VS-MBRD320TRR-M3

Single Diodes Overview

The VS-MBRD320TRR-M3 is a high-performance Schottky rectifier manufactured by Vishay Semiconductors, designed for applications requiring low forward voltage drop and small footprints on printed circuit boards. It features a DPAK (TO-252AA) surface-mount package with an anode configuration. The device supports a maximum average forward current of 3.0 A and offers a maximum DC reverse voltage rating of 20 V. Key electrical characteristics include a typical forward voltage drop of 0.49 V at 3 Apk and a junction temperature range from -40 °C to +150 °C.

Single Diodes Feature Summary

• Guard ring structure provides enhanced ruggedness and long-term reliability
• Low forward voltage drop minimizes power loss during operation
• High frequency operation capability suitable for switching applications
• Meets MSL level 1 per J-ST-D-020 standards

Single Diodes Applications

• Disk drives
• Switching power supplies
• Converters
• Freewheeling diodes
• Battery charging circuits
• Reverse battery protection

Single Diodes Procurement Notes

Verify the specific ordering suffix TRR indicates right-oriented tape and reel packaging containing 3000 units per reel. Confirm RoHS compliance and halogen-free status via the M3 designation. Ensure the selected variant matches the required 20 V reverse voltage rating for the VS-MBRD320 series. Validate thermal management requirements against the specified junction-to-case thermal resistance.

Single Diodes Selection Notes

Select this component when a surface-mount Schottky rectifier with a 3.0 A current rating and 20 V reverse voltage capability is required. Consider the DPAK outline for space-constrained designs needing efficient heat dissipation through the base cathode. Evaluate the low forward voltage drop benefits for improving overall system efficiency in high-frequency switching environments.

Single Diodes Part Context

This part belongs to the VS-MBRD3xx-M3 family of high-performance Schottky rectifiers, which also includes variants with 30 V and 40 V ratings. All members share identical physical dimensions, thermal characteristics, and general performance profiles, differing primarily in their maximum DC reverse voltage specifications. The series is engineered for compact surface-mount applications.

Single Diodes Replacement Considerations

Direct substitutes within the same Vishay lineup include VS-MBRD330TRR-M3 (30 V rating) and VS-MBRD340TRR-M3 (40 V rating), provided the higher voltage ratings do not conflict with design constraints. Cross-manufacturer replacements must match the 3.0 A current rating, 20 V minimum reverse voltage, DPAK package, and equivalent forward voltage characteristics.
