PFR 850S → 856S
FAST RECOVERY RECTIFIER DIODES
PRELIMINARY DATASHEET
LOW FORWARD VOLTAGE DROP
HIGH SURGE CURRENT CAPABILITY
APPLICATIONS
AC-DC POWER SUPPLIES AND CONVER-
TERS
FREE WHEELING DIODES, etc.
DESCRIPTION
Their high efficiency and high reliability combined
with small size and low cost make these fast reco-
very rectifier diodes very attractive components for
many demanding applications.
