Default Zenith PV4657BG SMPS tran. question

Does anyone know if the SMPS switcher transistor on this unit has a
built in damper diode or not? This is not the HOT, but the low
voltage supply switcher. Sorry I can't give the original number, but
it is not legible.

If it's location QX3407 your referring to , yes it's a FET with a damper
diode.
