ONSEMI MBRM120LT3G Schottky Rectifier, 20V 1A, DO-216AA

The ONSEMI MBRM120LT3G is a POWERMITE® surface-mount Schottky Power Rectifier designed for high efficiency in a micro-miniature footprint. It employs the Schottky barrier principle with an advanced barrier metal and epitaxial construction, achieving an optimal balance between a low forward voltage drop and minimal reverse current. This results in superior performance for power-sensitive applications.

Utilising advanced packaging techniques, this rectifier is highly efficient and space-saving, making it perfect for modern, compact electronics. Its unique heat-sink design delivers thermal performance comparable to larger SMA packages while occupying 50% less board area and featuring one of the lowest height profiles in the industry at less than 1.1mm.

Key Features

• Low Forward Voltage (VF): Provides higher system efficiency, which is crucial for extending battery life in portable devices.
• Excellent Thermal Performance: Features low thermal resistance with a direct thermal path from the die to the exposed cathode heat-sink, ensuring effective heat dissipation.
• Robust Qualification: AEC-Q101 qualified and PPAP capable, meeting stringent automotive and industrial reliability standards.
• High Safety Rating: The moulded epoxy case carries a UL94V-0 flammability rating.
• Compact Design: Its exceptionally small size makes it the ideal choice for portable, battery-powered products, and densely packed PCBs.

Typical Applications

This versatile rectifier is commonly used in AC-DC and DC-DC converters, reverse battery protection circuits, and for O-ring isolation of multiple supply voltages. It is suitable for any application where a combination of high performance, efficiency, and minimal size is critical, including power management systems in automotive and industrial environments.
