Obsolete Flat Based Diode and Thyristor Replacements

GD Rectifiers manufacture a number of flat base conversion kits used to replace obsolete flat based diodes and thyristors. Flat based devices are historically used in rotating applications and can be replaced using either a stud with the thread removed or a capsule combined with a GD Rectifiers clamp solution.

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. Our rectifiers cover a popular range of parts previously made by IXYS, Marconi and Semikron. They are all high voltage and low current, avalanche rated and are suitable to absorb limited reverse voltage transients. GD Rectifiers’ high voltage rectifier units have been designed to handle mains frequency.
