Need more info on a ST "PK030S" device

[japlytic]

I am after some information on a ST "PK030S" device; unsure if it is a MOSFET or bipolar transistor, or even an IGBT or SCR.
Any further information would be greatly appreciated.

well I shook the google tree and nothing fell out that was of any use...

I tried a few variations etc, still no pdf's of use fell out all I found was stuff like this...

searched ST as well, could not find a reference to what it might be

stuff all help I know, sorry Japlytic..... hope someone can ID it for you

The package is a TOP-3PF, confirmed by

My tests with the "diode" function of a multimeter yielded these results (junction drop):
+ on Base, - on Collector: 0.493V
+ on Base, - on Emitter: 0.553V
+ on Collector, - on Base: infinite
+ on Collector, - on Emitter: infinite
+ on Emitter, - on Base: 0.555V
+ on Emitter, - on Collector: 0.751V

This device is a bipolar transistor (not a Darlington) with a damper diode between Collector and Emitter (confirmed by the 0.751V junction drop)
