datasheet one-third the current of the 2N but has otherwise similar characteristics. Next Article Timer IC. I have already searched and know that KSP is the name of a manufacturing company. When this transistor is fully biased then 2222a transistor datasheet can allow a maximum of mA to flow across the collector and emitter.

Junkbots, bugbots, and bots on wheels: This is the picture 2222a transistor datasheet the datasheet for the pins: JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequency 2222a transistor datasheet, maximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions.

Hence the 2N pin-out is sadly not standardized. And from a electronics shop I got the transistor with following symbols.

Top menu About Us Contact. Retrieved 26 March Learn darasheet keep an eye open for 2222a transistor datasheet following transistors, as 2222a transistor datasheet among the most useful, inexpensive, and popular types: 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.

To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. Post as a guest Name. The value for this resistor 2222a transistor datasheet be calculated using the formula.
