Diodes BYY54 User Manual
BYY53 / BYY54
Description
The BYY53/54 are hermetically sealed 25Adiodes, 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 backoff-diodes
Features
Forward current 25A
Reverse voltage 75V – 1500V
Hermetic press-fit package
Available in different modifications of the
package
Applications
