Hello is there a good web site for identifying surface mount transistors
i did find an old site www.sos.sk/pdf/sm_catalog.pdf
and diodes.com
i attached photo of this transistor small t 23
measures like PNP with resister on base

Trouble is there is no complete consensus on these markings and there are duplications so you need to consider the style of the markings and double-check with the spec. sheet of the manufacturer (usually the last sheet before the performance graphs).
If you can use an Atlas semiconductor tester (fun with smt!) it will identify the nature of the component IF it is still what it should be - blown FETs test as a diode junction normally.
Then head to the web until you get consistent answers - the silk-screen legend can help after all a D102 is not likely to be a transistor (you hope) but a Q102 or TR102 will!
Certainly looks to be a PDTA123JT as anniel747 suggests.
