Where did anyone find 2SJ104 ?
I just ordered 60pcs from HKutsource and all fakes!

I am looking for a source for 2SJ74, 2SJ104, 2SJ108, but I only find a few seller having them for like 11/pc. The cheap ones are always fake!

I measured thickness, they are 3.5mm, much thinner than Toshiba. Should be about 4.0-4.1mm. They have been sanded down and remarked.
I measured RDS, it is around 95 to 115ohms in the 6 I measured, should be 40ohm.
I also measured IDSS and it was around 17mA for the 4 I checked, should be 6-12mA
Also I measured Yfs to be 8-9ms in the same 4, should be 30ms typical.

We should start a thread listing sources with fake and genuine parts.
