Dynex IGBT Modules and FRDs by GD Rectifiers

FRD Modules

Dynex's FRD modules regulat electricity flow to ensure higher reliability and increased efficienfy in motor drives and other variable speed processes. Dynex's new fast recovery diode module range includes single and dual diodes rated at both 1.8kV and 3.3kV.

The 1.8kV variants include single diodes in an L footprint package (106 x 62mm) with ratings of 300A and 600A, and dual diodes in an F footprint package (130 x 140mm) with ratings of 600A, 900A and 1200A per diode. The 3.3kV variants include single diodes on the L footprint (62 x 106mm) and P footprint (140 x 73mm), both with ratings of 400A, or dual diodes on an N footprint (130 x 140mm) with ratings of 400A, 800A and 1200A per diode.

High Power IGBT Modules 

Dynex utilise superior power cycling with the latest IGBT generation die with minimised switching losses. The low inductance power busbar design enables the module to cope with fast switching transients such as those generated by next generation trench gate lGBTs and Silicon MOSFETs.

The Dynex manufacturing plant offers device design, wafer fab, packaging, qualification and a testing service available on site.
