> I would prefer to start with a "normal" transistor and see if the results > are acceptable for my use I wonder - if you got a metal can, eg TO18, and took the top off, (like we used to do to make an opto-transistor) that would expose the silicon. Not something to consider for production but thought it would be an interesting experiment to test thermal response _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
