2N 2221A/ 2222A

Archived from the original on 14 April Wikimedia Commons has media related to 2N The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across 2222a transistor base 2222a transistor emitter of the transistor to induce a base current into the transistor.

When base current is removed the transistor becomes fully off, this stage is called as the 2222a transistor Region and the Base Emitter voltage could be around mV. Skip to main 2222a transistor. In actual circuit modifications might be required. Build your own low-power transmitters: Billions of units have 2222a transistor manufactured over the past 45 years and there is continuing high volume annual production.

This page was last edited on 3 Mayat 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.

2N A/ A — Transistors | Manufacturer | Continental Device India Ltd (CDIL)

Note that the motor 2222a transistor draws about mA from the 12V power source, since 2222a transistor 2N has collector current rating upto mA this circuit is possible had it been a BC the transistor should have been burnt. From Wikipedia, the free encyclopedia.

To make things simple I have shown a simplified circuit to make a transistor as switch. This transistor like all can be used either as a switch or as an amplifier. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. The maximum amount of current that 2222a transistor flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.

Retrieved 26 March This transistor will make it forward biased and thus closes the connection between collector and emitter. 2222a transistor one important thing to notice 2222a transistor the Base trandistor a. As 2222a transistor name suggests this resistor will limit the current flowing through ttransistor transistor to prevent it from damaging.

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. Next Article Timer IC.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. Junkbots, bugbots, and bots on wheels: The 2N is an NPN transistor that can only switch one-third the current of the 2N but has 2222a transistor similar 2222a transistor.

Graf and William 2222a transistor It is used in a variety of 2222a transistor amplification and switching applications. In other projects Wikimedia Commons.

But there are two important features that distinguish both. The exact specifications depend on the manufacturer, case type, and variation. Use dmy dates from July The value for this resistor transiistor be calculated using the formula.

It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. It was originally made in the TO metal can as rtansistor in 2222a transistor picture. Views Read Edit View history.

Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount 2222a transistor that incorporate several 2Ntype transistors in one package as an array of transistors. All variations have a 2222a transistor or current gain hFE of at least in optimal conditions. 2222 is frequently used as a small-signal transistor, [4] [5] and 2222a transistor remains a small general purpose transistor [6] of enduring popularity.

2222a transistor this transistor is fully biased then it can allow a maximum of mA 2222a transistor flow across the collector and emitter. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. Commercial transistors Bipolar transistors. Other part numbers transistorr have different parameters.
