ADATA SU750 - Need Help Identifying Component
Posted: November 21st, 2023, 13:36
Hello. I am trying to recover the data from a ADATA SU750 SATA SSD. The drive suddenly stopped being detected by the computer both in BIOS as well as in the OS. I have tried using different computers, different adapters (such as a SATA to USB3 adapter, external SSD/HDD 2.5/3.5 dock, etc) and it behaves the same way.
I removed the PCB and began with a visual inspection. Everything looked normal. I then began probing capacitors and inductors for shorts and found none. I then took a look at the PCB through a thermal camera while it was connected to SATA to USB3 adapter and this component showed up as getting quite hot. It looks like the component marking reads "qHEJD". I tried doing some searching for this component, but was unable to find it. In my research, it appears to be some sort of voltage regulator or perhaps a step-down converter or some other type of switch. Not really sure.
There is an identical component next to it with a similar circuit and the component in question has a different voltage reading on pin #3 compared to the identical component next to it that doesn't appear to get hot. This leads me to believe the one that is getting hot and has a different voltage reading is bad and needs to be replaced.
I was hoping I could find just the component and order it rather than buy an identical new SSD to steal the component from. Hopefully someone here can help. If you need more information or pictures or voltage readings, etc. please let me know and I will get them right away. Attached is a picture of the component in question.
Thank you!
