Identifying a component

[passete]

I need help to identify this burned Transistor from a Ryobi battery charger.
Please check the photo, this is the best i can get for the ID.

Thanks

Buddy, if i understand well, i need to replace all of these :
"replace the fet with IRFR5505PBF
replace the diode with BZT55C18
replace the 2 diodes with a single MBR40250G on a customised heatsink with an insulating kit."

Thanks

Re: Identifying a component

probably,
if the fet is bad, you should change the zener diode too.

did you check the 2 mbr5200 diodes for shorts?

No I didn't, how do i check this, testing the 2 poles to ground ?
Anyway, is better to change the 3 components ?
Thanks buddy

Re: Identifying a component

check the resistance between the 2 connections on each diode.
remove them first.
