What do you say to this Transistor die?

weissi · 6th May 2008, 01:13 AM

It's an ISC (inchange semicon) 2SD424 I've got for €0,5 .....

Almost looks good.

They should handle the copper coin with more respect. Nicked up like that they don't work well.

The die looks good sized, too bad they don't rotate it 45° like it should be.

I guess that's a generic high power die, I don't think they make different die's for their very big portfolio.
I bet if I'll order a MJ15003 there will be the same die inside. Too bad I cannot measure the dynamic characteristics...

If one can/will do some testing, I'll be happy to send him/her one for free.

cheers

I thought 2SD424 is original Toshiba and very hard to get. Are you sure it isn't a fake one?

weissi · 6th May 2008, 08:03 PM

Fake Paranoia? I wrote that the brand is ISC, how do you get the feeling that this is a fake?

Maybe Toshiba is faking Chinese parts.

Jacco are you joking?

jacco vermeulen · 6th May 2008, 09:12 PM

That was the idea, yeah.

But as China has been producing these numbers for a long time and maybe longer than Toshiba has not manufactured them anymore, it makes you wonder what is real and what is not.
In 20 years from now the clones will be the genuines and the originals merely antiquities.
