Key Parameters

Substitute Part Grouping Explanation

Substitution of the S5GC-13 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Current - Average Rectified (Io): 5 A minimum
• Package / Case: DO-214AB, SMC (surface mount)
• Mounting Type: Surface Mount

Secondary Compatibility Factors:

• Voltage - Forward (Vf) (Max) @ If: ≤ 1.15 V @ 5 A
• Operating Temperature - Junction: -65°C to 150°C minimum range
• Speed: Standard Recovery characteristics

Substitute parts are grouped into two categories:

Category A - Direct Electrical & Mechanical Equivalents (5A Rating): Parts that maintain the 5 A current rating, 400 V voltage rating, and identical forward voltage characteristics within the specified operating temperature range.

Category B - Functional Equivalents with Reduced Current Rating (3A Rating): Parts that maintain the 400 V voltage rating and SMC package but operate at 3 A average rectified current. These are suitable only for applications where the circuit current requirement does not exceed 3 A.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (5 A Applications):

S5GC-13-F (Diodes Incorporated) is the primary direct substitute. This part maintains identical electrical specifications to the S5GC-13, including 5 A current rating, 1.15 V forward voltage at 5 A, and standard recovery characteristics. The S5GC-13-F is active in production, ROHS3 compliant, and available in Tape & Reel packaging with 18,193 units in stock. The operating temperature range (-65°C to 150°C) matches the original specification.

S5G-E3/9AT (Vishay General Semiconductor - Diodes Division) provides equivalent electrical performance with 5 A current rating and 1.15 V forward voltage at 5 A. This part is active in production and ROHS3 compliant. The operating temperature range is -55°C to 150°C, which is narrower at the lower end compared to the S5GC-13. This part is suitable for applications where the -55°C minimum junction temperature is acceptable.

S5GL-TP (Micro Commercial Co) maintains the 5 A current rating and 400 V voltage rating with 1.2 V forward voltage at 5 A. This part carries a "Not For New Designs" status and is therefore not recommended for new product development. It remains available with 11,273 units in stock and is ROHS3 compliant.

For Reduced Current Applications (3 A Maximum):

CMR3U-04 TR13 PBFREE (Central Semiconductor Corp) and STTH3R04S (STMicroelectronics) are functional equivalents rated for 3 A average rectified current at 400 V. Both parts are active in production and ROHS3 compliant. These substitutes are applicable only to circuits where the maximum current requirement does not exceed 3 A. CMR3U-04 TR13 PBFREE exhibits 1.25 V forward voltage at 3 A with fast recovery characteristics. STTH3R04S exhibits 1.5 V forward voltage at 3 A with fast recovery characteristics and a maximum junction temperature of 175°C.

Compliance Considerations:

The S5GC-13 is RoHS non-compliant. All substitute parts listed (S5GC-13-F, S5G-E3/9AT, S5GL-TP, CMR3U-04 TR13 PBFREE, STTH3R04S) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can S5GC-13-F be used as a direct replacement for S5GC-13?

A: Yes. S5GC-13-F is a direct electrical and mechanical equivalent. Both parts share identical voltage ratings (400 V), current ratings (5 A), forward voltage characteristics (1.15 V @ 5 A), recovery speed (standard), and operating temperature range (-65°C to 150°C). The primary difference is product status: S5GC-13-F is active in production while S5GC-13 is discontinued. S5GC-13-F is also ROHS3 compliant.

Q: What is the difference between the 5 A and 3 A rated substitutes?

A: The 5 A rated substitutes (S5GC-13-F, S5G-E3/9AT, S5GL-TP) are suitable for circuits requiring up to 5 A average rectified current. The 3 A rated substitutes (CMR3U-04 TR13 PBFREE, STTH3R04S) are limited to 3 A maximum current. Selection depends on the actual circuit current requirement. Using a 3 A part in a 5 A application will result in component failure.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the DO-214AB SMC surface mount package, maintaining mechanical compatibility with the original S5GC-13. Packaging format differs: S5GC-13-F, S5G-E3/9AT, S5GL-TP, and CMR3U-04 TR13 PBFREE are supplied in Tape & Reel format. STTH3R04S is supplied in Cut Tape and Digi-Reel format. These packaging differences do not affect electrical performance or board-level compatibility.

Q: Why do some substitutes have different forward voltage specifications?

A: Forward voltage variation is a normal characteristic of semiconductor manufacturing. S5GC-13-F and S5G-E3/9AT maintain 1.15 V @ 5 A matching the original. S5GL-TP specifies 1.2 V @ 5 A, which is within acceptable tolerance for general-purpose rectifier applications. The 3 A rated parts (CMR3U-04 TR13 PBFREE at 1.25 V @ 3 A and STTH3R04S at 1.5 V @ 3 A) have higher forward voltages due to their reduced current rating and different semiconductor technology.

Q: What does "Not For New Designs" mean for S5GL-TP?

A: This designation indicates that while S5GL-TP remains available for existing production and repair applications, the manufacturer does not recommend its use in new product designs. For new designs, S5GC-13-F or S5G-E3/9AT are preferred alternatives.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original S5GC-13 is RoHS non-compliant. This compliance difference is significant for applications subject to RoHS regulations or customer requirements.

Q: What is the temperature range difference between substitutes?

A: S5GC-13, S5GC-13-F, and S5GL-TP operate from -65°C to 150°C junction temperature. S5G-E3/9AT operates from -55°C to 150°C, narrower at the lower end. CMR3U-04 TR13 PBFREE and STTH3R04S extend to 175°C maximum junction temperature. Selection depends on the application's thermal requirements.

Q: Can I use STTH3R04S or CMR3U-04 TR13 PBFREE in a 5 A application?

A: No. These parts are rated for 3 A maximum average rectified current. Using them in a 5 A application exceeds their current rating and will cause component failure. They are suitable only for applications where circuit current does not exceed 3 A.

Q: What is the difference between standard and fast recovery?

A: S5GC-13 and its 5 A equivalents use standard recovery (>500 ns). CMR3U-04 TR13 PBFREE and STTH3R04S use fast recovery (≤500 ns). Fast recovery diodes switch more quickly, reducing switching losses in high-frequency applications. For general-purpose rectification at line frequency or low switching rates, both recovery types are functionally equivalent.
