Default 2sk1058 availability?

I am trying to find new 2sk1058 mosfets. Are these still made or should i just try the Exicon parts?

Tayda electronics? says online they have the 2sk1058 in stock. anyone heard or ordered from these guys before?

or.. is there a currently made lateral mosfet that is better or equivalent to these?

Thanks!

2SK1056 ~ 2SK1058 series is long discontinued, but still obtainable. For example, MCM Electronics still carries stock of them.

The replacements are 2SK2220 (180V, 8A) and 2SK2221 (200V, 8A). Their complements are 2SJ351 and 2SJ352. These are in TO-3p mold package and made by Renesas, a spin-off from Hitachi. Renesas claims these are "improved" version but the capacitance here and there increased from the original (2SK133~135 series and 2SK1056~1058 are practically the same except for the packaging).

Have fun!

I bought quite a few 2SK1058 for my Optimos build.

I eventually found them for sale (in the UK) from Cricklewood electronics.

Cricklewood Electronics CCTV and Electronic Components

Alternatively there are quite a few sellers of 2SK1058 on eBay. I have heard of some counterfeit product so some caution advised. Good feedback rating should be a safe bet i reckon.

MCM is the way to if you in the states, has anyone here used the alfets??? At their pricing having them shipped to the USA might be cheaper than the MCM alternative.

They are still active parts, I placed a purchase order to renesas in Feb 2010 and is about to receive them.
If you buy this pair in sufficient quantity, their price is about twice of irfp240/9240, which I think is very reasonable.

And Renesas is a joint venture of Hitachi and Mitsubishi, with NEC also joint in at April fool day this year.

JUst for a simulated of course.
I am not in reality ...

At tis scheme, is the vGS versus idle 100 mA reasonable?
Think mabe the voltage is a bit low from real value ...
