Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS20SM60CFP is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 60 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack

Allowable Variation Parameters:

• Current - Average Rectified (Io): Equal to or greater than 10 A
• Voltage - Forward (Vf): Within acceptable operating range for the application
• Technology: Schottky or Super Barrier (functionally compatible)
• Speed: Fast Recovery or Standard Recovery
• Operating Temperature Range: Must support minimum 150°C junction temperature

Substitute parts are grouped into two categories: Direct Equivalents (matching all core specifications) and Similar Alternatives (meeting mandatory parameters with enhanced current ratings or alternative technologies).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Preferred Selection:

DSTF2060C (Littelfuse Inc.) is the primary direct equivalent. It maintains identical electrical specifications to the STPS20SM60CFP with 10 A current rating, 60 V reverse voltage, and fast recovery speed characteristics. The part is active in production status and ROHS3 compliant. The isolated tab variant provides enhanced thermal management compared to the original full pack configuration.

Current-Enhanced Alternatives:

MBRF2060CT (Taiwan Semiconductor Corporation) and SBR20U60CTFP-G (Diodes Incorporated) provide 20 A current capability, doubling the original 10 A rating. These parts are suitable for applications requiring higher current capacity while maintaining 60 V voltage rating and through-hole TO-220-3 packaging. Both are active production parts with ROHS3 compliance.

Technology Variant:

SBR2060CTFP-G (Diodes Incorporated) employs Super Barrier technology instead of Schottky, with matching 10 A current rating and 60 V voltage specification. This part exhibits standard recovery speed (>500ns) compared to the fast recovery (≤500ns) of the original device. Selection depends on application recovery speed requirements.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance. MBRF2060CTL and SBRF2060CT are REACH Affected, while DSTF2060C, MBRF2060CT, SBR2060CTFP-G, and SBR20U60CTFP-G are REACH Unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can DSTF2060C directly replace STPS20SM60CFP in existing designs?

A: Yes. DSTF2060C matches all mandatory electrical parameters: 1 pair common cathode configuration, 60 V reverse voltage, 10 A current rating, fast recovery speed, and TO-220-3 through-hole packaging. The isolated tab variant provides equivalent or improved thermal performance. No circuit modifications are required.

Q: What is the difference between the MBRF2060CT and STPS20SM60CFP?

A: MBRF2060CT provides double the current capacity (20 A versus 10 A) while maintaining the same 60 V voltage rating and TO-220-3 packaging. Forward voltage at rated current is higher (950 mV @ 20 A versus 645 mV @ 10 A). This part is suitable for applications requiring higher current handling without circuit redesign.

Q: Why do some substitute parts have unspecified current ratings?

A: MBRF2060CTL and SBRF2060CT do not include current specifications in the provided data. These parts are listed as active alternatives but require verification of current capability through manufacturer datasheets before selection for current-critical applications.

Q: What is the difference between Schottky and Super Barrier technology in these diodes?

A: Both technologies are fast-switching rectifier diodes suitable for the same voltage and package specifications. SBR2060CTFP-G uses Super Barrier technology with standard recovery speed (>500ns), while STPS20SM60CFP uses Schottky technology with fast recovery speed (≤500ns). Selection depends on application switching frequency requirements.

Q: Are all substitute parts available in the same TO-220-3 package?

A: All substitute parts use TO-220-3 Full Pack through-hole packaging. Several variants include an isolated tab feature (DSTF2060C, MBRF2060CT, MBRF2060CTL, SBRF2060CT, SBR2060CTFP-G, SBR20U60CTFP-G), which provides improved thermal isolation compared to the standard full pack configuration.

Q: Which substitute part has the lowest forward voltage drop?

A: STPS20SM60CFP has the lowest forward voltage at 645 mV @ 10 A. Among active substitutes at 10 A rating, DSTF2060C is closest at 650 mV @ 10 A, followed by SBR2060CTFP-G at 700 mV @ 10 A. For 20 A rated parts, forward voltage increases to 710 mV (SBR20U60CTFP-G) and 950 mV (MBRF2060CT).

Q: What is the operating temperature range for substitute parts?

A: STPS20SM60CFP specifies maximum junction temperature of 150°C. All substitute parts support this temperature with operating ranges of -55°C to 150°C (DSTF2060C, MBRF2060CT, MBRF2060CTL, SBRF2060CT) or -65°C to 150°C (SBR2060CTFP-G, SBR20U60CTFP-G), providing equivalent or extended low-temperature capability.

Q: Are there REACH compliance differences between substitute options?

A: DSTF2060C, MBRF2060CT, SBR2060CTFP-G, and SBR20U60CTFP-G are REACH Unaffected. MBRF2060CTL and SBRF2060CT are REACH Affected. For applications requiring REACH Unaffected status, select from the first group.
