SGS did the parts, they are SGS/Thompson now (www.st.com)
The 208(D) and some of the other specs are on line on their web page.
Motorola also makes many of these transistors, and their specs are
on their web page (208/208D, 406, 407) They used to make 406D's but
stopped a while ago.
(their data book says the replacement is "MJF16018+diode", thanks..)
