Schottky Rectifier, 2 x 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

DESCRIPTION
The center tap 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.
