Schottky Rectifier, 20 A
FEATURES
• 125 °C TJ operation (VR < 5 V)
• Optimized for OR-ing applications
• Ultra low forward voltage drop
• High frequency operation
• Guard ring for enhanced ruggedness and long
term reliability
• High purity, high temperature epoxy
encapsulation for enhanced mechanical
strength and moisture resistance
• Compliant to RoHS Directive 2002/95/EC
• Designed and qualified according to JEDEC-JESD47
• Halogen-free according to IEC 61249-2-21 definition

DESCRIPTION
The Schottky rectifier module has been optimized for ultra
low forward voltage drop specifically for the OR-ing of
parallel power supplies. The proprietary barrier technology
allows for reliable operation up to 125 °C junction
temperature. Typical applications are in parallel switching
power supplies, converters, reverse battery protection, and
redundant power subsystems.
