DESCRIPTION / APPLICATIONS
PRODUCT SUMMARY
The dual diode series configuration (VS-HFA70FA120) is
used for output rectification or freewheeling/clamping
operation and high voltage application.

Package
SOT-227
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.
