RB501SM-30FHT2R

Single Diodes Overview

The RB501SM-30FHT2R is a single Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface-mount applications in the SOD-523 (EMD2) package. It features a silicon epitaxial planar structure with a maximum repetitive reverse voltage of 30 V and an average rectified forward current of 100 mA. The device exhibits a low forward voltage of 0.35 V at 10 mA and a maximum reverse current of 10 µA at 10 V. It supports a forward surge current of 1 A and operates within a junction temperature range up to 125°C, meeting AEC-Q101 automotive qualification standards.

Single Diodes Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Low forward voltage characteristic for improved efficiency
• Compact SOD-523 surface-mount packaging

Single Diodes Applications

• Small current rectification circuits
• Automotive electronic systems requiring high reliability
• General-purpose power supply output rectification

Single Diodes Procurement Notes

Verify the specific suffix FHT2R against the official datasheet to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure the component meets the required AEC-Q101 qualification level for the intended application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and traceability before procurement.

Single Diodes Selection Notes

Select this component when a compact Schottky diode with automotive qualification is required for low-current rectification. The 30 V reverse voltage rating suits low-voltage DC bus applications. Compare the 100 mA forward current capability against circuit load requirements. Consider the SOD-523 footprint constraints during PCB layout design to ensure adequate thermal dissipation and mechanical stability.

Single Diodes Part Context

This component belongs to the RB501SM series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by small mold types and low forward voltage drops, targeting space-constrained designs. The RB501SM variant specifically offers 100 mA current handling, distinguishing it from higher-current siblings like the RB521 or lower-current models within the same package family.

Single Diodes Replacement Considerations

The RB501VM-40FHTE-17 serves as a functional substitute but utilizes the SOD-323FL package rather than SOD-523. Verify pinout compatibility and physical footprint differences before substitution. The VM series offers a higher voltage rating but requires board re-layout due to package size variation.
