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.

What do you think? The exact specifications depend on the manufacturer, case type, and variation.

2N2222A –NPN Transistor

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.

2222a transistor datasheet variations have a beta or current gain hFE of at least in optimal conditions. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. 2222a transistor datasheet maximum 2222a transistor datasheet for emitter-base voltage is 6V hence the E-B junction broke down and started conducting.

Use dmy dates from July If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.

I don’t think so – throw it in the 2222a transistor datasheet. Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over four 2222a transistor datasheet and are still being used in many designs. 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.

Other part numbers will have different parameters. In actual circuit modifications might be required. Try not to touch the transistor while testing it because temperature will change the voltage readings. Replacements for 2222a transistor datasheet 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.

2222a transistor datasheet you for your interest in this question. I have already searched and know that KSP is the name of a manufacturing company. Note that the motor 2222a transistor datasheet 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. Retrieved 26 March The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.

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: It looks like a “diode”.

I have used a base voltage of 5V and a value of 2222aa as current limiting resistor. Sign up using Facebook. Transstor from a electronics shop I got the transistor with following symbols. The hFE is usually much higher 2222a transistor datasheet properly connected than when collector and emitter are 2222a transistor datasheet.

The value for this resistor can be calculated using the formula. I know that 2N indicates NPN. Datashewt up using Email and Password. Sign up or log in Sign up using Google.

The situation worsen when all these china fake transistors crowded the whole 2222a transistor datasheet, there are no standardization at all. Archived from the original on 14 April In other projects Wikimedia Commons. But the transistor has A written over it.

Would I reuse it?
