Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS20M80CFP is determined by the following critical parameters:

Mandatory Matching Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 80 V minimum
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack

Allowable Variation Criteria:

• Current - Average Rectified (Io): Equal to or greater than 10 A per diode
• Voltage - Forward (Vf) (Max) @ If: Within acceptable forward voltage drop range for Schottky diodes
• Current - Reverse Leakage @ Vr: Acceptable within Schottky diode specifications
• Operating Temperature - Junction: Equal to or greater than 175°C maximum

Substitute parts must maintain electrical compatibility with the original circuit design while meeting or exceeding the performance specifications of the STPS20M80CFP.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (80 V Rating):

MBRF2080CT, MBRF2080CTL, and MBRF2080CTP are the preferred substitutes for the STPS20M80CFP. All three parts maintain the 80 V reverse voltage specification and are classified as active products with current manufacturing availability. These parts are ROHS3 compliant and suitable for direct replacement in applications requiring 80 V Schottky diode arrays with TO-220-3 Full Pack configuration.

MBRF2080CT offers 20 A current rating, exceeding the original 10 A specification, providing additional design margin. MBRF2080CTL and MBRF2080CTP both provide equivalent electrical characteristics at the 10 A operating point with forward voltage specifications of 750 mV @ 10 A, closely matching the original 740 mV specification.

Secondary Substitute (60 V Rating):

MBRF2060CTP is suitable only for applications where the circuit design permits operation at 60 V reverse voltage. This part is not a direct replacement for designs requiring 80 V rating but may be used in lower voltage applications. The part is ROHS3 compliant and active in production.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance consistent with the original STPS20M80CFP. The MBRF2080CT is REACH Unaffected, while MBRF2060CTP, MBRF2080CTL, and MBRF2080CTP are REACH Affected. All parts carry EAR99 ECCN classification and 8541.10.0080 HTSUS code.

Frequently Asked Questions (FAQ)

Q: Can MBRF2060CTP be used as a direct replacement for STPS20M80CFP?

A: No. MBRF2060CTP has a maximum reverse voltage rating of 60 V, while STPS20M80CFP is rated for 80 V. Use MBRF2060CTP only in applications where the circuit design operates at 60 V or lower.

Q: What is the difference between MBRF2080CT, MBRF2080CTL, and MBRF2080CTP?

A: All three parts share the same 80 V reverse voltage rating and TO-220-3 Full Pack configuration. MBRF2080CT is manufactured by Taiwan Semiconductor Corporation with 20 A current rating. MBRF2080CTL and MBRF2080CTP are manufactured by SMC Diode Solutions with equivalent electrical characteristics at 10 A operation. Forward voltage specifications are 750 mV @ 10 A for MBRF2080CTL and MBRF2080CTP, compared to 1 V @ 20 A for MBRF2080CT.

Q: Are the substitute parts pin-compatible with STPS20M80CFP?

A: All substitute parts use TO-220-3 Full Pack through-hole configuration. The substitute parts feature isolated tab variants (ITO-220AB), which provide electrical isolation of the tab from the diode cathode. Verify PCB layout and thermal management design to confirm compatibility with isolated tab configuration.

Q: What is the operating temperature range difference between STPS20M80CFP and the substitutes?

A: STPS20M80CFP specifies a maximum junction temperature of 175°C. The substitute parts (MBRF2080CT, MBRF2080CTL, MBRF2080CTP, and MBRF2060CTP) specify operating temperature range of -55°C to 150°C, with maximum junction temperature of 150°C. Applications requiring operation above 150°C junction temperature cannot use these substitutes.

Q: How do reverse leakage currents compare between the original and substitute parts?

A: STPS20M80CFP specifies 30 µA @ 80 V reverse leakage. MBRF2080CT specifies 100 µA @ 80 V, while MBRF2080CTL and MBRF2080CTP specify 1 mA @ 80 V. Applications sensitive to reverse leakage current should evaluate the impact of higher leakage specifications in substitute parts.

Q: What is the significance of the isolated tab feature in substitute parts?

A: The isolated tab (ITO-220AB) in substitute parts electrically isolates the mounting tab from the diode cathode, differing from the standard TO-220-3 Full Pack configuration. This feature affects thermal management and PCB layout. Confirm that the application design accommodates isolated tab configuration before substitution.

Q: Are all substitute parts available in active production status?

A: Yes. MBRF2080CT, MBRF2080CTL, MBRF2080CTP, and MBRF2060CTP are all classified as active products with current manufacturing availability. STPS20M80CFP is obsolete, making these active substitutes necessary for ongoing procurement.
