When 2n22a 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 floatingand the transistors gets pretty hot. But there are two important features that distinguish both. Archived from the original on 14 April Try not to touch the transistor while testing it because temperature will change the voltage readings.

To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.

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.

Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. What do you think?

Other part numbers will have different parameters. I am trying to figure out what is going on here. In actual circuit modifications might be required. When base current is removed datadheet transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV.

The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

I have a eatasheet circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. Hence the 2N pin-out is sadly not standardized.

To make things simple I have shown a simplified circuit to make a transistor as switch. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.

The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

Javier Loureiro 1 7 As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. How to use 2NA This transistor like all can be used either as a switch or as an amplifier. You can have up to 3 types of configurations. Absolute maximum dataseet for emitter-base voltage is 6V hence the E-B junction broke down and started conducting.

High frequency 2n222s microwave engineering.

No other pin will show that. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. They’re listed together because they’re complementary transistors. Zuofu 3, 2 15 From Wikipedia, the free encyclopedia. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: All variations have a beta or current gain h fe of at least in optimal conditions.

2NA Pinout, Features, Equivalent & Datasheet

Applications Can be used to switch high current upto mA loads It can also be used in datashset various switching applications. 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.

If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped. 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 BC is a low voltage, low current, general-purpose switching transistor in a TO package.

TL — Programmable Reference Voltage. Use dmy dates from July Commons category link is on Wikidata. 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.

With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate datasheeh 2Ntype transistors in one package as an array of transistors.
