Equivalent & Substitute Parts for S5DC-13

Part Overview

The S5DC-13 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 200 V DC reverse voltage and 5 A average rectified current in a surface mount SMC (DO-214AB) package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within acceptable parameter variations for general-purpose rectification applications.

Substitute Part Grouping Explanation

Substitution of the S5DC-13 is determined by the following critical parameters: voltage rating (200 V DC reverse), current rating (5 A average rectified), package type (DO-214AB SMC surface mount), and recovery speed classification (standard or fast recovery). Parts are grouped into two categories:

Parametric Equivalent (Identical Specifications): S5DC-13-F maintains all electrical and mechanical specifications of the original part, differing only in packaging format and product status.

Functional Substitutes (Acceptable Parameter Variations): Parts with matching 200 V voltage rating and SMC package but with current ratings of 3 A, 4 A, or 6 A, or with fast recovery characteristics, are acceptable substitutes when circuit design permits operation at the substitute part's current rating or when improved recovery speed characteristics are compatible with the application.

Engineering Selection Recommendations

Primary Recommendation: S5DC-13-F is the direct equivalent replacement for the discontinued S5DC-13. Both parts are manufactured by Diodes Incorporated with identical electrical specifications and package configuration. S5DC-13-F is currently in active production status with ROHS3 compliance and significantly higher inventory availability (7971 units).

Secondary Recommendations for Current-Rated Substitutes:

STTH4R02S provides the closest current rating match at 4 A with 200 V voltage rating and SMC package. This part is manufactured by STMicroelectronics, carries active product status, and includes ROHS3 compliance. The fast recovery characteristic (≤500ns) is compatible with standard recovery applications. Operating temperature range extends to 175°C maximum junction temperature.

SMLJ60S2-TP offers 6 A current rating with 200 V voltage rating and SMC package, suitable for applications where higher current capacity is acceptable. This part is manufactured by Micro Commercial Co with ROHS3 compliance but carries "Not For New Designs" status.

Lower Current Alternatives:

STTH302S and STTH3R02S both provide 3 A current rating with 200 V voltage rating and SMC package. These parts are manufactured by STMicroelectronics with active product status and ROHS3 compliance. Selection between these two depends on forward voltage requirements: STTH302S specifies 950 mV at 3 A, while STTH3R02S specifies 1 V at 3 A.

Automotive Grade Option:

STTH4R02SY is the automotive-qualified variant of STTH4R02S, designated as Series Q with operating temperature range of -40°C to 175°C. This part is suitable for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can S5DC-13-F be used as a direct replacement for S5DC-13?

A: Yes. S5DC-13-F is the parametric equivalent of S5DC-13, maintaining identical voltage rating (200 V), current rating (5 A), forward voltage (1.15 V @ 5 A), recovery speed (standard >500ns), and package configuration (DO-214AB SMC). The primary differences are packaging format and product status; S5DC-13-F is in active production with ROHS3 compliance.

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

A: Recovery speed refers to the reverse recovery time (trr). Standard recovery diodes have trr >500ns, while fast recovery diodes have trr ≤500ns. Fast recovery diodes exhibit lower reverse recovery current and faster switching characteristics. For general-purpose rectification applications, fast recovery diodes are compatible with standard recovery specifications.

Q: Can STTH4R02S replace S5DC-13 in my circuit?

A: STTH4R02S is compatible if your circuit design permits operation at 4 A instead of 5 A. Both parts share the same 200 V voltage rating, DO-214AB SMC package, and surface mount configuration. STTH4R02S includes fast recovery characteristics and lower reverse leakage current (3 µA vs. 10 µA). Verify that your circuit's maximum current requirement does not exceed 4 A.

Q: Why do some substitute parts have different operating temperature ranges?

A: Operating temperature ranges vary by manufacturer design and qualification. S5DC-13 specifies -65°C to 150°C junction temperature, while STMicroelectronics parts specify -40°C to 175°C. Verify that the substitute part's temperature range meets your application requirements.

Q: What does "Not For New Designs" product status mean?

A: Parts designated as "Not For New Designs" are in mature or declining production phases. While these parts remain available, manufacturers recommend using active production alternatives for new circuit designs. S5DL-TP and SMLJ60S2-TP carry this status; S5DC-13-F and STMicroelectronics parts are in active production.

Q: Are all substitute parts RoHS compliant?

A: S5DC-13 is RoHS non-compliant. All substitute parts listed (S5DC-13-F, S5DL-TP, SMLJ60S2-TP, STTH302S, STTH3R02S, STTH4R02S, STTH4R02SY) are ROHS3 compliant. Verify RoHS compliance requirements for your application before component selection.

Q: What is the difference between STTH4R02S and STTH4R02SY?

A: Both parts are manufactured by STMicroelectronics with identical electrical specifications (200 V, 4 A, fast recovery). STTH4R02SY is designated as Series Q with automotive-grade qualification and operating temperature range of -40°C to 175°C. STTH4R02S operates over -40°C to 175°C without automotive designation. Select STTH4R02SY for applications requiring automotive-grade components.

Q: Can I use a 6 A rated diode (SMLJ60S2-TP) in place of a 5 A rated diode (S5DC-13)?

A: Yes. A higher current-rated diode is compatible in circuits designed for the original 5 A rating. SMLJ60S2-TP provides 6 A capacity with the same 200 V voltage rating and SMC package. The lower forward voltage (1 V @ 6 A vs. 1.15 V @ 5 A) and lower reverse leakage (5 µA vs. 10 µA) are additional benefits. Verify that the substitute part's operating temperature range (-55°C to 150°C) meets your application requirements.
