Ixys IXCP10M45s IC

I have had these chips on back order from DigiKey since last year! I have received dozens of emails asking where to get them. None in stock anywhere. I got an email from DigiKey today stating that my back order has shipped. DigiKey has 5825 in stock as of this moment. Last time they had these in stock (November) they were gone in two weeks. If you need these, get some now.

Thanks for the notice! I'll make sure I buy some tonight. I'm getting annoyed by Digikey's lack of stock as well!

I'm not sure if there chips or high voltage J-Fets, do you know? Anyhow, thanks for the heads up, I have some projects coming up intended to use them.

Thanks for reporting that Tubelab!

What about a group buy for European people? I am in for 20 pieces.

It's not just DigiKey. No one seems able to get these things. IXYS's own web site has a stock locator, which doesn't seem to show any stock at any of the major distributors for any of their useful (to tubeheads) high voltage chips or fets. I sent them at least 2 emails asking how to get small (100 to 500 pieces) of their products, and never got a reply. I guess they have enough big customers to be able to ignore everyone else.

The following article implies that the device is a complete chip:
http://ixdev.ixys.com/DataSheet/88ed...4e89b3323c.pdf

There was a paper on the IXYS web site explaining the use and application of this device. It also stated that the device is a complete circuit. That paper (called IXC.pdf) is no longer found on the IXYS web site, but can be found here:
http://www.datasheet4u.com/html/I/X/...ation.pdf.html

I have seen other information that claims that the device is nothing more than a specially doped depletion mode mosfet. This article states that the device is a mosfet, and even implies that it can be replaced by a DN2540 by changing the resistor value. I have not tried this yet.

What's inside? I don't know. I have tried to cut the top off of the ones that I have freid, but always destroy the die in the process.

I'm also interested in a very small quantity (say10-20). The freight cost from Digikey to New Zealand is a killer....$67USD for UPS.

Anyone in New Zealand interested in a group buy or, is anyone happy to on-sell to me?

Cheers

You can request USPS shipping from Digikey. Prior to the recent USPS increases I was getting shipments from Digikey for around $25-40 USD via air mail. If you order, say, $100 worth of parts and compare Farnell and RS prices for similar you're still far ahead. Not worth it for a small order, but who couldn't use more Panasonic caps?

DN2540

In the newest issue of AudioXpress they get better results with a DN2540.And DN2540 and a LM317.

'Better' being a relative term in the case of coupled to an LM317. As per Figure 13D, noise is about 118 dB down vs. 117 dB above 15 kHz. I can live with the compromise.
