DESCRIPTION/APPLICATIONS
This SOT-227 modules with HEXFRED
®
rectifier are in
antiparallel configuration. The antiparallel configuration is
used for simple series rectifier and high voltage 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 HV power supplies, electronic welders, motor control and
inverters.
