DESCRIPTION
State of the art, ultralow V
F
, soft-switching hyperfast rectifiers
optimized for Discontinuous (Critical) Mode (DCM) Power
Factor Correction (PFC).
The minimized conduction loss, optimized stored charge and
low recovery current minimize the switching losses and
reduce over dissipation in the switching element and
snubbers.
The device is also intended for use as a freewheeling diode
in power supplies and other power switching applications.
