RBR3MM40BTR

Single Diodes Overview

The RBR3MM40BTR is a single Schottky barrier rectifier manufactured by ROHM Semiconductor. It features a silicon construction housed in an SOD-123FL-2 surface-mount package. The device supports a maximum repetitive reverse voltage of 40 V and an average rectified forward current of 3 A. Key electrical parameters include a maximum forward voltage of 580 mV at 3 A, a peak forward surge current capability of 30 A, and a maximum reverse leakage current of 100 uA. The component operates within a junction temperature range up to +150 C.

Single Diodes Feature Summary

• Utilizes low forward voltage technology to minimize power loss during conduction.
• Constructed with high-reliability silicon for stable performance under thermal stress.
• Designed in a compact small power mold type (PMDU) package for efficient space utilization.

Single Diodes Applications

• General-purpose rectification in consumer electronics
• DC-DC converter output stages
• Free-wheeling diodes in switching power supplies

Single Diodes Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm packaging format and tape specifications. Ensure compatibility with standard SMD reflow profiles. Confirm RoHS compliance status through the manufacturer's latest certification records before integration into regulated assemblies.

Single Diodes Selection Notes

Select this component when a 40 V rating and 3 A continuous current capacity are required in a minimal footprint. Compare forward voltage characteristics against alternative packages like SOD-128 if lower leakage or higher surge tolerance is needed. Validate thermal management requirements based on the specified maximum junction temperature limit.

Single Diodes Part Context

This part belongs to the RBR series of Schottky barrier rectifiers from ROHM Semiconductor. It shares the SOD-123FL-2 form factor with other variants such as the RBR2MM40BTR and RBR3MM60BTR, differing primarily in current ratings and voltage breakdown capabilities within the same physical housing.

Single Diodes Replacement Considerations

Direct pin-compatible substitutes within the same package include RBR2MM40BTR for lower current needs or RBR3MM60BTR for higher voltage tolerance. Verify that alternative parts meet the same 3 A forward current and 40 V reverse voltage specifications.
