RB520SM-40T2R

Single Diodes Overview

The RB520SM-40T2R is a single Schottky barrier diode manufactured by Rohm Semiconductor, designed for surface-mount applications in the EMD2 package (SOD-523/SC-79). It features a maximum repetitive reverse voltage of 40 V and an average rectified forward current of 200 mA. The device exhibits a low forward voltage drop of 550 mV at 100 mA and a maximum reverse leakage current of 10 µA at 40 V. It supports a junction temperature up to 150°C and operates within a storage temperature range of -40°C to 150°C.

Single Diodes Feature Summary

• Utilizes silicon epitaxial high-voltage construction for enhanced reliability and low reverse leakage current.
• Features an ultra-small plastic package design suitable for space-constrained portable electronics.
• Provides high electrostatic discharge (ESD) strength capabilities.

Single Diodes Applications

• Computers
• Mobile phones

Single Diodes Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variants such as TR, CT, and Digi-Reel exist for this component. Confirm RoHS compliance status and long-term supply availability before finalizing procurement plans. Ensure the selected package matches the required PCB footprint specifications for the EMD2 form factor.

Single Diodes Selection Notes

Select this component for circuits requiring low forward voltage and minimal reverse leakage in compact designs. It is suitable for general-purpose rectification in consumer electronics but is explicitly not recommended for automotive equipment. Consider the 200 mA current rating and 40 V blocking capability when designing power paths for small signal applications.

Single Diodes Part Context

This part belongs to the RB520 series of Schottky barrier diodes from Rohm Semiconductor. The series is characterized by low VF and IR values with high ESD robustness. The RB520SM-40T2R specifically utilizes the EMD2 package, distinguishing it from other series members that may use different footprints or voltage ratings.

Single Diodes Replacement Considerations

The RB520CS-30 is listed as a similar level replacement with identical pinout and package dimensions, though it offers lower current and voltage ratings. Verify electrical parameter compatibility before substitution.
