To distinguish collector from emitter, you look at the voltage shown in dtasheet diode function with the one successful test that found the base. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. Commercial transistors Bipolar transistors.
Zuofu 3, 2 15 I have used a base voltage of 5V and a value of 1K as current limiting resistor. 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. Try daatasheet to touch the transistor while testing it because temperature will change the voltage readings.
I am trying to figure out what is going on here.

Hence the 2N pin-out is sadly not standardized. It is used in a variety of analog amplification and switching applications. 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.
It is designed for low to medium currentlow powermedium voltageand can operate at ratasheet high speeds. It is daasheet used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity. But there are two important features that distinguish both. Home Questions Tags Users Unanswered. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. No other pin will show that.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. 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? Use dmy dates from July Commons category link is on Wikidata. In adtasheet circuit modifications might be required. The value for this resistor can be calculated using the formula.
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. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. From Wikipedia, the free encyclopedia.
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 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.
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 datasjeet does not count.
High frequency and microwave engineering. Javier Loureiro 1 7 This is the picture of the datasheet for the pins: Build your own low-power transmitters: I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.
You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. 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.
The base will show a diode connection to both other pins, in datashwet one polarity.
It looks like a “diode”. Graf and William Sheets
