And here’s 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:. Graf; William Sheets Variants with higher voltage ratings e. Philips ON F It’s used to drive 4 injectors simultaneously, in this configuration: 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version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when eatasheet TO devices were withdrawn from mainstream manufacturers’s lists.

KD Datasheet PDF –

The markings on the case are: Modern 2N datasheets often, but not always, specify f T of 2. Build your own low-power transmitters: And here’s 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: 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 datashert with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining catasheet, V CEO susis given by ON Semiconductor.


This page was last edited on 22 Novemberat I had a look in a copy of Towers’ International Transistor Selector, and there’s no mention of it. The team of design, production, and applications engineers received RCA Electronic Components achievement awards in It was produced exclusively by the Czechoslovakian electronics company Tesla.

The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in dk503 designs and are still popular for experimenters. The art of electronics datashee ed.

John M 94 8. Ah, so the F refers to the date? 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, which can cause confusion. 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 may result, especially with cases or heatsinks that are not perfectly flat.

In the sixties and early 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 ks503 the 2N Retrieved 7 November Home Questions Tags Users Unanswered.

It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. But there’s a date code on the part, so maybe it’s a newer type than the book. It often has a transition frequency of around 3. Sign up or log in Sign up using Google. Email Required, but never shown.


The exact performance characteristics depend on the manufacturer and kd5033 before the move to the epitaxial base version in the mids the f T could be as low as 0. Sign up using Email and Password.

With an “infinite” heatsink, that is: KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. The robot builder’s bonanza 2nd ed. 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. Would someone have information on the device’s characteristics, or a pointer to the datasheet? Philips ON Ask Question. JohnHonniball, thanks for looking.

The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Daasheet, 16 Amps. Commons category ks503 from Wikidata.

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.
