2NA Pinout, Features, Equivalent & Datasheet

Try not to touch the transistor while testing it because temperature datashete change the voltage readings. So if you looking for an 2n22a transistor that could switch loads of higher current then 2NA might the right choice for your project. Would you like to answer one of these unanswered questions instead? 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 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce.

I am trying to figure out what is going on here. Other part numbers will have different parameters.

To make things simple I have shown a simplified circuit to make a transistor as switch. 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, even when the base has no voltage pulled down or floatingsatasheet the transistors gets pretty hot. I have a dataheet circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.

Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. You can have up to 3 types of configurations. To bias a transistor we have to supply current to base 2j222a, this current I B should be limited to 5mA. Absolute maximum rating for emitter-base voltage is 6V hence the Datasheef junction broke down and started conducting.

In other projects Wikimedia Commons. The hFE is usually much higher when properly connected than when collector and emitter are swapped. Archived from the original on 14 April Thank you for your interest in this question.

I don’t think so – throw it in the bin. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Submitted by webmaster on 11 December As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. With it wired the wrong way round the emitter is more positive than the collector and the base is reverse ratasheet. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will 22n22a the emitter-base junction.

In actual circuit modifications might be required.

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.

Am I missing something here? By using this site, you agree to the Terms of Use and Privacy Policy.

Commercial transistors Bipolar transistors. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage eatasheet, current rating, power dissipation and temperature rating, and others, measured under standard test conditions.

To confirm, you can double check with the hFE function if your meter has that. It looks like a “diode”.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. The value for this resistor can be calculated using the formula. However one important thing to notice is the Base resistor a.

Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.
