I am staying with relatives near Florence. I am planning to visit Florence, Pisa, Siena, Venice, Rome... and let's see how much time we have left afterwards.

Availability of 10m45S is not a problem per se but Ixys products we look for are not usually shipped to Europe. The 10m45s and higher voltage sibling is one of them.

Shipping charges are a killer. As high as 18 eur-22 eur from some internet shops!

Happy to hear you are visiting "il bel paese" Just beware of the heat. In Florence we just reached astonishingly high temperatures and humidity levels. Luckily I live in Milan and the weather is bearable.

You are 100% correct. The document I linked to shows all the possibile solutions for CCS use. Some are limited to low voltages some are not. The supertex DN2540 is a widely used alternative to IXYS. I used both in the same circuit and both work very well. Obviously the resistor values to set the current draw are different, but all in all the two devices are very similar (at least from my point of view )

The document I attatched is really informative, all the main topologies are covered with good detail and are very well explained (at least for someone with limite knowledge like myself)

Digikey Italia has it in stock, but more expensive

Check on the IXYS site for more options.

I sent an email to future electronics: minimum order 700 pcs

Priority Mail "flat rate envelope" from the US to Europe increased to $16.95 a few months ago, and express mail is now $36. With the cost of packing materials and time engaged in filling out customs forms, the charges would seem reasonable.

Digi-Key sells IXYS fets.

just placed order with Digi-key from NZ, last time I tried "not available for shipping to your country" message, not this time, so I'll see if they actually ship - aadvarkash, PM me if you want a few

Yep. $20 seems like a lot to ship a small part, but that's what the postal service charges... If you want slower service, I think first class mail is still available, but then you have to pay someone to stand in line at the post office.

I think a bigger issue with the IXYS parts is that they're marked as obsolete on IXYS' website. At least they were last I checked.

Of course, there are other options - including implementing discrete bipolar current sources. Or... circuits like the LT3092. That could be fitted with a cascode and make a killer current source. I soldered one up last night and need to go measure its performance.

10M35S is obsolete, 10M45S and 10M90S are 'active part'.

I bought IXTP08N50D2 ( 500 V / 800 mA) and IXTP08N100D2 ( 1000 V / 800 mA ).
Both types are in TO220 case.
