Firstly thanks for your reply .
And Sorry Hero ... that is my mistake
The Correct Parts Number is STP2N60FI
And yes you are right - Input Fusing Resistor (1.5 ohms) and Choke have blown out for damaging the MOSFET . I have checked the other parts - Resistor, Electrolytic & Mylar, Silicon & Crystal Diode , C1815 transistor and Chopper are OK .
A new adapter Cost is 400 Rupees and MOSFET cost is 35 Rupees . So, I am thinking to repair the adapter .
I am attaching the PDF File of STP2N60FI
below . Please have a look and plz tell me will it be OK ?
Thanks Hero for your reply .
