MP Posted February 15, 2004 Report Share Posted February 15, 2004 Does anyone have a cross reference chart for KT818, KT819 and BD708, BD705 transistors? For example, is there a TIPxx equivalent or 2Nxxxx equivalent that can be used in their place?Thanks,MP Quote Link to comment Share on other sites More sharing options...
MP Posted March 3, 2004 Author Report Share Posted March 3, 2004 I have exhausted my sources for a cross on the above mentioned transistors. Any help would be appreciated....or if anyone knows the specs, I can find something similar from this information.Again, any help would be much appreciated.MP Quote Link to comment Share on other sites More sharing options...
FireFly Posted March 3, 2004 Report Share Posted March 3, 2004 Does this NTE cross reference give you what you want:http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf/$$Search?OpenFormIt comes up with an NTE equivalent for each one you listed and maybe you can get the specs from the NTE part datasheets?Does that help? Sorry if this isn't what you wanted. I'm still learning this stuff. Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted March 3, 2004 Report Share Posted March 3, 2004 Looked for Hours. Here is what I have The BD707 and BD708 are almost the same. the D means Darlington.BD705 TRANS NPN 12A 45V 75W TO220BD708 http://eu.st.com/stonline/books/pdf/docs/4134.pdfhttp://www.st.com/stonline/books/pdf/docs/4134.pdf KT818, KT819 http://elhelp.h1.ru/sprlist/c_tranz.htm When I find more I will post them.

MP Posted March 4, 2004 Author Report Share Posted March 4, 2004 Thanks John.That should get me started. I appreciate the help.MP Quote Link to comment Share on other sites More sharing options...
steven Posted May 3, 2004 Report Share Posted May 3, 2004 :)steven, mp i to had a look through my circiuts on the transisters you described and there missing from the list, if they aint discontinued. i dont know why the info on them aint so freely avaliable, Quote Link to comment Share on other sites More sharing options...
steven Posted May 3, 2004 Report Share Posted May 3, 2004 :)i did some searching on the net well the bd 708 transistor, complimentary silicon power transistor, is produced by s t microelectronics, cant access the data sheetsb the bd705 is what hotwater wizard sys it is as i found the same info . the k818 and k819, theres nothing i can kind on them , Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted May 3, 2004 Report Share Posted May 3, 2004 The Datasheet for BD708 is also on my Datasheet Website. Free membership Required.http://f1.grp.yahoofs.com/v1/ Quote Link to comment Share on other sites More sharing options...

chub2 Posted February 9, 2007 Report Share Posted February 9, 2007 is there any replacement for K818, K819 and BD705, BD708 transistors with commonly available ones ? The mentioned transistors are not available in our place. Quote Link to comment Share on other sites More sharing options...
