8A, 100V - 200V Ultrafast Dual Diodes
The BYW51 series devices are low forward voltage drop,
ultra-fast-recovery rectifiers (t
RR
< 35ns). They use a planar
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.
Features
• Ultra Fast Recovery Time (<35ns)
• Low Forward Voltage
• Low Thermal Resistance
• Planar Design
• Wire-Bonded Construction
Applications
• General Purpose
• Power Switching Circuits to 100kHz
• Full-Wave Rectification
