Hi:
I have what it might seem a zener diode. It's marked as E57, but I haven't found any reference that might match my observations.
I've took one from the same circuit and tested isolated with the power supply and a 1k resistor. with 10V, the possible zener stays at 6.6V.
It seems a SOD123 package. It measures (2.6mm x 1.6 mm).
Any idea? it's a 6.6V zener?

I have DRUCK UPS-III-IS Loop Calibrator to repair, and I found one faulty diode (O.L. both ways, even out of the circuit). The SMD code on it is E27 NMC. by ON Semi. I can't find anywhere on the internet what kind of diode it is. Being the calibrator, all elements may be crucial, to be exact, so I really don't want to mess up with any diode there. Especially if it needs to be Shottky or a particular Zener. It is connected between a Poly capacitor and in series with another (different) diode (MX47A) - pictures attached.... -
I need to find a replacement for this diode on one of the six gate drivers of a full-bridge IGBT inverter for a servo motor. It has S3 on the package. How can I find out for sure the right diode that I need. I believe it is schottky because it has 0.2V drop across.
The anode is on pin Ve and cathode on pin DESAT on 316J gate driver IC. Also would be nice if anyone had an idea of the purpose it is serving as it is not included in the suggested schematic of the 316J datasheet.
I have also drawn a partial schematic of the gate driver in this servo amplifier to try... -
I am not sure if this is the right place to post this but I need help identifying a surface mount rectangle diode and all that is printed on it is "DK" it seems to be open so I can't read anything off it. It's in a HP laptop by the power switch. TIA for any help.

Hello guys, i have an old lenovo y700 laptop that has a burned esd diode. I cannot find the Az5123 diode anywhere in my country and I am looking for a replacement or something equivalent if is available. I attach the documentation of the diode and where in the schematic it is needed. If more details are needed I can offer them.Thank you!...
