Default Lite-On PA-6601-1 - seeking help to identify blown transistor Q307A

Hi,

trying to revive a dead power supply Lite-On 600W TESLAconverter PA-6601-1 manufactured in 2003 and originally used in a PowerMac G5.

Transistor Q307A underneath a heat shield was blown - it was labelled A2700 H403. How do I go about finding a replacement transistor?

Thanks & cheerio, Harry.

uPA2700 N-CH MOSFET.
Trace out the connections to see if it makes senses.
