looking for some mat02 transistors for our ssl 4K.... can't seem to find them anywhere. I have e-mailed recycled audio and am waiting for a response...

pucho812 said:the ones at allied are to-78 and are 8 pin the ssl ones are to-71 6 pin versions.... fwiw I have found an alternative from a company called linear integrated systems. It's part number lm318 from them. It is a direct replacement and can be done in a to-71 package like the SSL one. I am still trying to locate a vendor for that.

No, they're the same size it'll drop right in. The TO-78 is a 6 pin, the MAT02 doesn't come in any other size can, just the 6 pin, and an 8 pin dip as well. Allied doesn't have them anyways though. Double check the specs on the LS318, I was checking them out the other day, for some reason I keep thinking the minimal HFE was lower, but I could be wrong.
I was given conflicting information by people at Analog Devices, but the most recent information is this:
1. The FAB where the MAT02 was made was closed. Therefore, they decided to discontinue the MAT02.
2. Subsequently, there was strong demand for it, so they changed their minds.
3. They decided to redesign the part. I'm not sure if it was because of tooling issues, machinery incompatibilities, newer and better equipment or what, but they decided to redesign the part.
4. The new part will be known as the "MAT12". Samples in March, 2010. Production in June, 2010.

dude I just caught my mistake on the number of pins... :-[
what about just ganging 2 transistors together? after all that is pretty much what the unit is...
ruckus328 said:Dustbro - how many mat02's are on that board though? If there's a couple - that $9 is sounding pretty juicy.

ah so maybe try looking for mat12 as well

If you're looking to buy them though, they're not yet available through any distributors, only direct from AD, at minimal qty 100 @ about $16 each. Woof!
