Default 2sk170bl, any interest?

Mouser has the toshiba 2sk170bl in stock.

At 1000units it costs 0.48$ per unit. If we get 10 people @ 100 units per person this would be quite easy to accomplish.

Please let me know if anyone has interest in this.

Ask Mouser for a warranty.
And check a few/many before you start distributing around the world.

They confirmed already that they are in stock, and I would assume that mouser being a reputable company did buy directly from toshiba and that these a not fakes.

Shipping would be free from mouser to me and then A padded envelope and shipping should go for about 5 or 6$

You should order a handful first and determine if they are genuine or not. IF they have a "W" or "M" in the little circle on the curved part of the plastic pak then i would be extremely cautious. Also look out for laser cut part numbers and the 200 pak being blue and saying Malaysia or Thailand.

I just bought a quantity from various Asian suppliers and found that the alleged 2SJ74BL did not look like my NOS 2SJ74 on the curve tracer by any stretch of the imagination.

The alleged 2SK170BL, some of which came from a reputable US source as well, has the same physical appearances as described BUT looked good on the curve tracer. This does not mean that they are real 2SK170 Toshibas.

I have no good way to measure the NF, and that would perhaps be definitive. It was suggested to measure the Rds ON, but I have not done that.

The Idss group did match, fwiw, on both devices.

Left most pic is asian sourced 2SJ74
Right pic is NOS Toshiba.

SAME settings on tracer...

Maybe I'm being naive, but would mouser really buy transistors from a doubtful source?

I don't have any means for testing them so thoroughly so I couldn't provide any assurance that they are genuine. Maybe this is much more troublesome than I thought...
