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.
