Key Parameters

Substitute Part Grouping Explanation

Substitution of the S5MC-13 is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 1000 V minimum
• Package / Case: DO-214AB, SMC surface mount
• Mounting Type: Surface Mount

Secondary Compatibility Factors:

• Current - Average Rectified (Io): 5 A or greater
• Voltage - Forward (Vf) (Max) @ If: Within acceptable circuit operating margins
• Operating Temperature - Junction: Minimum -55°C to maximum 150°C or greater
• Speed: Standard or faster recovery characteristics

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalents (5 A Rating): Parts maintaining the 5 A current rating with identical voltage specifications and package format.

Category 2 - Functional Alternatives (Higher Current Rating): Parts with 6 A or greater current rating, providing enhanced current capacity while maintaining voltage and package compatibility.

Category 3 - Reduced Current Rating: Parts with lower current ratings (3 A) suitable only for applications where circuit current requirements do not exceed the substitute part's rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: S5MC-13-F

The S5MC-13-F is the direct equivalent substitute for the discontinued S5MC-13. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications: 1000 V reverse voltage, 5 A average rectified current, 1.15 V forward voltage at 5 A, and standard recovery speed characteristics. The S5MC-13-F is currently active in production with higher inventory availability (15,400 pcs) and is ROHS3 compliant, addressing regulatory requirements that the original part does not meet. The packaging format (Cut Tape and Digi-Reel) provides flexibility for both manual and automated assembly processes.

Secondary Recommendation: S5ML-TP

The S5ML-TP, manufactured by Micro Commercial Co, provides functional equivalence with identical voltage and current ratings. Forward voltage is marginally higher at 1.2 V @ 5 A compared to 1.15 V @ 5 A for the S5MC-13. Operating temperature range is reduced to -55°C ~ 150°C. This part is active in production, ROHS3 compliant, and available in Tape & Reel packaging. Selection of this part is appropriate when Diodes Incorporated sourcing is unavailable and the slightly higher forward voltage is acceptable within circuit design margins.

Alternative Recommendation: SMLJ60S10-TP

The SMLJ60S10-TP, manufactured by Micro Commercial Co, provides enhanced current capacity at 6 A versus the 5 A rating of the S5MC-13. This part is suitable for applications where circuit current requirements do not exceed 5 A but where additional current margin is beneficial. The part exhibits lower forward voltage (1 V @ 6 A) and lower reverse leakage current (5 µA @ 1000 V). Operating temperature range is -55°C ~ 150°C. This part is active in production, ROHS3 compliant, and available in Tape & Reel packaging with high inventory (12,900 pcs).

Not Recommended: STTH310S

The STTH310S, manufactured by STMicroelectronics, has a reduced current rating of 3 A, which is below the 5 A specification of the S5MC-13. This part is suitable only for applications where circuit current requirements do not exceed 3 A. The part exhibits fast recovery characteristics (≤ 500ns) and higher forward voltage (1.7 V @ 3 A). Selection of this part requires circuit redesign or confirmation that application current does not exceed 3 A.

Frequently Asked Questions (FAQ)

Q: Can S5MC-13-F be used as a direct replacement for S5MC-13?

A: Yes. The S5MC-13-F is a direct equivalent with identical electrical specifications (1000 V, 5 A, 1.15 V forward voltage) and package format (DO-214AB, SMC). The primary difference is product status (active versus discontinued) and RoHS compliance (ROHS3 compliant versus non-compliant). No circuit modifications are required.

Q: What is the difference between S5MC-13-F and S5ML-TP?

A: Both parts share the same voltage rating (1000 V) and current rating (5 A). The S5MC-13-F is manufactured by Diodes Incorporated with forward voltage of 1.15 V @ 5 A and operating temperature range of -65°C ~ 150°C. The S5ML-TP is manufactured by Micro Commercial Co with forward voltage of 1.2 V @ 5 A and operating temperature range of -55°C ~ 150°C. The S5MC-13-F provides a wider temperature range and lower forward voltage. Selection depends on manufacturer preference and circuit operating conditions.

Q: Can SMLJ60S10-TP replace S5MC-13 in all applications?

A: SMLJ60S10-TP can replace S5MC-13 in applications where circuit current does not exceed 5 A. The 6 A rating of SMLJ60S10-TP provides additional current margin. However, the higher capacitance (150pF @ 4V, 1MHz versus 40pF @ 4V, 1MHz) and lower forward voltage (1 V @ 6 A versus 1.15 V @ 5 A) may affect circuit performance in high-frequency or precision applications. Circuit analysis is required to confirm compatibility.

Q: Why is STTH310S not recommended as a substitute?

A: The STTH310S has a current rating of 3 A, which is below the 5 A specification of S5MC-13. This part is suitable only for applications where circuit current requirements do not exceed 3 A. Additionally, the forward voltage is higher (1.7 V @ 3 A), which may increase power dissipation. Use of this part requires confirmation that application current does not exceed 3 A and that the higher forward voltage is acceptable.

Q: What packaging options are available for substitute parts?

A: S5MC-13-F is available in Cut Tape (CT) and Digi-Reel packaging. S5ML-TP and SMLJ60S10-TP are available in Tape & Reel (TR) packaging. All parts use the DO-214AB, SMC surface mount package format. Selection of packaging depends on assembly process requirements and volume considerations.

Q: Are all substitute parts RoHS compliant?

A: S5MC-13-F, S5ML-TP, SMLJ60S10-TP, and STTH310S are all ROHS3 compliant. The original S5MC-13 is RoHS non-compliant. Selection of any substitute part addresses RoHS compliance requirements.

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

A: S5MC-13 and S5MC-13-F operate from -65°C to 150°C. S5ML-TP and SMLJ60S10-TP operate from -55°C to 150°C. STTH310S operates from -40°C to 175°C. Applications requiring operation below -55°C must use S5MC-13 or S5MC-13-F. Applications requiring operation above 150°C must use STTH310S.

Q: How do forward voltage differences affect circuit design?

A: Forward voltage differences directly impact power dissipation and voltage drop across the diode. S5MC-13 and S5MC-13-F have 1.15 V @ 5 A. S5ML-TP has 1.2 V @ 5 A (0.05 V higher). SMLJ60S10-TP has 1 V @ 6 A (0.15 V lower). STTH310S has 1.7 V @ 3 A (0.55 V higher). Circuit analysis is required to confirm that forward voltage variations remain within acceptable design margins.
