MBR1060S Equivalent & Substitute Parts

Part Overview

The MBR1060S is an active Schottky rectifier diode manufactured by SMC Diode Solutions, rated for 60V DC reverse voltage and 10A average rectified current in a surface mount TO-277B package. This component is designed for fast recovery rectification applications requiring high current capacity at moderate voltage levels. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative specifications within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR1060S are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Mandatory Compatibility Parameters:

• Voltage - DC Reverse (Vr) (Max): 60V minimum
• Package / Case: TO-277, 3-PowerDFN (surface mount)
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS3 Compliance

Current Rating Consideration: The MBR1060S is rated for 10A average rectified current. Substitute parts with lower current ratings (such as 5A) are listed as alternatives for applications where the full 10A capacity is not required, provided all other electrical and mechanical parameters remain compatible.

The DST560S-A from Littelfuse Inc. meets the mandatory compatibility criteria with identical voltage rating, package type, temperature range, and fast recovery speed. The primary difference is the reduced current rating of 5A versus 10A, making it suitable for lower-current applications within the same voltage and thermal envelope.

Parameter Comparison

Engineering Selection Recommendations

MBR1060S Selection Criteria: The MBR1060S is the primary choice for applications requiring 10A average rectified current at 60V reverse voltage with fast recovery characteristics. Both the MBR1060S and DST560S-A maintain active product status and full RoHS3 compliance, ensuring long-term availability and regulatory conformance.

DST560S-A Selection Criteria: The DST560S-A is suitable as a substitute when application current requirements do not exceed 5A. This part carries AEC-Q101 automotive qualification, providing additional assurance for automotive-grade applications. The lower current rating results in reduced forward voltage drop at rated current (750 mV @ 5A versus 630 mV @ 10A) and lower junction capacitance (314 pF versus 850 pF), which may provide performance benefits in specific circuit topologies.

Both parts share identical voltage ratings, package configurations, temperature operating ranges, and fast recovery speed specifications, ensuring mechanical and thermal compatibility within their respective current ratings.

Frequently Asked Questions (FAQ)

Q: Can the DST560S-A replace the MBR1060S in all applications?

A: The DST560S-A is a direct mechanical and thermal substitute only for applications where the average rectified current does not exceed 5A. If the application requires sustained current above 5A, the DST560S-A is not suitable. The MBR1060S must be used for full 10A capacity applications.

Q: Are the packages physically identical?

A: Yes. Both the MBR1060S and DST560S-A use the TO-277, 3-PowerDFN surface mount package. They are mechanically interchangeable on the PCB.

Q: What is the difference in forward voltage drop between these parts?

A: The MBR1060S exhibits 630 mV forward voltage drop at 10A, while the DST560S-A exhibits 750 mV at 5A. These measurements are taken at their respective rated currents and are not directly comparable. At lower current levels, forward voltage characteristics differ between the two devices.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The DST560S-A additionally carries AEC-Q101 automotive qualification. Both parts have active product status.

Q: What is the significance of the capacitance difference?

A: The MBR1060S has 850 pF capacitance at 5V, 1MHz, while the DST560S-A has 314 pF. Lower capacitance in the DST560S-A may reduce switching losses and improve high-frequency performance in certain circuit applications, though this depends on specific circuit topology and operating frequency.

Q: Can I use the MBR1060S in place of the DST560S-A?

A: Yes. The MBR1060S can be used as a substitute for the DST560S-A in any application. The higher current rating of the MBR1060S provides additional design margin and is backward compatible with lower-current applications.

Q: What is the reverse leakage current difference?

A: The MBR1060S has 1 mA reverse leakage at 60V, while the DST560S-A has 0.7 mA at 60V. The DST560S-A exhibits lower reverse leakage, which may be beneficial in applications sensitive to leakage current.
