The UK based company Profusion sells there own brand of lateral mosfets (Exicon) and has equivalents for the 2SK135 and 2SJ50:

I have deal with Profusion in the past for small numbers and I can not recommend them highly enough.

Hi Marvellous

I asked a similar question some time ago. The Exicon parts seem to be about the closest youll get.

http://www.profusionplc.com/hitachi.htm

No idea where to get these in SA. I have tried without success.

One could always replace them with something significantly better, as the 2SK135 and 2SJ50 are pretty old. I dont remember if IR makes a IRFP240/9240 equivalent in a metal can package.

Any suggestions out there???

Cheers, Stuart

RS components still stock the 2SK135 and 2SJ50 although these are not made by Hitachi anymore. Hope this helps.

Hi diyman

Thanks. Didnt realise RS would have them. I dont tend to use RS as here in SA they are HMMMMM expensive.

Those are not TO3 but fits if it's not too tight. The electrical properties are similar but not exact. The threshold voltage is higher for instance. In many places you can use them but in some designs you have to adjust a little, especially the bias arrangements.

I don't understand what you mean?:scratch:
do you mean they will work but will not give same power?
or they will work but wont get same quality?
or they might not work at all?

peranders got your email Thax!
