BYY57A / BYY58A
50A Silicon Power Rectifier Diode
Part no.
Description
The BYY57A/58A are hermetically sealed 50A-
diodes, which are available in different reverse
voltage classes up to 800V.
The diodes can be delivered with limited forward
voltage
and reverse current differences for
parallel connecting in rectifier stacks and back-
off-diodes
