Zuofu 3, 2 15 When I apply a voltage between ratasheet 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. Complete Technical Details can be found at the 2NA datasheet given at the end of this page. However one important thing to notice is the Base resistor a.
The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. Commercial transistors Bipolar transistors. The 2N is considered a very common transistor,    and is used as an exemplar of an NPN transistor. I don’t think so – throw it in the bin.
2N Datasheet, Equivalent, Cross Reference Search. Transistor Catalog
This transistor will make it forward biased and thus closes the connection between collector and emitter. Would I reuse it? TL — Programmable Reference Voltage. This is the picture of the datasheet for the pins: But datasheett are two important features that distinguish both.

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. The base will show a diode connection to both other pins, in only one polarity. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.
Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production.
To make things simple I have shown a simplified circuit to make a transistor as switch. 2m222a have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: Javier Loureiro 1 7 Retrieved 26 March The exact specifications depend on the catasheet, case type, and variation. Graf and William Sheets You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. Use dmy dates from July Commons category link is on Wikidata.
How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The 2N exhibits its forward gain beta 2n222w at a lower current than the 2N, and is useful in 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 transistor 2NA:. Home Questions Tags Users Unanswered. This is the pic of the transistor, as I understand that it should work, but it doesn’t it is always ‘on’ with satasheet between the collector and the emitter with the base floating.
Retrieved from ” https: To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.
High frequency and microwave engineering.
In actual circuit modifications might be required. 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. Submitted by webmaster on 11 December Try not to touch the transistor while testing it because temperature will change the voltage readings.
