Features

Fast Recovery time characteristic Eletrically isolated base plate Large creepage distance between terminal Simplified mechanical designs, rapid assembly
Description
This SOT-227 module with FRED rectifier is available into parallel configuration, used for simple parallel rectifier and high current application. The semiconductor in the SOT-227 package is isolated from the copper base plate, allowing for common heatsinks and compact assemblies to be built. That module is intended for general applications such as power supplies, battery chargers, electronic welders, motor control, DC chopper, and inverters.
