Default Looking for complementary NPN-PNP pair

I am trying to find replacement parts for this 300V complementary medium power NPN/PNP transistor array (for temperature tracking)
which appears to now be obsolete...

http://www.zetex.com/3.0/pdf/ZDT6757.pdf

There are quite a few 160V pairs, but I am looking for at least a 200V part. Does anyone know of another part out there ?? Both in one package is necessary for temperature tracking/cancellation for a current source running up to 160 or so Volts so 160V parts are on the edge.

Thanks,
boB Gudgel

do not think there are many
not even 200 Volt in one package

using 2 separate Transistors and glue them tight together would be my way

regards
