Description/Features
The MBR40L15CW 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)
