BYY57 / BYY58
35A Silicon Power Rectifier Diode
Part no.
Description
The BYY57/58 are hermetically sealed 35A-
diodes, which are available in different reverse
voltage classes up to 1500V.
The diodes can be delivered with limited forward
voltage
and reverse current differences for
parallel connecting in rectifier stacks and back-
off-diodes
Features
Forward current 35A
Reverse voltage 75V – 1500V
Hermetic press-fit package
Available in different modifications of the
package
Applications
Power supplies
Rectifier diode in car generators
Rectifier bridges/stacks
Back-off-diodes
