2D42 blown resistor plus smd component search

nrbrt

Hi,
I have been stupid enough to stick my leads to 230VAC contacts after measuring some mA signal and I forgot to switch the leads back to the right position and POOF (and flash)! Broken oscilloscope.


I am looking for the small SMD component next to the darker blue resistor (150 Ohm?) That resistor appears to be blown and the smd component looks like it exploded.
Can anyone help me and tell me what I need to replace them with? I have access to a hot-air soldering station and I have already removed both components. An electrical schematic drawing would be nice too :-)

Thanks in advance!
