High Voltage Rectifiers
GD Rectifiers have reverse engineered a range of popular high voltage rectifiers and encapsulated rectifiers for use in applications such as high voltage power supplies, radio and TV transmitters, radar sets, RH heating and electrostatic precipitators.
GD Rectifiers offer a popular range of parts previously made by IXYS, Marconi and Semikron. They are all high voltage and low current and are all avalanche rated and are suitable to absorb limited reverse voltage transients. GD Rectifiers' high voltage rectifier units have been designed to handle mains frequency. Please contact GD Rectifiers should you wish to use any of these in a pulsed or high frequency application.
Modular High Voltage Diodes – J Modules
These are to cover the IXYS UGE range. They are easily bolted together using an Mxx thread and can be used to make a variety of circuits in a small space. Please see the below cross-reference from UGE parts to J-Module parts. These devices operate best when mounted horizontal in airflow or better still, immersed in oil.
| IXYS Part / Vrrm | GD Rectifiers Equivalent |
| UGE 0421 AY4 (4800Vrrm) | J-Ea1650-5 |
| UGE 0221 AY4 (4800Vrrm) | J-Ea1750-4 |
| UGE 1112 AY4 (8000Vrrm) | J-Ea3000-2.5 |
| No IXYS part (16000Vrrm) | J-Ea5000-1.2 |
| UGE 3126 AY4(24000Vrrm) | J-Ea9000-0.7 |

High Voltage Rectifier Modules – HTZ range
Our HTZ range directly replaces the Marconi and IXYS HTZ range. They are form and fit the same and can attach together using a busbar to make single/three phase, half and full wave rectifiers. These devices operate best when mounted horizontal in airflow or immersed in oil.
