MBR40L60CTG Equivalent & Substitute Parts

Part Overview

The MBR40L60CTG is a Schottky diode array manufactured by onsemi, configured as 1 pair common cathode with a maximum reverse voltage of 60 V and average rectified current of 20 A per diode. The device is packaged in TO-220-3 through-hole configuration and is part of the SWITCHMODE™ series. This part is currently active in production with 802 pieces in stock.

Equivalent and substitute parts are identified when design requirements allow for alternative components that maintain functional compatibility within specified electrical and mechanical parameters. Substitutes may be necessary due to supply availability, manufacturing discontinuation, or design flexibility within allowable parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR40L60CTG is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 60 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3
• Operating Temperature Range: -55°C to 150°C (minimum)

Allowable Variation Parameters:

• Current - Average Rectified (Io): Equal to or greater than 20 A per diode
• Voltage - Forward (Vf) (Max): Equal to or less than 610 mV @ 20 A
• Current - Reverse Leakage @ Vr: Equal to or less than 550 µA @ 60 V
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these criteria:

Direct Substitute (MBR4060CT): Matches all mandatory parameters with identical reverse voltage, configuration, and package. Forward voltage specification is higher (750 mV @ 20 A), indicating reduced performance efficiency but maintained functional compatibility.

Similar Substitute (48CTQ060): Matches all mandatory parameters with identical reverse voltage, configuration, and package. Current rating is doubled (40 A per diode), providing enhanced current capacity. Forward voltage matches the main part (610 mV @ 20 A).

Parameter Comparison

Engineering Selection Recommendations

MBR40L60CTG (onsemi): Primary selection when onsemi component qualification is required. Active product status with established supply. ROHS3 compliant and REACH unaffected. Suitable for applications requiring the specified 20 A current rating and 610 mV forward voltage characteristics.

MBR4060CT (SMC Diode Solutions): Direct substitute when SMC Diode Solutions qualification is acceptable. Maintains identical reverse voltage, configuration, and package. Forward voltage is 140 mV higher (750 mV @ 20 A), resulting in increased power dissipation. Reverse leakage current is higher (1 mA @ 60 V). ROHS3 compliant with REACH affected status. Higher inventory availability (1900 pieces).

48CTQ060 (SMC Diode Solutions): Similar substitute when enhanced current capacity is beneficial or acceptable. Doubles the current rating to 40 A per diode while maintaining forward voltage at 610 mV @ 20 A. Reverse leakage current is higher (2 mA @ 60 V). ROHS3 compliant with REACH affected status. Highest inventory availability (2562 pieces).

Selection between substitute parts depends on application current requirements, acceptable power dissipation levels, and manufacturer qualification requirements. All three parts maintain functional compatibility within the TO-220-3 through-hole package and 60 V reverse voltage specification.

Frequently Asked Questions (FAQ)

Q: Can MBR4060CT be used as a direct replacement for MBR40L60CTG?

A: MBR4060CT is a direct substitute in terms of configuration, voltage rating, and package. The primary difference is forward voltage: MBR4060CT specifies 750 mV @ 20 A compared to 610 mV @ 20 A for MBR40L60CTG. This 140 mV increase results in higher power dissipation in the diode. Applications with thermal constraints or efficiency requirements must account for this difference.

Q: What is the difference between MBR4060CT and 48CTQ060?

A: Both parts are manufactured by SMC Diode Solutions and share identical reverse voltage (60 V), configuration (1 pair common cathode), and package (TO-220-3). The primary difference is current rating: 48CTQ060 is rated for 40 A per diode compared to MBR4060CT with unspecified current rating. Additionally, 48CTQ060 forward voltage matches MBR40L60CTG at 610 mV @ 20 A, while MBR4060CT specifies 750 mV @ 20 A.

Q: Are all three parts physically interchangeable in TO-220-3 mounting?

A: Yes. All three parts use TO-220-3 through-hole package configuration and are mechanically compatible for PCB mounting. Electrical performance differences require circuit analysis to confirm functional compatibility.

Q: What does "1 Pair Common Cathode" configuration mean?

A: This diode array contains two diodes sharing a common cathode connection. The configuration is essential for specific circuit topologies and cannot be substituted with different configurations.

Q: How do reverse leakage current differences affect circuit performance?

A: MBR40L60CTG specifies 550 µA @ 60 V, while MBR4060CT specifies 1 mA and 48CTQ060 specifies 2 mA. Higher reverse leakage increases standby current and power dissipation. Applications with strict leakage requirements must account for these differences.

Q: Are all parts RoHS3 compliant?

A: Yes. MBR40L60CTG, MBR4060CT, and 48CTQ060 are all ROHS3 compliant. MBR40L60CTG is REACH unaffected, while both SMC Diode Solutions parts are REACH affected.

Q: What is the significance of "Fast Recovery ≤ 500ns, > 200mA (Io)" specification?

A: This specification indicates switching speed performance. All three parts meet this fast recovery criterion, ensuring compatibility in high-frequency switching applications.
