Ian,
"What's so bad about their track record that anyone would naively label them as shockingly bad business?" I don't think that this was meant as a reflection on the devices themselves but rather a comment on the viability of producing products that have a very limited market.

They are laterals, not VFETs, and technically they are not extinct, I have 6 living pairs

Yeah, but this is the first time that major distributor's sites are saying "No longer manufactured".
Never ceases to amaze me how eager people are to believe what they are told without stopping to question why they are being told it

Hi,
The 2SK135/2SJ50 are lateral MOSFETs (sometimes called DMOSFET) and no VMOS FETs. A VMOSFET of the early days was the SILICONIX VN66AF. Actual produced MOSFETs like the 2SK1056/7/8 and 2SJ160/1/2 are based on the same technology as the 2SK135/2SJ50.

Are Renesas the manufacturers of the Lateral mosFET wafers/dies?
or are they simply packaging them just as many other do?
Is there a second factory producing Lateral mosFETS, or are they all still coming from that one rebuilt factory in Japan?

I'm deeply embarrassed about having you overlooked, Scotty 😛!
And now, what about your SK135/SJ50 pairs? Still on your way of getting a breeder 🙄?
Best regards!

Does anyone know, for what date End of Lifetime for the lateral Mosfet from Renesas is scheduled?
Profusion still seem to be promoting the Exicon branded Lateral Mosfets.
The available range seems to have been rationalised, only 200 volt parts are available, and the Alfet branded parts are discontinued, but substitution parts are listed here...

The branding of these products has always been confusing when so many parts were allegedly the exact same component so this makes sense to me.

The Profusion Exicon parts are still showing as active on their website. Using 12 of them here, even sold off the spare ones, so hope they are indeed still available for many years in case I do something stupid with my 6-channel amp!
Aren't they more or less drop-in replacement for the Renesas parts anyhow? Maybe some tweaking of gate capacitance is needed but I think we can largely get by with only the Profusion parts.
