PNA. SMALL SIGNAL NPN TRANSISTOR. PRELIMINARY DATA s. SILICON EPITAXIAL PLANAR NPN. TRANSISTOR s. TO PACKAGE SUITABLE FOR. 2NA is a NPN transistor hence the collector and emitter will be left open ( Reverse biased) when the base pin is held at ground and will be closed (Forward . The 2N is a common NPN bipolar junction transistor (BJT) used for general purpose depend on the manufacturer, case type, and variation. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

You can have up to 3 types of configurations. Sign up or log in 222a up using Google. I don’t think so – throw it in the bin.
Would you like to answer 2222a transistor datasheet of these unanswered questions instead? To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.
This is true of almost all modern transistors a few are made more 2222a transistor datasheet. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. 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.
2NA Pinout, Features, Equivalent & Datasheet
Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and universally recognized 2222a transistor datasheet of all time. It was originally made in the TO metal can as shown in 2222a transistor datasheet picture.
The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. Build your trajsistor low-power transmitters: The hFE is usually trwnsistor higher 2222a transistor datasheet properly connected than when collector and emitter are swapped. Top menu About Us Contact. The JEDEC registration of a device number ensures particular rated transistro will be met 2222a transistor datasheet all parts offered under that number.
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 2222a transistor datasheet. Sign up using Email and Password.
So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. I know that 2N indicates NPN. JEDEC registered datasueet 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. Hence the 2N pin-out is sadly not standardized.
The exact specifications depend on the manufacturer, case type, and variation. That’s why I am not sure.

Thank you for your 2222a transistor datasheet in this question. Post as a guest Name. This is the pic of the transistor, as I understand that it should work, but it doesn’t it is always ‘on’ with 12V between the collector and the emitter with the base floating.
However one important thing to notice is the Base resistor 2222a transistor datasheet. Most 2Ns have the orientation which your diagram shows, where if the flat side is transistog you, the pins are E-B-C respectively.
