MBRS4060CT Equivalent & Substitute Parts

Part Overview

The MBRS4060CT is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as 1 pair common cathode with a maximum reverse voltage of 60V and average rectified current of 40A per diode. The device is housed in a TO-263-3 D2PAK surface mount package and is classified as Active product status with full RoHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges. The MBRS4060CT serves applications requiring high-current rectification with fast recovery characteristics, and alternative sources may be required due to inventory availability, supply chain considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBRS4060CT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 60V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Current Rating Consideration: The MBRS4060CT specifies 40A average rectified current per diode. Substitute parts with lower current ratings (such as 20A) operate within the same voltage and package specifications but with reduced current capacity. Such parts are classified as functional substitutes for applications where the full 40A rating is not required.

The 48CTQ060S from SMC Diode Solutions meets all mandatory matching parameters with identical reverse voltage, package configuration, and fast recovery speed characteristics. However, the current rating differs at 20A per diode versus 40A for the primary part.

Parameter Comparison

Engineering Selection Recommendations

MBRS4060CT (Primary Part): The MBRS4060CT is the specified component with Active product status and full RoHS3 compliance. This part is suitable for applications requiring 40A average rectified current at 60V reverse voltage with operating junction temperatures up to 175°C. The REACH Unaffected status indicates no substance of concern restrictions. Current inventory of 964 pieces supports immediate availability.

48CTQ060S (Substitute Part): The 48CTQ060S is an Active product from SMC Diode Solutions with identical package configuration and voltage rating. This part is suitable for applications where the current requirement does not exceed 20A per diode. The part maintains RoHS3 compliance and fast recovery speed characteristics. The maximum operating junction temperature is 150°C, which is 25°C lower than the primary part. Current inventory of 1498 pieces is available. REACH Affected status indicates the presence of substances of concern; compliance verification with end-application requirements is necessary.

Selection between these parts is determined by the application's current requirement. The 48CTQ060S is a direct mechanical and electrical substitute only for circuits designed for 20A operation or lower.

Frequently Asked Questions (FAQ)

Q: Can the 48CTQ060S replace the MBRS4060CT in all applications?

A: The 48CTQ060S is mechanically and electrically compatible in package and voltage rating but has a reduced current capacity of 20A per diode compared to 40A for the MBRS4060CT. Substitution is valid only for applications where the circuit current requirement does not exceed 20A per diode.

Q: Are the D2PAK packages identical between both parts?

A: Both parts use the TO-263-3 D2PAK package with 2 leads plus tab configuration. The mechanical footprint and pinout are identical, allowing direct PCB layout compatibility.

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

A: The MBRS4060CT specifies 1V forward voltage at 40A, while the 48CTQ060S specifies 610mV at 20A. Forward voltage characteristics are measured at their respective rated currents and are not directly comparable across different current levels.

Q: Does the operating temperature range difference affect substitution?

A: The MBRS4060CT operates to 175°C junction temperature, while the 48CTQ060S operates to 150°C. Applications requiring operation above 150°C junction temperature require the MBRS4060CT.

Q: What is the significance of the reverse leakage current difference?

A: The MBRS4060CT specifies 100µA reverse leakage at 60V, while the 48CTQ060S specifies 2mA at 60V. The 48CTQ060S exhibits higher reverse leakage current. Applications sensitive to leakage current performance should use the MBRS4060CT.

Q: Are both parts RoHS compliant?

A: Both parts are RoHS3 compliant. The MBRS4060CT is REACH Unaffected, while the 48CTQ060S is REACH Affected. End-application REACH compliance requirements must be verified for the 48CTQ060S.

Q: What packaging formats are available for these parts?

A: The MBRS4060CT is supplied in Tape & Reel (TR) format. The 48CTQ060S is supplied in Cut Tape (CT) and Digi-Reel® format. Packaging format selection depends on assembly process requirements and order quantities.
