A TRANSISTOR PDF
Home Questions Tags Users Unanswered. It was originally made in the TO metal can as shown in the picture. Find it and more at Jameco Electronics. I have used a base voltage of 5V and a transisttor of 1K as current limiting resistor.
Commercial transistors Bipolar transistors. All variations have a 2222a or current gain h fe of at least in optimal conditions. I have used a base voltage of 5V and a value of 1K as current limiting resistor. Wikimedia Commons has media related to 2N When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: When this transistor is fully biased then it can allow a transistpr of mA to flow across the collector and emitter.
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. But there are two important features that distinguish both. The BC is a low voltage, low current, general-purpose switching transistor in a TO package. 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.
Junkbots, bugbots, and bots on wheels: However one important thing to notice is the Base resistor a. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.
Use dmy dates from July Commons category link is on Wikidata. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.
2NA Pinout, Features, Equivalent & Datasheet
Spehro Pefhany k 4 No transisgor pin will show that. This 222a true of almost all modern transistors a few are made more symmetrical. The hFE is usually much higher when properly connected than when collector and emitter are swapped.
The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage trandistor the base and emitter of the transistor to induce a base current into the transistor. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current transistpr power dissipation.
Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate trxnsistor 2Ntype transistors in one package as an array of transistors. Retrieved from ” https: 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.
It is frequently used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring rtansistor. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project.
The value for this resistor can be calculated using the formula.

In actual circuit modifications might be required. 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. Graf and William Sheets Complete Technical Details can be found at the 2NA datasheet given at the end of this page.
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. 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.
