MBR4060PT Equivalent & Substitute Parts

Part Overview

The MBR4060PT is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode rectifier with a maximum reverse voltage rating of 60 V and average rectified current of 40 A per diode. The device is packaged in a TO-247-3 through-hole configuration and is currently in active product status with RoHS3 compliance.

Substitute parts are necessary when the MBR4060PT becomes unavailable, when alternative manufacturers are required for supply chain diversification, or when application requirements permit operation at reduced current ratings while maintaining voltage and thermal specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR4060PT is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 60 V
• Mounting Type: Through Hole
• Package / Case: TO-247-3

Current Rating Consideration: The MBR4060PT operates at 40 A average rectified current per diode. Substitute parts with lower current ratings (20 A, 15 A, or 30 A) are functionally compatible in applications where the circuit does not require the full 40 A capacity. Substitutes with current ratings below 40 A operate within reduced thermal and power dissipation envelopes.

Reverse Leakage Variation: Substitute parts exhibit reverse leakage current variations (ranging from 150 µA to 1 mA at 60 V). These variations remain within acceptable parameters for Schottky rectifier applications.

Temperature Rating: The MBR4060PT specifies a junction temperature range of -55°C to 150°C. Substitute parts from STMicroelectronics specify a maximum junction temperature of 150°C, which is compatible with the MBR4060PT specification.

Engineering Selection Recommendations

Primary Substitute: STPS61L60CW

The STPS61L60CW from STMicroelectronics is the preferred substitute for the MBR4060PT. This device maintains the 60 V reverse voltage rating and provides 30 A average rectified current, which covers 75% of the MBR4060PT capacity. The STPS61L60CW is in active product status with RoHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

Secondary Substitute: 40CPQ060

The 40CPQ060 from SMC Diode Solutions is an active product with RoHS3 compliance. Operating at 20 A average rectified current, this device is suitable for applications requiring reduced current capacity. The 40CPQ060 provides the lowest forward voltage drop at 530 mV @ 20 A among the substitute options.

Alternative Substitute: STPS3060CW

The STPS3060CW from STMicroelectronics operates at 15 A average rectified current and exhibits the lowest reverse leakage current at 150 µA @ 60 V. This device is appropriate for low-leakage applications with reduced current requirements.

Not Recommended: MBR4060WT

The MBR4060WT is obsolete and RoHS non-compliant. Although it maintains the 60 V rating and 1 mA reverse leakage specification, its obsolete status and non-compliance with RoHS3 regulations make it unsuitable for new designs or long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can the STPS61L60CW replace the MBR4060PT in all applications?

A: The STPS61L60CW is electrically compatible with the MBR4060PT for applications operating at or below 30 A average rectified current. Applications requiring the full 40 A capacity of the MBR4060PT require thermal and circuit analysis to confirm adequate performance at the reduced current rating.

Q: What is the difference between the TO-247-3 and TO-247AD package designations?

A: Both designations refer to the same TO-247-3 physical package. The suffix letters (AD, AC) indicate supplier-specific package variants. All substitute parts listed use the TO-247-3 package and are mechanically interchangeable.

Q: Why does the STPS3060CW have lower reverse leakage current than the MBR4060PT?

A: Reverse leakage current variation is a characteristic of different manufacturing processes and die designs across manufacturers. The STPS3060CW exhibits 150 µA @ 60 V compared to the MBR4060PT at 1 mA @ 60 V. Both values are within acceptable parameters for Schottky rectifier applications.

Q: Is the MBR4060WT a viable substitute despite being obsolete?

A: The MBR4060WT is not recommended for new designs. Obsolete products present supply chain risk and may not meet current regulatory requirements. The MBR4060WT is RoHS non-compliant, which disqualifies it from applications requiring RoHS3 certification.

Q: What forward voltage drop should be expected from substitute parts?

A: Forward voltage drops vary by manufacturer and current rating. The 40CPQ060 exhibits 530 mV @ 20 A, the MBR4060WT exhibits 730 mV @ 20 A, and the STPS61L60CW exhibits 660 mV @ 30 A. Forward voltage drop affects power dissipation and thermal performance in the application circuit.

Q: Are all substitute parts through-hole mounted?

A: Yes. All substitute parts listed use through-hole mounting in the TO-247-3 package. No surface-mount alternatives are included in this substitution list.

Q: What is the moisture sensitivity level for these diodes?

A: All parts listed, including the MBR4060PT and all substitutes, have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
