RB058LAM-40TR

Single Diodes Overview

The RB058LAM-40TR is a single 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 3 A. The device exhibits a low forward voltage of 690 mV at 3 A and a reverse leakage current of 5 µA at 40 V. Packaged in the SOD-128-2 form factor known as PMDTM, it supports a junction temperature up to 150°C and withstands a forward surge current of 90 A.

Single Diodes Feature Summary

• Utilizes PMDTM (Super Low Ir) technology to achieve ultra-low reverse leakage current.
• Features a small power mold type package suitable for high-density surface-mount designs.
• Provides high reliability with a maximum operating junction temperature of 150°C.

Single Diodes Applications

• General-purpose rectification in electronic circuits
• DC-DC converter freewheeling applications
• Power supply output rectification

Single Diodes Procurement Notes

Verify the specific suffix against official Rohm documentation to confirm packaging details and compliance status. Ensure the ordering code matches the required tape-and-reel configuration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a low forward voltage drop and minimal reverse leakage are critical for efficiency. The 40 V rating suits low-voltage DC systems, while the 3 A current capacity handles moderate load requirements. The SOD-128-2 package offers a compact footprint for space-constrained printed circuit board layouts compared to larger through-hole alternatives.

Single Diodes Part Context

This device belongs to the RB058 series of Schottky barrier diodes from Rohm Semiconductor. The series is characterized by its use of PMDTM technology, which distinguishes it from standard silicon rectifiers by offering superior switching characteristics and reduced power loss during conduction cycles.

Single Diodes Replacement Considerations

Direct substitutes include RB058LAM-40TFTR and RB058LAM-40CT, which share identical electrical specifications and package dimensions. Other variants within the RB058 family may serve as functional replacements if voltage or current ratings align with system requirements.
