Anybody here can please help me to identify this zener diode? It would be very helpful if anybody can provide the datasheet for this zener. I would like to buy this zener diode but unfortunately i cant found the datasheet. Thank you very much!
Actually I cant proceed buying it because i cant found the datasheet for this component so i cant identify the correct specification for this component. So if you could help me identify this component, it would be great! then i can proceed on sourcing for this component or try an alternative components. thanks for your message anyways..
Thanks for your msg. I assume its zener base on this website **broken link removed**
Actually I cannot Power up the Unit and test the zener voltage.
1. Zener was shorted already.
2. Main unit unable to power up because it needs the interlock from the plc. So we need to install inside the machine before we can test for power up.
Is theres any other way to determine the specs of this zener by the body marking only or maybe anyone can recognize the brand of this zener (the pyramid like logo).
Thanks for your time.
Thanks FvM. Maybe I can start with this reference to search for the datasheet for this z-diode. I just need the datasheet so I can find alternative for this component if ever it is totally obsolete in the market.
Actually I can't power up the PSU unit because it is somehow needed the PLC for interlock. But while troubleshooting offline. I found this component (zener diode) was shorted. I already isolate and remove it from pcb but still short 0.091Vdc (by diodecheck).

OK Diodes often fail in SC mode from over stress.
If 5mm LEDS are avail. Try those. If too bright, use more in // or get a bigger LED...short Lead time compared to the diode replacement ... for debug purposes. Epcos is not in the diode biz but Panasonic branch may have. Looks like a 12 wk leadtime part.
Not a safe assumption I'm afraid. It is one of the most commonly used glass constructions for glass diodes of all kinds and as FvM mentioned, some temperature sensors too.
A DVM 'diode' test simply shows the voltage drop across the junction at a particular current, that current isn't even standardized across different DVM models. I assume your test is with the device out of circuit, do you get a different reading if the device is reversed?
Almost certainly it is a diode of some kind but other than the part number there is little to distinguish them if faulty.
Is it possible to post a photograph of the board it was removed from? It might give clues to it's function.
