ADD-A-PAK Generation VII Power Modules
Thyristor/Diode and Thyristor/Thyristor, 75 A
MECHANICAL DESCRIPTION
The ADD-A-PAK Generation VII, new generation of
ADD-A-PAK module, combines the excellent thermal
performances obtained by the usage of exposed direct
bonded copper substrate, with advanced compact simple
package solution and simplified internal structure with
minimized number of interfaces.
FEATURES
• High voltage
• Industrial standard package
• Low thermal resistance
• UL approved file E78996
• Designed and qualified for industrial level
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
BENEFITS
• Excellent thermal performances obtained by the usage of
exposed direct bonded copper substrate
• Up to 1600 V
• High surge capability
• Easy mounting on heatsink
ELECTRICAL DESCRIPTION
These modules are intended for general purpose high
voltage applications such as high voltage regulated power
supplies, lighting circuits, temperature and motor speed
control circuits, UPS and battery charger.
