The KD have higher power and higher current than 2N The 2N is a silicon NPN power transistor intended for general purpose applications. Below is a table of the comparison and contrast of the transistors, with an explanation of what everything in the table means below it. In the sixties and transitsor seventies, Philips produced similar devices encapsulated in TO-3 packages under the reference BDY20 described as being for “hifi” purposes and BDY38 although the BDY38 has lower voltage ratings than the 2N The 2N and the 2N are 2 of the most popular NPN bipolar junction transistors in the electronics market.

In these ways, the 2N and the 2N are both identical. Datasheef means the 2N will suffice perfectly fine for these applications.

So the choice ultimately depends on how much current is needed. If you need greater than mA but less than 1A, then the 2N will be the one to use.


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. The complementary PNP transistor trxnsistor 2N So in this way, the 2N does have superiority in that it can handle greater current.

Motors, for example, typically require in the range of about 75mA to power on. And if you need greater than 1A at the output, then a darlington transistor such as the TIP transistor can be used, which can handle up to 5A of amplified current.

KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. Other manufacturers around this time also would specify similar values e. These all normally require much less than mA to be powered on.

This wouldn’t be acceptable, since it exceeds the maximum V CEO. It is designed for low current and powermedium voltageand can operate at moderately high speeds.

This means they are both controlled by current applied to the base and provide current amplification at the collector-emitter end.

How they differ is that the 2N can handle greater operating collector current. Commons category transisfor is on Wikidata. Wikimedia Commons has media related to 2N The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications.

This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. However, when you are dealing with electronics, unless you are in power electronics, you will pretty much never need amperage this high.

Now hFE and beta cannot be greater in value than allowed by the gain. These really are extreme conditions. Since the early s, the 2N transistor has been heavily targeted by counterfeiters, who substitute much smaller silicon dies with lesser tranisstor ratings, use inferior mounting techniques, and fake the markings.
