MBR0540T1G

Single Diodes Overview

The MBR0540T1G is a surface mount Schottky power rectifier manufactured by onsemi, housed in an SOD-123 package. It features a peak repetitive reverse voltage of 40 V and an average rectified forward current of 0.5 A at a case temperature of 115°C. The device supports a non-repetitive peak surge current of 5.5 A and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum instantaneous forward voltage of 0.51 V at 0.5 A and 25°C, with a maximum reverse current of 20 µA at 40 V and 25°C.

Single Diodes Feature Summary

• Employs a Schottky barrier principle with optimized forward voltage drop and reverse current tradeoff for low voltage, high frequency applications.
• Includes a guardring structure designed to provide stress protection for the device.
• Epoxy molding compound meets UL 94 V-0 flammability rating at 0.125 inches thickness.
• Package is designed for optimal automated board assembly processes.

Single Diodes Applications

• Low voltage, high frequency rectification circuits
• Free wheeling diodes in surface mount designs
• Polarity protection diodes where compact size is critical

Single Diodes Procurement Notes

Verify that the ordering suffix matches the required tape and reel quantity, as T1 indicates 3,000 units per reel while T3 indicates 10,000 units. Confirm the presence of the NRVB prefix if automotive qualification or specific site control changes are mandated by the design requirements. Ensure compliance with Pb-Free specifications and check for the C0071 marking indicator on the component body.

Single Diodes Selection Notes

Select this component when a compact surface mount solution is required for efficient rectification in low voltage environments. The SOD-123 package offers a smaller footprint compared to leadless MELF styles. Consider the thermal resistance values and derating curves if operating near the maximum temperature limits or under high reverse bias conditions to prevent thermal runaway.

Single Diodes Part Context

This part belongs to the MBR0540 series of Schottky Power Rectifiers from onsemi. It serves as a surface mount alternative to traditional leadless packages, providing similar electrical performance in a standardized SOD-123 form factor. The series includes variants like the MBR0540T3G and automotive-specific NRVB prefixes, all sharing the same core semiconductor die and electrical ratings.

Single Diodes Replacement Considerations

The datasheet lists MBR0540T3G, NRVB0540T1G, and NRVB0540T3G as related parts within the same product family. These share identical electrical characteristics but differ in packaging quantities or automotive qualification status. No other external substitute part numbers are confirmed in the provided documentation.
