RB520ZS-40T2R

Single Diodes Overview

The RB520ZS-40T2R is a Schottky barrier diode manufactured by Rohm Semiconductor, designed for surface-mount applications. It features a maximum repetitive reverse voltage of 40 V and an average rectified forward current of 100 mA. The device utilizes the GMD-2 package, which corresponds to the SOD-323 footprint. Key electrical characteristics include a maximum forward voltage of 450 mV at a forward current of 10 mA and a maximum reverse leakage current of 1 µA at 40 V. The component supports a maximum operating junction temperature of 150 °C and is supplied in tape and reel packaging.

Single Diodes Feature Summary

• Utilizes silicon epitaxial planar structure for high reliability and low reverse leakage current.
• Features a compact plastic surface-mount package suitable for automated assembly processes.
• Provides fast switching performance with low forward voltage drop characteristics.

Single Diodes Applications

• DC-DC converter circuits
• Power supply rectification
• Freewheeling diodes in inductive load protection

Single Diodes Procurement Notes

Verify the specific suffix 'ZS' against the official Rohm datasheet to confirm the exact package type and marking code, as variations exist within the RB520 series. Ensure the ordering part number matches the required taping specifications for your manufacturing line. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or the manufacturer's official channels prior to procurement.

Single Diodes Selection Notes

Select this component when a 40 V reverse voltage rating and 100 mA continuous current capacity are required in a small surface-mount form factor. Compare the forward voltage and reverse leakage specifications against alternative Schottky diodes to ensure compatibility with low-power efficiency targets. Confirm that the thermal management requirements align with the 150 °C junction temperature limit for the intended operating environment.

Single Diodes Part Context

This component belongs to the RB520 series of Schottky barrier diodes from Rohm Semiconductor. The series is characterized by low forward voltage and low reverse current, making it suitable for general-purpose rectification in portable electronic devices. The RB520ZS variant specifically denotes the GMD-2 package configuration, distinguishing it from other pin-compatible or functionally similar parts in the broader product family.

Single Diodes Replacement Considerations

Consult the official Rohm replacement guide for direct equivalents. Potential substitutes may include other Schottky diodes with matching 40 V ratings and 100 mA current capabilities in the SOD-323 package. Verify pinout compatibility and thermal characteristics before substitution.
