High Voltage Bridge Rectifier Diode Dilemma

I am building a 6kV power supply but I can't find diodes for the bridge rectifier, I have a 6kV, 260mA transformer.
For this transformer I need 10kV diodes but the only ones I could find have the Average Forward Rectified Current of 350mA.
Will these diodes conduct lower currents like 260mA?

Hello,

Yes. The given 350 mA is the maximum current allowed, more will break them.
The 260 mA you stated is within the 350 mA, so they will work.

They will work ok. Please be careful, as you are working with LETHAL voltage and current levels!
 
Check the diode datasheet carefully - sometimes high voltage diodes are designed to work only when encapsulated in serious insulation (silicone sealant is good at HT, but don't use the stuff designed for bathrooms). The diode terminals can flash over if they're left exposed in free air.
