Rectifier diodes
ultrafast, rugged
GENERAL DESCRIPTION
Glass passivated high efficiency
rugged dual rectifier diodes in a
plastic envelope suitable for surface
mounting, featuring low forward
voltage drop, ultra-fast recovery
times
and
soft
recovery
characteristic. These devices can
withstand reverse voltage transients
and have guaranteed reverse surge
and ESD capability. They are
intended for use in switched mode
power supplies and high frequency
circuits in general where low
conduction and switching losses are
essential.
