RB530XNFHTR

Overview

The RB530XNFHTR is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a single-diode configuration housed in an ultra-small EMD2 package (SOD-523), measuring 1.6 x 0.8 mm with a thickness of 0.7 mm. The device supports automotive reliability standards under AEC-Q101. Key electrical specifications include a maximum repetitive reverse voltage of 40 V and an average rectified forward current of 100 mA. The forward voltage is specified at a maximum of 0.71 V at 100 mA, while the reverse leakage current is limited to 15 µA at 40 V. The component operates within a junction temperature range up to 150 °C.

Feature Summary

• Ultra-small mold type construction for compact circuit board layouts
• High reliability suitable for automotive electronic systems
• Low forward voltage characteristics for improved efficiency

Applications

• Automotive small current rectification circuits
• General-purpose high-reliability surface mount electronics
• Portable devices requiring minimal footprint components

Procurement Notes

Verify the specific suffix FHTR against official ROHM documentation to confirm the exact tape-and-reel packaging quantity and lead time requirements. Ensure the ordering part number matches the intended automotive grade specifications. Cross-reference the datasheet revision date to confirm compliance with current RoHS directives and material declarations before finalizing procurement orders.

Selection Notes

Select this component when a low-profile SMD Schottky diode with automotive qualification is required. The EMD2 package offers significant space savings compared to standard SOD-923 or SOD-323 packages. Consider the 40 V rating and 100 mA current capacity for low-power DC-DC converter output rectification or signal clamping applications where thermal performance and physical size are critical constraints.

Part Context

This part belongs to the RB530 series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by its silicon epitaxial planar structure and is optimized for high-speed switching applications. The RB530XNFHTR specifically denotes the automotive-grade variant with the EMD2 package, distinguishing it from general-purpose counterparts like the RB530CM or RB530VM series which may utilize different package types such as SOD-923 or SOD-323FL.

Replacement Considerations

Direct pin-compatible replacements within the same family include the RB530SM-40FHTE-17, which shares the EMD2 package and similar electrical ratings. Verify that any substitute maintains the AEC-Q101 automotive qualification if used in vehicle applications. General-purpose equivalents like the RB530CM-40T2R offer similar functionality but differ in package dimensions and potentially in automotive certification status.
