Carey - There are numerous parts that have low thermal sensitivity - even at the short durations experienced in Wave and reflow soldering. Occassionally SOT-23s show up but generally speaking, these components are robust. Perhaps you can at least get a max. temp. spec. out of H-P. Don't waste your time with the salesman or distributor. Go to someone in Applications or Product Management for that group. One key question - just how high a temp is the component seeing? Have you attached at thermo-couple to the part and profiled it?
