What is the maximum voltage rating for HVC HVD high voltage diode stacks?

HVC Capacitor's HVD high voltage diode stack product line spans from 5kV through 100kV+ rated reverse voltage, with custom-engineered solutions available up to 200kV for specialized ultra-high-voltage applications requiring extreme voltage handling capability.

|--------------------|-------------|-------------|---------------|---------------------|

Standard HVD	5kV	30kV	10mA – 500mA	General purpose, industrial
High-Voltage HVD-HV	20kV	60kV	10mA – 200mA	X-ray, NDT, scientific instruments
Ultra-High-Voltage HVD-Ultra	50kV	100kV+	10mA – 100mA	Particle accelerators, UHV test equip
Fast Recovery HVD-FR	5kV	30kV	10mA – 300mA	RF plasma, high-frequency inverters
High-Current HVD-HC	5kV	30kV	500mA – 5A	Welding, motor drives, charging circuits
Custom Stacked Networks	10kV	200kV+	Per specification	Research facilities, State Grid labs

Most legacy competitors (including HVCA/Diotec/VMI) cap their standard product offerings at 50kV – 60kV maximum, citing manufacturing complexity and yield limitations at higher voltages.

HVC has successfully broken through this barrier by developing proprietary:

* Graded junction termination structures preventing edge breakdown at extreme fields

* Advanced glass-passivation technology eliminating surface contamination paths

* Multi-chip series-stacking architecture with internal grading capacitors for uniform voltage distribution

This capability enables HVD-Ultra products at 70kV, 85kV, 100kV, and beyond — serving next-generation applications such as:

* Compact linear accelerator modules

* Next-generation CT scanner tubes requiring higher kVp

* Advanced materials processing (plasma-enhanced CVD, ion implantation)

* Spacecraft high-voltage power systems
