The corrent aggregation is being processed. You can still post your order below to take part in the next aggregation.

I am sorting the active orders now, will ship Oct. 9.

Technix,

Does the factory produce any other votlage rating buried zeners? Say for example 8.2V or 9.1V buried zener on its own?

I don't think so. At least it is not shown on their catalog they gave me.

For use as a precision reference, only a very limited voltage range is good: either about 5.5 V used as a zener only or something like 6-6.4 V to be used in combination with an PN junction.

Lower voltages would have to much TC and too much differential resistance and would thus need very stable resistors / current source. Higher voltage ones are usually too noisy. The low noise of the 2DW232 might be due to the slightly lower voltage, than otherwise typical for compensated zeners.

In theory one might use two zeners and one diode in series to get something like 11 V - but I have not seen that as a single unit.

Kleinstein,

Good information, well understood.

Reason behind the question is the temperature coefficient of a single diode, It is marginally too low for my needs.
I underline single diode not a combination of zener and forward junction.

Technix,

Please ask the factory whether they have a slightl;y higher voltage zener diode in buried structure device.

Posted. It should arrive some time soon.

Mine arrived at 25th of October. Well packaged!

Thank you very much technix for all your efforts. Very appreciated.

Andreas

I received the diodes today. Thank you very much, technix!

I now just need to wait for the PCBs to arrive and then I can start tinkering around with them.

I received the 2DW232's about 4 weeks shipping time. Thanks to technix for this service.

I have some from Ali with Seven packaging and date/lot code "15-4", but these have no extra markings.
The can looks similar, stamped a bit wonky so I'm not sure what plant made them.

After two months of waiting (usual time for Italian customs $:=\$ ) I received my zener too.
I will try them soon

.
Many thanks to technix for its support

Hi Technix -- are you still offering the 2DW23x diode aggregated offers? If so, I'd like to get some.

Thanks!

John

The aggregation is open, but this order might have to wait a while since there is nobody in the waiting list. You should PM me your address and I would replay the PM with my payment information. I can accept bank transfer and PayPal.

Octane · « **Reply #118 on:** May 30, 2018, 12:33:16 pm »

Hi technix,

Im not in a hurry! Thanks for making this possible!
If not enough people aggregate, no big deal either.
PM will follow today.

Thanks,
Michael
