Googling for BU102 + TO92 gets nowhere, I
assume as diac in there then triacs

What's inside and how it works:

Returning to that Philips application note
I can only find SOT533 version of BUJ101AU, eg
http://www.datasheetcatalog.org/data...s/BUJ101AU.pdf
a power transistor format rather than TO92 format with 1.5A/3A : 400V/700V
rating , perhaps for this specific use and known peak/av duty cycle then
could be packaged in TO92
