Diode Division. High Power Diodes for Rotating. Application overview

Vishay Semiconductor supplies since more than 35 years several Diode part numbers suitable for High Speed Rotating Application.
The diodes are manufactured using dedicated materials and standard process flow and then are submitted to dedicated test sequence to meet customer specification.
Four major product families of Discrete High Power Product families are involved :
STUD DO5 (for Ifavg 40-90 A)
STUD DO9 (for Ifavg 300 A)
STUD B8 (for Ifavg > 300A)
Power discs (hockey-puk) for Ifavg > 500 A
In all diode families we recommend to mount diode package in order to have centrifuge force axial to device body.

Diodes for Rotating application are hermetic devices designed to survive at severe mechanical and environmental working conditions.
Typically MIL-STD are used as guideline for Thermal Shock, Vibration, HTRB, Temperature Cycling, Centrifuge, Power Cycling tests.
Typical application were used are:
Alternators
Power Generators
Converters
