Anyone successfully use Microwave Oven HV diodes for a Scope voltage multiplier?

[Not_Sure]

Hello,
I am wondering if the very inexpensive CL01-12 type Microwave oven HV Diode would be suitable to use in a DIY voltage multiplier for a Tek 465.  I have been unable to get any information on the TRR of this type of diode as the datasheets don't spec it or leave a value out.  I assume its either not tested, or very slow, maybe both but searching has revealed nothing about this class of HV diodes.

Thanks,

Not

The diodes used in Panasonic MW inverters are likely to be faster. They operate at up to about 40Khz.

Not cheap though, https://www.wagneronline.com.au/panasonic-stack-diode/microwave-parts/service-repair-parts/ux-c2b-3644/960833/pd/
I tested one here. It takes 60ns to recover from 20ma forward bias.
Years ago I used much smaller diodes to build a split winding flyback EHT supply for a BWD oscilloscope. They were about 1cm long and pointed at one end. I think they were for small black and white TVs.

Check Ebay or Amazon or AliExpress.  From China they are ~$1/ea.  In the states its more like $1.50 if you look around and buy in 5 or 10 each lots.

350mA diodes are way overkill.
For a scope you don't need over 5mA, typically a 2CL73 is used as an example. 5mA 12kV 100ns but get the longer 17mm parts if you are not potting the whole thing. Lots of 10mm sized parts for cheap on Ali or eBay.

Panasonic Inverter microwave I took apart used Sanken UX-F5B pretty big 350mA at 8kV PIV 150ns fast-recovery. A bit low on PIV I think.
