Hi,

Hitachi has HV diodes up to 14kV
<http://www.pi.hitachi.co.jp/pse/product/diodes/2006316_14592.html>
I have successfully replaced the now obsolete BY8410 with DHM3J120.

VMI has up to 20kV
<http://www.voltagemultipliers.com/html/selection_guide_hv_diodes.html>

HVAC is another possibility with diodes up to 30kV.
