What component ?

[bianchi77]

Everyone,

What component is that ?
I see it near inductor on 320Gb HDD board from Seagate
Is it blown capacitor or TVS diode ?

Cheers

Re: What component ?

i suspect from the track layout etc that it's some type of resonator.

it's not power related.

Re: What component ?

resonator on HDD...what's that for ? I can't see the name / label of the component ?? what's the type ?

Re: What component ?

some kind a crystal oscilator ??

Re: What component ?

exactly, it's a timing reference probably - for one of the other chips.

Re: What component ?

so if it's broken because of voltage spike...could it be all my TVS are died and the zener as well ?....I tested in circuit with analog multimeter...all the TVS gave me a value on reverse and forward....

Re: What component ?

you cant test them on the board, you wont know if it's the tvs or something else connected with it.

Re: What component ?

so I must unsolder those TVS and test it off board....similar character with diode ?

Is this related to this thread? https://www.badcaps.net/forum/showth...301#post694301

Re: What component ?

I tried finding datasheet for these components code :
ON 307 15A and FT 301 LE....looks like a diode but I'm not sure if it's transient voltage suppresor diode ??

Re: What component ?

ON = ON-Semiconductor.
307 is a date code
15A = 15v TVS diode

Re: What component ?

and FT 301 LE ? so the code = 15A and the other one is LE ?

[bianchi77]

Re: What component ?

FT 301 LE = https://cdn.badcaps-static.com/pdfs/...a3083c9422.pdf, correct me if I'm wrong ?

[stj]

Re: What component ?

LE is a 12v tvs diode

How do you get the info ? thanks

Thanks for the info, how do you know if it's faulty ?
