Need help with burnt transistor on prolux lipo charger

Hi

My 2 years old son took the lipo charger
and pluged it into 220V... (He is fine..)

One transistor burnt and the charger is not functioning anymore...
I have managed to find it (marked red on the picture,near the
12V input wires)

Can anyone help me with specification of this kind of transisor?
I was thinking to take it to some electronics shop and by a new
transistor...


Any advise will be very helpfull,
Daniel

There should be some tiny white letters on the top of the black transistor. Take that number to the local electronics shop, and you will find your replacement.

HOWEVER, you should know it's never as easy as replacing a single transistor!

Thanks for your answers ...

I have managed to read "1AM" writen on the transistor back.
My local electronics shop told me that he needs real catalog No

I have manage to locate this kind of transistor on my of my old
56K Fax-modem PCB.
do you think I can use it?

Steve,
another question,
I have tried to find catalog No for another transistor
(This one is "2AM")

How do you use the serach option to find it?
I have searched for "2AM" and found nothing.
