RB471ET148

Overview

The RB471ET148 is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface mount applications. It features a dual configuration within an SOT-25-5 package. The device supports a maximum repetitive reverse voltage of 40 V and a forward current of 100 mA. Key electrical characteristics include a forward voltage of 550 mV and a reverse current of 30 uA. It withstands a forward surge current of 1 A and operates at temperatures up to +125 C.

Feature Summary

• Dual configuration structure integrating two Schottky barriers in a single compact package
• Silicon-based construction optimized for low forward voltage drop performance
• Surface mount design compatible with automated assembly processes

Applications

• General purpose rectification in consumer electronics
• Protection circuits requiring low forward voltage characteristics
• DC-DC converter output rectification stages

Procurement Notes

Verify the specific ordering suffix ET148 to confirm the SOT-25-5 package and reel packaging format. Ensure compatibility with RoHS directives if required by the target application. Cross-reference the manufacturer part number against official ROHM documentation to distinguish from similar series variants with different pinouts or electrical ratings.

Selection Notes

Select this component when a dual Schottky configuration is required in a minimal footprint. The 40 V rating suits low-voltage DC systems. Consider the 100 mA continuous current limit for load requirements. The SOT-25-5 package offers space efficiency compared to discrete dual arrangements. Evaluate thermal management needs based on the 550 mV forward voltage drop at operating currents.

Part Context

This component belongs to the RB471E series of Schottky diodes from ROHM Semiconductor. The series focuses on small-signal rectification with fast switching capabilities. The RB471ET148 variant specifically utilizes the SOT-25-5 outline, providing a standardized solution for dual-diode applications in portable and compact electronic devices.

Replacement Considerations

Check for direct substitutes within the RB471E family that share the SOT-25-5 package. Verify equivalent 40 V reverse voltage and 100 mA forward current ratings. Confirm pinout compatibility before replacing to ensure circuit functionality remains intact.
