J
operation
• High purity, high temperature epoxy
encapsulation for enhanced mechanical
strength and moisture resistance
• Very low forward voltage drop
• High frequency operation
• 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-40L...CW... center tap Schottky rectifier has been
optimized for very low forward voltage drop with moderate
leakage. The proprietary barrier technology allows for
reliable operation up to 150 °C junction temperature. Typical
applications are in parallel switching power supplies.
