PRODUCT SUMMARY
I
F(AV)
200 A
• Excellent thermal performances obtained by the usage of
exposed direct bonded copper substrate
• High surge capability
• Easy mounting on heatsink
ELECTRICAL DESCRIPTION
The VSKDS409/150 Schottky rectifier doubler module has
been optimized for low reverse leakage at high temperature.
The proprietary barrier technology allows for reliable
operation up to 175 °C junction temperature.
Typical applications are in high current switching power
supplies, plating power supplies, UPS systems, converters,
freewheeling diodes, welding, and reverse battery
protection.
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.
