Features
Description
This SOT-227 modules with FRED rectifier are available in two basic
configurations. They are the antiparallel and the parallel configurations.
The antiparallel configuration (HFA120EA60) is used for simple series
rectifier and high voltage application. The parallel configuration
(HFA120FA60) is 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.
These modules are intended for general applications such as power
supplies, battery chargers, electronic welders, motor control, DC chopper,
and inverters.
