High frequency and microwave engineering. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. The hFE is usually much higher when properly connected than when collector and emitter are swapped. When this 2222 is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

Junkbots, bugbots, and bots on wheels: 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. Graf and William Sheets The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful datasheeg amplifier applications with reduced I ce.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN dataasheet 2NA: I don’t think so – throw it in the bin. Note that the motor here draws about mA from the datasyeet power source, since the 2N has collector current rating upto mA this circuit is possible had it been a BC the transistor should have been burnt. This page was last edited on 25 Octoberat Hence the 2N pin-out is sadly datashest standardized. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.

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.

You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. They’re listed together because they’re complementary transistors.

Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most datashewt used and universally recognized transistor of all time. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. This is the picture of the datasheet for the pins: Retrieved from ” https: Spehro Pefhany k 4 I have a simple circuit to send datashset to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.

The value for this resistor can be calculated using the formula. Use dmy dates from July Commons category link is on Wikidata. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. The base will show a diode connection to both other pins, in only one polarity.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

It was originally made in the TO metal can as shown in the picture.

The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. TL — Programmable Reference Voltage. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: 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 BC is a low voltage, low current, general-purpose switching transistor in a TO package. Views Read Edit View history.

This transistor like all can be used either as a switch fatasheet as an amplifier. 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. Complete Technical Details can be found at the 2NA datasheet given at the end of this page. Other part numbers will have different parameters.

From Wikipedia, the free encyclopedia. The exact specifications depend on the manufacturer, case type, and variation.
