MBRB3060CT Equivalent & Substitute Parts

Part Overview

The MBRB3060CT is a Schottky diode array manufactured by SMC Diode Solutions, configured as 1 pair common cathode with a maximum reverse voltage of 60 V and average rectified current of 30 A per diode. The component is housed in a Surface Mount TO-263-3 D2PAK package and is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or when design specifications permit operation at lower current ratings while maintaining voltage and package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBRB3060CT 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: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Lower ratings acceptable for reduced current applications
• Voltage - Forward (Vf) (Max): Variation within Schottky diode technology range
• Current - Reverse Leakage @ Vr: Variation acceptable within Schottky specifications
• Operating Temperature - Junction: Extended range acceptable
• RoHS and MSL compliance: Must maintain or exceed original specifications

The identified substitute parts MBRB1060CT and NRVBB30H60CTT4G satisfy all mandatory matching parameters. Current rating differences reflect application-specific requirements where lower current capacity is acceptable.

Parameter Comparison

Engineering Selection Recommendations

MBRB3060CT (Primary Selection)

The MBRB3060CT is the specified component for applications requiring 30 A average rectified current per diode at 60 V reverse voltage. This part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection is appropriate for high-current rectification circuits where the full 30 A rating is utilized.

MBRB1060CT (Littelfuse Inc. Substitute)

The MBRB1060CT is suitable for applications where current requirements do not exceed 5 A per diode. This part maintains identical package configuration, voltage rating, and fast recovery speed characteristics. ROHS3 compliance and MSL 1 rating are preserved. The lower current rating results in reduced forward voltage drop (700 mV @ 5 A versus 770 mV @ 15 A) and lower reverse leakage current (1 mA @ 60 V). This substitute is appropriate for low-current rectification applications within the 5 A per diode limit.

NRVBB30H60CTT4G (onsemi Substitute)

The NRVBB30H60CTT4G is suitable for applications requiring 15 A average rectified current per diode at 60 V reverse voltage. This part maintains identical package configuration and voltage rating with extended operating temperature range (-55 to 175 °C versus -55 to 150 °C). Forward voltage drop is lower (620 mV @ 15 A) and reverse leakage current is significantly lower (300 µA @ 60 V). ROHS3 compliance and MSL 1 rating are preserved. This substitute is appropriate for mid-range current rectification applications within the 15 A per diode limit.

All substitute parts maintain mandatory electrical and mechanical compatibility parameters with identical TO-263-3 D2PAK packaging, 60 V reverse voltage rating, Schottky technology, and fast recovery speed characteristics.

Frequently Asked Questions (FAQ)

Q: Can MBRB1060CT be used in place of MBRB3060CT in all applications?

A: MBRB1060CT is suitable only for applications where the average rectified current requirement does not exceed 5 A per diode. The MBRB3060CT is rated for 30 A per diode. If the circuit requires current exceeding 5 A, MBRB1060CT will not provide adequate current capacity. Package, voltage rating, and technology are identical.

Q: What is the primary difference between NRVBB30H60CTT4G and MBRB3060CT?

A: The primary difference is current rating. NRVBB30H60CTT4G is rated for 15 A average rectified current per diode, while MBRB3060CT is rated for 30 A. Both maintain 60 V reverse voltage rating, identical TO-263-3 D2PAK packaging, Schottky technology, and fast recovery speed. NRVBB30H60CTT4G offers extended operating temperature range to 175 °C and lower forward voltage drop.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use identical TO-263-3 D2PAK (2 Leads + Tab) TO-263AB packaging with the same pinout configuration. Physical and electrical pin compatibility is maintained across all substitute parts.

Q: Do the substitute parts maintain RoHS and MSL compliance?

A: Yes. Both MBRB1060CT and NRVBB30H60CTT4G maintain ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original MBRB3060CT specifications.

Q: What is the impact of forward voltage drop differences between the parts?

A: Forward voltage drop varies with current rating. MBRB3060CT exhibits 770 mV @ 15 A, MBRB1060CT exhibits 700 mV @ 5 A, and NRVBB30H60CTT4G exhibits 620 mV @ 15 A. Lower forward voltage drop reduces power dissipation and heat generation. Selection should be based on actual circuit current requirements and thermal design constraints.

Q: Can MBRB3060CT be substituted with NRVBB30H60CTT4G in a 30 A application?

A: No. NRVBB30H60CTT4G is rated for maximum 15 A average rectified current per diode. Using this part in a 30 A application exceeds its current rating and will result in component failure or degraded performance.

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

A: Reverse leakage current affects circuit performance in low-current or high-impedance applications. MBRB3060CT exhibits 5 mA @ 60 V, MBRB1060CT exhibits 1 mA @ 60 V, and NRVBB30H60CTT4G exhibits 300 µA @ 60 V. Lower reverse leakage current reduces parasitic current paths and improves circuit efficiency in sensitive applications.
