2NA Pinout, Features, Equivalent & Datasheet

The value for this resistor can be calculated using the formula. All variations have a beta or current gain h fe of at least in optimal conditions. The general specifications of transistog various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. In actual circuit modifications might be required. It is used in a variety of analog amplification and switching applications.

However one important thing to notice is the Base resistor a. By using this site, you agree to the Terms of Use and Privacy Policy. 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. I have used a base voltage of 5V and a transisttor of 1K as current limiting resistor. 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.

Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

Zuofu 3, 2 15 Am I missing something here? This is true of almost all modern transistors a few are made more symmetrical. Browse over 30, products, including Electronic Components, Computer Products.

The JEDEC registration of a device transiator ensures particular rated values will be met by all parts offered under that number. 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. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

It is frequently used as a small-signal transistor, trwnsistor [5] and it remains a small general purpose transistor [6] of enduring popularity. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.

Commercial transistors Bipolar transistors. High frequency and microwave engineering. The hFE is usually much higher when properly connected than when collector and emitter are swapped. 2222a — Programmable Reference Voltage. All variations have a beta or current gain h fe of at least in optimal conditions. I have a simple circuit to send current to a brushless tranaistor running at 12V on the high side, using a NPN transistor 2NA:.

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 22222a still being used in many designs.

Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.

Use dmy dates from July Commons category link is on Wikidata. 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 tranaistor lower maximum collector current.

To make things simple I have shown a simplified circuit to make a transistor as switch. 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.

Billions of units have been manufactured over the trznsistor 45 years and there is continuing high volume annual production. Looking for transisto transistor? It was originally made in the TO metal can as shown in the picture. 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. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from trajsistor.
