8A, 100V - 200V Ultrafast Dual Diodes
The BYW51 series devices are low forward voltage drop,
ultra-fast-recovery rectifiers (t
ion-implanted epitaxial construction.
These devices are intended for use as output rectifiers and
fly-wheel diodes in a variety of high-frequency pulse-width-
modulated and switching regulators. Their low stored charge
and attendant fast reverse-recovery behavior minimize elec-
trical noise generation and in many circuits markedly reduce
the turn-on dissipation of the associated power switching
transistors.
