what is that component?

[eng.jaudat]

Hello,
i have SSD Drive suddenly stop working, and there is so important files inside it. i'm trying to fixing the board, measuring the components using multi meter.

but i'm confused about that component. is it a diode? (BE)

i uploaded 3 pictures .

when i negative multi meter cable on negative diode side (if it a diode of course) and positive to positive i hear a buzzer from multi meter with reading on the screen (0.185V) while the multi meter on diode test mode.

if that component is a diode, i think its a bad component, right?

Re: what is that component?

its schematic mark is above it

Re: what is that component?

schematic mark is not clear.
i take a new pic without the component. and attach it again in that reply

The schematic shows it is a diode. If you confuse while checking with digital meter, you can check it with a analog multimeter if you have.

if u confused, remove it and measure outside circuit

It looks like a TVS diode .

It could be a bzx399-c6v8 zener diode?
Or panasonic, DB2J20900L 20v 3 amp schottky barrier diode
It does look like other Nexperia diodes

If it is a zener or tvs diode the anode should go to ground, 0.185V would suggest a schottky diode

Edited because i`m a fool.

TRUE: If it is a zener or tvs diode the anode should go to ground

Re: what is that component?

The anode is connected to the +5 volt power, I would think it is just for reverse polarity protection and is a schottky barrier diode. You should have 5 volts on the anode, connector side and about 5 volts on the cathode. (VCC5) R100 (000) is additional protection
