Transistor Man looks at the current going from the base to the emitter. In the sixties and early seventies, Philips produced similar devices encapsulated in TO-3 packages 2h3094 the reference Dtaasheet described as being for “hifi” purposes and BDY38 although the BDY38 has lower voltage ratings than the 2N Variants with higher voltage ratings e.

Filed under beta hfe gain 2n tymkrs amplification transistor man transistors. It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids.

Archived from the original on The historically-significant 2N was designed by Herb Meisel’s engineering group with RCA; it was the first multi-amp silicon power transistor to sell for less than one dollar, and became an industry workhorse standard. The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N It is designed for low current and powermedium voltageand can operate at moderately high speeds.

Typical components that may require a transistor in order to be driven are motors, buzzers, solenoids, and high-power LEDs. In other projects Wikimedia Commons.

The maximum collector-to-emitter voltage for the 2N, like other transistors, depends on the resistance path the external circuit provides between the base and emitter of the transistor; with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.

Nevertheless, a 2N and many other power transistors originating from this era cannot be assumed to have great high-frequency performance and there can be degradation of phase-shift and open-loop gain even within the audio frequency range.

By using this site, you agree to the Terms of Use and Privacy Policy. This means they are both controlled by current applied to the base and provide current amplification at the collector-emitter end. These really are extreme conditions. The 2N is a much lower power version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.

The device is designed to operate with an efficient heatsink, but care must be taken to mount the device properly, [7] [8] [9] else physical damage or worsened power handling transisor result, especially with cases or heatsinks that are not perfectly flat. The art of electronics 2nd ed.

So in this way, the 2N does have superiority in that it can handle greater current. This means the 2N will suffice perfectly fine for these applications. The KD have higher power and higher current than 2N By using this site, you agree to the Terms of Use and Privacy Policy.

The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers.

Retrieved from ” https: It often has a transition frequency of around 3. Commons category link is on Wikidata. Retrieved from ” https: However, when you are dealing with electronics, unless you are in power electronics, you xatasheet pretty much never need amperage this high.

Other manufacturers around this time also would specify similar values e. Retrieved 31 October However, it doesn’t necessarily mean it’s the transistor that you should use.

In simplicity, this really means that 40V is the maximum amount of voltage that the transistor can tolerate minus the voltage drop across the load connected to the collector. Below is a table of the comparison and contrast of the transistors, with an explanation of what everything in the table means below it.

Wikimedia Commons has media related to 2N KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. Graf; William Sheets Datassheet the sheet above, it is also known as as hFE. It was produced exclusively transietor the Czechoslovakian electronics company Tesla.

So a bunch of the folks were talking about engineering and electronics and the like in our irc room and I got to talking about how engineers love smashing a whole bunch of letters and numbers together to make chip names sound ridiculous.

Modern 2N datasheets often, but not always, specify f T of 2.

It is used in a variety of analog amplification and switching applications. It has a transition frequency of 2. If you need greater than mA but less than 1A, then the 2N will be the one to use. Since the early s, the 2N transistor has been heavily targeted by counterfeiters, who substitute much smaller silicon dies with lesser power ratings, use inferior mounting techniques, and fake the markings.

A 2N can handle up to mA milliamperes of current flow from the emitter to collector terminal.
