operation
• High frequency operation
• Low forward voltage drop
• High purity, high temperature epoxy
encapsulation for enhanced mechanical
strength and moisture resistance
• Guard ring for enhanced ruggedness and long
term reliability
• Compliant to RoHS Directive 2002/95/EC
• Designed and qualified according to JEDEC-JESD47
• Halogen-free according to IEC 61249-2-21 definition
(-N3 only)
DESCRIPTION
The VS-MBR7... Schottky rectifier 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 switching
power supplies, converters, freewheeling diodes, and
reverse battery protection.
