Two diodes common cathode
• Excellent thermal performances obtained by the usage of
exposed direct bonded copper substrate
• High surge capability
• Easy mounting on heatsink
ELECTRICAL DESCRIPTION / APPLICATIONS
The VS-VSKCS400/045 Schottky rectifier common cathode
has been optimized for low reverse leakage at high
temperature. The proprietary barrier technology allows for
reliable operation up to 150 °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 AAP Gen 7, 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.
