how can i make sure i have an original Toshiba 2SK389BL?
In case of power transistors/mosfets i just push them to their upper power limit and see if they can handle it, but in case of low power mosfets?
Thank you guys for the attention.
Re: fake 2SK389?
procedure for Ids matching of Jfets , explained in several Papa's pdfs and numerous threads - is good enough
