Hello all my friends,
I hope all of you are doing well.
I have a rectifier ElTEK and I found this SMD component (WAW) I searched on the Marking SMD site and I didn't find what is this to test it well.
Kindly anyone know what is this, Thanks for all your support my friends.
And my best regards to all of you, thanks in advance.

R3117N273A
The R3117Nxx3 is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low
supply current, which can be operated at an extremely low voltage and is used for system reset as an example.
The IC consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output
driver a nd a hy s teres is c ircuit. The det ec tor t hres ho ld i s fixed with h igh acc ur acy i nter na lly an d does not r eq u ire
any adjustment.....
