What is 6J trandito SMD

XHello everyone. Can anyone help me look up SMD components with code 6J as shown in the picture. This smd trandito is in the DAC circuit of the Marantz 6007 CD. Does anyone have the service manual for me, please?

Wow! The discrete configuration of the post-amp of the DAC is wonderful!

However, I have one concern. I believe that AKM's DAC is voltage output. It seems that 2ch is output in para in mono mode. Isn't it possible to connect the two outputs directly in that case? I think you should connect to each through a resistor.
