Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS20150CG is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Voltage - DC Reverse (Vr) (Max): 150V minimum
• Current - Average Rectified (Io) (per Diode): 10A minimum
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute parts are grouped into two categories:

Category 1: Direct Voltage & Current Equivalents (150V, 10A) Parts that maintain identical voltage and current ratings with the same package configuration. These parts provide direct functional replacement with potential improvements in forward voltage characteristics or leakage current performance.

Category 2: Upgraded Voltage Rating (200V, 10A) Parts that exceed the reverse voltage specification while maintaining current rating. These parts are suitable for applications where higher voltage margin is beneficial and circuit design permits the substitution.

Category 3: Upgraded Current Rating (150V, 25A) Parts that exceed the current specification while maintaining voltage rating. These parts are suitable for applications requiring higher current capacity within the same voltage class.

Parameter Comparison

Engineering Selection Recommendations

MBRB20150CT (SMC Diode Solutions)

This part is the primary direct equivalent for the STPS20150CG. It maintains identical voltage (150V) and current (10A) specifications with the same TO-263-3 D2PAK package configuration. The MBRB20150CT offers active product status, ensuring long-term availability and supply chain continuity. Forward voltage performance is equivalent at 900 mV @ 10 A. This part is ROHS3 compliant and carries MSL 1 rating. Selection of this part is appropriate for direct replacement in existing designs without circuit modification.

MBRB20200CTT4G (onsemi)

This part provides upgraded voltage rating (200V) while maintaining 10A current specification and identical package configuration. The MBRB20200CTT4G carries active product status and is part of the onsemi SWITCHMODE™ series. This part is suitable for applications where increased voltage margin is required or beneficial. Forward voltage performance is equivalent at 900 mV @ 10 A. ROHS3 compliance and MSL 1 rating are maintained. Selection of this part is appropriate when circuit design permits higher voltage rating substitution.

MBRS25150CTHMNG (Taiwan Semiconductor Corporation)

This part maintains the 150V voltage rating while providing upgraded current capacity (25A per diode). The MBRS25150CTHMNG carries active product status and is qualified to AEC-Q101 automotive standard. This part is suitable for applications requiring higher current handling within the same voltage class. Forward voltage at rated current is 1.02 V @ 25 A. ROHS3 compliance and MSL 1 rating are maintained. Selection of this part is appropriate when circuit design requires increased current capacity.

MBRB20200CTG (onsemi)

This part provides upgraded voltage rating (200V) while maintaining 10A current specification. However, this part carries obsolete product status, limiting its suitability for new designs. It is included for reference in legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can MBRB20150CT be used as a direct replacement for STPS20150CG?

A: Yes. The MBRB20150CT maintains identical voltage (150V), current (10A), and package (TO-263-3 D2PAK) specifications. Both parts are configured as 1 pair common cathode Schottky diodes with fast recovery characteristics. The MBRB20150CT offers active product status, making it the preferred direct equivalent.

Q: What is the difference between the STPS20150CG and MBRB20200CTT4G?

A: The primary difference is reverse voltage rating. The MBRB20200CTT4G is rated for 200V maximum reverse voltage compared to 150V for the STPS20150CG. Both parts maintain 10A current rating and identical package configuration. The MBRB20200CTT4G is suitable for applications where higher voltage margin is beneficial.

Q: Is the MBRS25150CTHMNG compatible with the STPS20150CG?

A: The MBRS25150CTHMNG maintains the 150V voltage rating and TO-263-3 D2PAK package configuration. However, it is rated for 25A current per diode compared to 10A for the STPS20150CG. This part is suitable for applications requiring higher current capacity. Circuit design must accommodate the different current rating.

Q: Why is the STPS20150CG listed as obsolete?

A: The STPS20150CG carries obsolete product status, indicating that STMicroelectronics has discontinued active production and support. Active equivalent parts from other manufacturers are available to ensure design continuity and supply chain reliability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (MBRB20150CT, MBRB20200CTG, MBRB20200CTT4G, and MBRS25150CTHMNG) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the STPS20150CG.

Q: What is the significance of the TO-263-3 D2PAK package?

A: The TO-263-3 D2PAK package is a surface mount configuration with 2 leads plus a thermal tab. All listed substitute parts use this identical package, ensuring mechanical and thermal compatibility with existing PCB layouts and thermal management designs.

Q: Can MBRB20200CTG be used in new designs?

A: The MBRB20200CTG carries obsolete product status. While it is functionally compatible with the STPS20150CG, it is not recommended for new designs due to limited availability and discontinued manufacturer support. Active alternatives such as MBRB20200CTT4G are preferred for new applications.

Q: How do forward voltage characteristics compare across substitute parts?

A: The STPS20150CG, MBRB20150CT, MBRB20200CTG, and MBRB20200CTT4G all exhibit 900-920 mV forward voltage at 10A operation. The MBRS25150CTHMNG exhibits 1.02 V forward voltage at its rated 25A current. Forward voltage differences are within typical Schottky diode performance variation and do not preclude substitution.

Q: What is the operating temperature range difference between parts?

A: The STPS20150CG specifies maximum junction temperature of 175°C. The MBRB20150CT and MBRS25150CTHMNG specify -55°C to 150°C operating range. The MBRB20200CTG and MBRB20200CTT4G specify -65°C to 150°C operating range. These differences reflect manufacturer specifications and do not affect substitution suitability for standard industrial applications.
