The 225CNQ 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.
125°C TJ operation (VR < 5V)
Center tap module
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
