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
NST120F60-A is used for simple series rectifier and high
voltage application. The parallel configuration NST120F60 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.
