Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR40150PTH is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Mounting Type: Through Hole
• Package / Case: TO-247-3
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Current Rating Consideration: The MBR40150PTH is rated for 40 A average rectified current per diode. Substitute parts are grouped by their current rating capability. Parts rated at 40 A provide direct equivalence. Parts rated below 40 A (15 A, 20 A, 30 A) are functional substitutes where circuit design permits operation at reduced current capacity.

Compliance Parameters: All substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with manufacturing and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (40 A Rating): The STPS80150CW manufactured by STMicroelectronics provides direct electrical equivalence to the MBR40150PTH. Both devices are rated for 40 A average rectified current at 150 V reverse voltage in TO-247-3 through-hole packaging. The STPS80150CW offers improved forward voltage characteristics (840 mV @ 40 A versus 1.01 V @ 40 A) and lower reverse leakage current (30 µA versus 100 µA), with extended maximum junction temperature rating (175°C versus 150°C). This part is ROHS3 compliant and maintains MSL 1 rating. Inventory availability is 2,840 units.

Reduced Current Alternatives: The STPS61150CW (30 A), STPS40150CW (20 A), and STPS30150CW (15 A) are functional substitutes where circuit design accommodates reduced current capacity. These parts maintain 150 V reverse voltage rating, TO-247-3 packaging, and Schottky technology. All STMicroelectronics parts feature superior forward voltage performance and lower reverse leakage compared to the main part, with maximum junction temperature of 175°C.

The MBR30150WT manufactured by SMC Diode Solutions provides an alternative from a different manufacturer while maintaining 150 V rating and TO-247-3 packaging. Current rating is not specified in available data. This part carries REACH Affected status, distinguishing it from REACH Unaffected alternatives.

Compliance and Qualification: The MBR40150PTH carries AEC-Q101 automotive qualification. Substitute parts should be evaluated for automotive qualification requirements in specific applications. All listed substitutes maintain ROHS3 compliance and MSL 1 rating, supporting standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can STPS80150CW directly replace MBR40150PTH in all applications?

A: The STPS80150CW provides direct electrical equivalence with identical 40 A current rating and 150 V reverse voltage in TO-247-3 packaging. Both devices employ Schottky technology with fast recovery characteristics. The STPS80150CW offers improved electrical performance with lower forward voltage and reverse leakage. Substitution is valid where automotive qualification requirements do not mandate AEC-Q101 certification specifically for the Taiwan Semiconductor Corporation part number.

Q: What is the difference between 40 A and 30 A rated parts?

A: Current rating indicates the maximum average rectified current per diode the device is designed to conduct continuously. The MBR40150PTH and STPS80150CW are rated for 40 A, while STPS61150CW is rated for 30 A. Selection of a 30 A part for a 40 A application would exceed the device rating and is not permitted. Conversely, using a 40 A rated part in a 30 A application operates within specification.

Q: Are all substitute parts available in the same TO-247-3 package?

A: Yes. All listed substitute parts are packaged in TO-247-3 through-hole format, providing identical mechanical compatibility and PCB mounting characteristics. No layout or mechanical redesign is required for package substitution.

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

A: Forward voltage (Vf) represents the voltage drop across the diode during forward conduction. The MBR40150PTH exhibits 1.01 V @ 40 A, while STPS80150CW exhibits 840 mV @ 40 A. Lower forward voltage reduces power dissipation and heat generation. In high-current applications, this difference impacts thermal management and overall circuit efficiency. Selection should account for thermal design requirements and power budget constraints.

Q: Can I use STPS30150CW (15 A) in place of MBR40150PTH (40 A)?

A: STPS30150CW is rated for 15 A average rectified current. Using this part in an application requiring 40 A operation exceeds the device rating and is not permitted. This part is suitable only for applications designed for 15 A or lower current operation.

Q: What does REACH Affected versus REACH Unaffected mean for part selection?

A: REACH Affected status indicates the part may contain substances of concern regulated under REACH (Registration, Evaluation, Authorization and Restriction of Chemicals). REACH Unaffected parts do not contain such substances. Selection between MBR30150WT (REACH Affected) and alternatives should consider regulatory compliance requirements for the end application and geographic market.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, indicating conformance to Restriction of Hazardous Substances requirements. This ensures compatibility with standard manufacturing processes and environmental regulations.

Q: What is MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has unlimited shelf life without special moisture control measures. All listed parts carry this rating, permitting standard storage and handling without desiccant packaging or controlled humidity requirements.
