FEATURES

• 125 °C TJ operation (VR < 5 V)

• Center tap module

• 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

• New fully transfer-mold low profile, small footprint, high
current package

• Through-hole versions are currently available for use in
lead (Pb)-free applications (“PbF” suffix)

• Compliant to RoHS directive 2002/95/EC

• Designed and qualified for industrial level

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.
