Procurement Notes

Verify the specific ordering suffix FHTR against the manufacturer's official documentation to confirm the exact tape and reel quantity and packaging specifications. Ensure the component status is active for new designs, as availability may vary by region. Cross-reference the datasheet revision date to guarantee compliance with current environmental standards and electrical tolerances before finalizing procurement orders.

Selection Notes

Select this component when a compact triple-diode solution is required for low-voltage signal processing or power rectification in space-constrained portable electronics. The UMD6 package offers a small footprint suitable for high-density PCB layouts. Consider the 40V rating and 30mA current capacity to ensure adequate headroom for the target application's peak voltage and current demands without exceeding thermal limits.

Part Context

This part belongs to Rohm's RB731 series of Schottky barrier diodes, which are engineered for low forward voltage and high reliability. The series is widely utilized in consumer electronics due to its efficiency and robustness against electrostatic discharge. The RB731XNFHTR variant specifically utilizes the UMD6 package, providing a balance between performance and miniaturization for modern mobile and computing hardware.
