A Google search for smd w70 gives it immediately
The OP asked if it was a bzx84-A11, and the code W70 denotes (at least in one usage) a BZX84-B16. I thought there was enough evidence.That depends on the manufacturer though. W70 from Panasonic, for example, could be completely different from W70 from Diodes Inc.

In place of the 10K resistor use these resistor values (or approximate values) in turn:I cannot determine for sure about the manufacture, but i can confirm it's a diode, but here's what makes me confuse, if this is an nxp diode, and according to nxp bzx84, then the working range for this series would be from 2.4 to 75v related to marking code, in this picture, the marking code is 04 instead of the w70, and nxp datasheet, 04 would be an 11 volt zener, so it is bzx84-a11, but if i feed this diode with 24v series with 10k resistor, the voltage measured is 16 volt, i compare it with other w70 with marking code is 10, the result is the same, 16 volt. any advise would be appreciated, thanks a lot
No probs JS,yes, the voltage across the diode is around 16v, means this is BZX84-B16, thanks a lot all for the help
