The number is correct but it is a surface mount small block with 3 lines on
lettering with two solder pads ,one on each end . the first line has a logo
ST E,

ST = ST Microelectronics ?

the second line QAJ and the third has C517 . If it is a surge
arrestor ,how do I test them? With an Ohm meter ?

I would think that surge arrestors should test open circuit at normal
voltage levels. I suspect such devices would be near the tip and ring
inputs. Are there two other SAs, ie SA102 and SA103? If so, do they
have recognisable part numbers or logos?

If the devices are indeed surge arrestors, then you could probably
remove them for troubleshooting purposes.

Thanks

I am working on a Panasonic cordless phone (dead). On the main circuit
board in the base unit that are all SMD.
The parts that I need are ID'D by SA101 and SA104(I don't know what
an "SA" is).

Surge Arrestor? Does it have 2 pins?

The number on the part is QAJC517 and is black with no other
marks on it.
Thanks

The "QAJ" looks like a suffix. Are you sure the number is correct?
