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.
