High Voltage Diodes

GD Rectifiers offers a wide range of High Voltage Diodes which are 100% hermetically-sealed within a ceramic tube for reliability. The units feature avalanche technology, axial-lead mounting and high voltage characteristics. The diodes are for use up to 180kV and can be mounted in oil or air.

These units are compatible with solder and screw connectors and are used in applications such as high voltage power supplies, measuring equipment, x-ray equipment, electrostatic precipitators, electronic beam welding, lasers and cable test equipment.

These high voltage diodes have an m5 screw for mounting at either end and can be easily replaced when required.
