Have been trying to get data sheets online to work out the three pins .

It has the Motorola "M" on plastic TO-220 package.

It is either power transistor, or diac /triac or something else?

Thanks

"Vox"

** All you need is a multimeter with a "diode test" function.

Find the B-E and C-E junctions and you have it nailed as a transistor and you know which is the Base.

The C-E junction has a slightly lower forward voltage than the B-E one.

FAIK - all TO-220 triacs have the same pin out.

"no one"

** Not a TO-220 type - but small signal.
