Data Sheet K818, K819 and BD705, BD708

[MP1]

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

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.

Does this NTE cross reference give you what you want:

http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf/$$Search?OpenForm

It 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.

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 TO220

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,

 

[steven2]

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 ,

The Datasheet for BD708 is also on my Datasheet Website. Free membership Required.

Found some schematics that use them as well.

is there any replacement for K818, K819 and BD705, BD708 transistors with commonly available ones ? The mentioned transistors are not available in our place.
