Amp repair

My name is Divendra.I am having a hard time figuring a part number for SMD on a Onkyo RZ50.The Code reads :MX but the Power amp board denotes as Q i searched for the SMD it shows as Diode.This transistor is just beside output fet transistors.The output fets are TTA0001 and TTC0001.I am attaching the picture of it.Please any one out there please help me with these.

Hi Divendra,

The code could also read β€œXW”. Onkyo tends to use a lot of Rohm’s excellent discretes, but could not immediately find a good canditate.
I wonder, could you provide a bit better picture (high resolution, natural colors, from above, showing the neighboring comps too)?
