PN2222A Datasheet, Equivalent, Cross Reference Search
2222 As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.
To confirm, you can double check with the hFE function if your meter has that. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. 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 popularity. Spehro Pefhany k 4 Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. However one important thing to notice is the Base resistor dataaheet.
KSPA can allow collector current upto mA and also has power dissipation of mW which can be used to drive larger loads than compared with BC Tranistor to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: You can have up to 3 types of configurations.
It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Would you like to answer one of these unanswered questions instead?
2NA Pinout, Features, Equivalent & Datasheet
All variations have a beta or current gain h fe of at least in optimal conditions. The value for this resistor can be calculated using the formula. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. In actual circuit modifications might be required. The transistor will begin to conduct when the voltage across the Base and Emitter pin exceeds 0.
The capacitors C1 and C2 are simply used for filtering purpose.
But there are two important features that distinguish both. Zuofu 3, 2 15 Complete Dztasheet Details can be found at the 2NA datasheet given at the end of this page. Wikimedia Commons has media related to 2N 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.
The resistor R2 is used to limit the current though the collector of the transistor and is not mandatory. In other projects Wikimedia Commons. From Wikipedia, the free encyclopedia. If it is to replace a shorted transistor, we will datashheet know if both are the same ebc configuration between your new 2N and the old 2N Build your own low-power transmitters: They’re listed together because they’re complementary transistors.

With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. Normally this type of transistor will either be used as a switch or as an amplifier, both of which is discussed below.
It looks like a “diode”. Am I missing something here? Junkbots, bugbots, and bots on wheels: Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over four decades and are still being used in many designs.
When this transistor is fully biased then it can allow a maximum of mA to flow across the datashewt and emitter.
22222a transistors Bipolar transistors. TL — Programmable Reference Voltage. To make things simple I have shown a simplified circuit to make a transistor as switch. High frequency and microwave engineering. 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. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.
Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.
