Matched PNP/NPN dual transistors

Thanks Dale, for outlining what characteristics are important and providing a little more depth to this term, "matched."

According to its datasheet, the STD845DN40 is intended for use in fluorescent lights.

Thanks for the heads up, ingenieus. Yes, I realized that they intended use was far from audio applications, but I figured I'd bring it up as I knew of no other currently produced dual transistor components. After reading through the datasheet for the THAT devices, they seem much more suitable for my intended use.

THAT 3XX series matched arrays are large geometry die devices. The dies are made individually and then matched, and placed in the same pakage. They typically measure DC Hfe ~90. They are very good for input stages and can be cascode for higher voltage operation. I have used them and they work very well but they are a bit pricey.
