MBR3060PT Equivalent & Substitute Parts

Part Overview

The MBR3060PT is a Schottky diode array manufactured by Diodes Incorporated, configured as 1 pair common cathode with 60V reverse voltage rating and 30A average rectified current per diode. The device is packaged in TO-3P-3 (SC-65-3) through-hole configuration and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR3060PT 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
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Flexible Parameters (Allow Variation):

• Current - Average Rectified (Io): Substitutes may have equal or higher current ratings
• Package / Case: TO-247-3 variants acceptable as functional equivalents with different form factors
• Voltage - Forward (Vf): Variation permitted within Schottky diode specifications
• Current - Reverse Leakage: Variation permitted within acceptable ranges
• Operating Temperature Range: Variation permitted if minimum temperature ≥ -55°C and maximum ≥ 150°C

Substitute parts are grouped into two categories: direct equivalents (matching current rating) and higher-current alternatives (exceeding 30A rating).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant):

The MBR3060PT (Taiwan Semiconductor Corporation) in TO-247-3 package is the preferred direct equivalent. It maintains the 60V reverse voltage, 30A current rating, and 1 pair common cathode configuration while offering active product status and ROHS3 compliance. The package change from TO-3P-3 to TO-247-3 requires PCB layout modification but provides superior thermal performance and wider industry availability.

The DSSK80-006B (IXYS) is suitable for applications requiring higher current capacity. With 40A rating and active status, it provides design margin for current-intensive applications. ROHS3 compliance and superior forward voltage characteristics (550 mV @ 40 A) make it appropriate for efficiency-critical designs.

Secondary Substitutes (Active Status, Current Rating Consideration):

The STPS3060CW (STMicroelectronics) and MBR3060WT (SMC Diode Solutions) are active alternatives with 15A and unspecified current ratings respectively. These are suitable only for applications where the 30A requirement can be reduced or where parallel configurations are implemented. Both maintain ROHS3 compliance and TO-247-3 packaging.

Not Recommended for New Designs:

The 30CPQ060 and STPS30L60CW are obsolete products with RoHS non-compliance. These parts should not be selected for new designs despite their technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MBR3060PT be directly replaced with the Taiwan Semiconductor Corporation MBR3060PT?

A: Yes. Both parts share identical electrical specifications (60V, 30A, Schottky, common cathode configuration). The primary difference is packaging: the original uses TO-3P-3 while the substitute uses TO-247-3. PCB layout modification is required, but electrical performance is equivalent.

Q: What is the difference between the MBR3060PT and DSSK80-006B?

A: The DSSK80-006B has a higher current rating (40A vs. 30A) and lower forward voltage (550 mV @ 40 A vs. 800 mV @ 30 A). Both maintain 60V reverse voltage and Schottky technology. The DSSK80-006B is suitable for applications requiring higher current capacity or improved efficiency.

Q: Why are 15A-rated parts listed as substitutes for a 30A device?

A: Parts such as STPS3060CW and 30CPQ060 are listed as cross-references but are not direct substitutes due to reduced current rating. They are applicable only in designs where current requirements have been reduced or where multiple devices are paralleled.

Q: Is the TO-247-3 package compatible with TO-3P-3 PCB layouts?

A: No. TO-247-3 and TO-3P-3 have different pin configurations and footprints. PCB redesign is required when substituting between these packages. However, both are through-hole packages with similar thermal and electrical performance characteristics.

Q: Which substitute part offers the best RoHS compliance?

A: All active substitute parts (MBR3060PT from Taiwan Semiconductor Corporation, MBR3060WT, DSSK80-006B, and STPS3060CW) are ROHS3 compliant. The obsolete parts (30CPQ060 and STPS30L60CW) are RoHS non-compliant and unsuitable for new designs subject to RoHS regulations.

Q: What is the operating temperature range consideration for substitution?

A: The original MBR3060PT operates from -65°C to 150°C. Most substitutes operate from -55°C to 150°C, which is acceptable for most applications. Verify minimum temperature requirements for your specific application before selection.

Q: Can STPS3060CW be used in place of MBR3060PT in high-current applications?

A: No. The STPS3060CW is rated for 15A, which is half the original 30A specification. Use only in applications where current requirements are confirmed to be 15A or less, or implement parallel configurations with appropriate current-sharing design.
