Overview
The RB731XNTR is a Schottky barrier diode array manufactured by Rohm Semiconductor. It features a triple line configuration housed in a UMD6 surface-mount package, also identified as SOT-457 or SC-74. The device supports a maximum repetitive reverse voltage of 40V and an average rectified forward current of 30mA. Key electrical parameters include a maximum forward voltage of 0.37V at 1mA and a maximum reverse current of 1µA at 10V. The junction temperature rating reaches 125°C, with a storage temperature range from -40°C to 125°C.
Feature Summary
- Triple line Schottky barrier diode array configuration
- Low forward voltage and low reverse leakage current characteristics
- High ESD strength capability
- Compact surface-mount packaging for space-constrained designs
Applications
- Computer peripheral circuits
- Mobile phone power management
- Portable electronic device protection
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape-and-reel specifications. Confirm that the component status remains active for new designs, as availability may vary. Ensure compliance with RoHS directives if required by the target application environment. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.
Selection Notes
Select this component for applications requiring compact Schottky rectification with low forward voltage drop. The triple-line configuration allows for multiple independent paths within a single small footprint. Verify that the 40V reverse voltage rating exceeds the peak inverse voltage in the circuit. Ensure the 30mA current capacity meets the load requirements. Consider the 125°C junction temperature limit for thermal management planning in enclosed spaces.
Part Context
The RB731 series represents Rohm's standard-grade Schottky barrier diodes designed for general-purpose use in portable electronics. These devices are characterized by low forward voltage and high ESD tolerance. They are not recommended for automotive equipment applications. The RB731XNTR specifically denotes the version packaged in the UMD6 format, suitable for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers for the RB731XNTR were not found in the provided source material. Consult the manufacturer's official replacement guide for verified equivalents.
