DESCRIPTION/APPLICATIONS
The dual diode series configuration VS-HFA140FA120 is
used for output rectification or freewheeling/clamping
operation 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.
