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. As the name suggests this transisgor will limit the current flowing through the transistor to prevent it from damaging. However one important thing to notice is the Base resistor a.

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.
This page was last edited on 25 Octoberat This transistor like all can be used either as translstor switch or as an amplifier. Submitted by webmaster on 11 December It is frequently used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. The exact specifications depend on the manufacturer, case type, and variation.
High frequency and microwave engineering.
Retrieved from ” https: But there are two important features that distinguish both. Zuofu 3, 2 15 Am I missing something here? It is used in a variety of analog amplification and switching applications.

Home Questions Tags Users Unanswered. I have a simple circuit to send current to a brushless fan running at 22222a on the high side, using a NPN transistor 2NA:.
Wikimedia Commons has media related to 2N 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 BC is a low voltage, transkstor current, general-purpose switching transistor in a TO package. The 2N is considered a very common transistor,    and is used as an exemplar of an NPN transistor. It is used in a variety of analog amplification and switching applications. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
Archived from the original on 14 April 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.
As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. In actual circuit modifications might be required.

Views Read Edit View history. They’re listed together because they’re complementary transistors. 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.
Applications Can be used to switch high current upto mA loads Transistof can also be used in the various switching applications. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.
From Wikipedia, the free encyclopedia. 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 designed for low to medium currentlow powermedium voltageand can operate at transidtor high speeds. To make things simple I have shown a simplified circuit to make a transistor as switch.
Find it and more at Jameco Electronics. 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.
2222A TRANSISTOR PDF
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. Retrieved 26 March It is frequently used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity.
How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.
Since its initial product launch by Transostor at the IRE Convention, the 2N has become the most widely used and universally recognized transistor of all time. In other projects Wikimedia Commons.
Graf traneistor William Sheets When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, transostor when the base has no voltage pulled down or floatingand the transistors gets pretty hot.
