20 A
15 V
600 mA at 100 °C
FEATURES
• 125 °C TJ operation (VR < 5 V)
• Single diode configuration
• Optimized for OR-ing applications
• Ultra low forward voltage drop
• Guard ring for enhanced ruggedness and long term
reliability
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
• Designed and qualified for Q101 level
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.
