FRD Modules

Power control through innovation FDR Modules

Fast Recovery Diode Modules (FRD)
We have segmented our FRD module family into groups defined by maximum working voltage. Each group includes the different circuit configurations presently available at that voltage. Other configurations and ratings not listed below may be available in our standard outlines upon request. We are also happy to offer naked die or custom FRD module solutions to customers with non-standard requirements.
