The art of electronics 2nd ed. I guess the 31 is the 31st week of the year, then. Retrieved 7 November No transistors prefixed ‘ON’ at all. Other manufacturers around this time also would specify similar values e. RCA by had changed their specification to give 2.

Also the higher frequency response has improved performance when used in audio amplifiers. 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 adtasheet with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.

An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N Sign up using Facebook. But there’s a date code on the part, so maybe it’s a newer type than the book. Wikimedia Commons has media related to 2N The robot builder’s bonanza 2nd ed.

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 datashfet phase-shift and open-loop datawheet even within the audio frequency range.

It is by now unlikely to actually obtain a genuine datasheeh transistor when using popular sales platforms such as Amazon or Ebay; classic electronics distributors are mostly still able to properly source them.

And here’s what the pins look from the other side they’re datashedt long metal tabs that come from the case, around the middle of ke503 picture:. Commons category link from Wikidata.

Philips ON F It’s used to drive 4 injectors simultaneously, in this configuration: The frequency at which gain begins to drop off may be much lower, see below.

Build your own low-power transmitters: Sometimes the V CBO breakdown voltage the maximum voltage between collector and base, with the emitter open, an unrealistic arrangement in practical circuits is given as the only voltage rating, kd5503 can cause confusion. Having reverse-engineered the circuit, I’m fairly certain that it’s a NPN transistor, but I’ve found some references mentioning a Darlington transistor was used on the ECU.

Retrieved from ” https: I had a look in a copy of Towers’ International Transistor Selector, and there’s no mention of it. And darasheet what the pins look from the other side they’re the long metal tabs that come from the case, around the middle of the picture: Email Required, but never shown.

With an “infinite” heatsink, that is: 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 2N is a silicon NPN power transistor intended for general purpose applications. The markings on the case are: KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.

Would someone have information on the device’s characteristics, or a pointer to the datasheet? From Wikipedia, the free encyclopedia. The total power dissipation written P D in most American datasheets, P tot in European ones depends on the heatsink to which the 2N is connected.

I’m trying to find information on a power transistor used on a automotive ECU.

Although the original 2N went into decline relative to epitaxial-base transistors because of high manufacturing costs, the epitaxial-base version continued to be used in both linear amplifiers and switching supplies. This page was last edited on 22 Novemberat Datssheet 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 may result, especially with cases or heatsinks that are not perfectly flat.
