SMLJ60S2-TP Equivalent & Substitute Parts

Part Overview

The SMLJ60S2-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 6 A average rectified current in a surface mount SMC (DO-214AB) package. This part is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute components is necessary to maintain design continuity, support existing production requirements, or transition to active alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the SMLJ60S2-TP is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 200 V
Package / Case: Must be DO-214AB, SMC (surface mount)
Mounting Type: Must be Surface Mount
RoHS Status: Must maintain ROHS3 Compliance

Current Rating Considerations: The SMLJ60S2-TP is rated for 6 A average rectified current. Substitute parts are grouped into two categories:

Direct Current Rating Substitutes (5 A - 6 A): Parts with 5 A or 6 A ratings that operate within the same thermal and electrical envelope. These include CGRC503-G (5 A) and S5DC-13-F (5 A). A 5 A rated device can substitute for a 6 A application when the actual circuit current demand does not exceed 5 A.
Reduced Current Rating Substitutes (3 A): Parts rated for 3 A average rectified current, including ES3D-13-F, ES3D, MURS320-13-F, MURS320T3G, RS3D-13-F, S3D, S3D-13-F, and STTH302S. These are suitable only when circuit current requirements do not exceed 3 A.

Recovery Speed Variations: Substitute parts exhibit either Standard Recovery (>500 ns) or Fast Recovery (≤500 ns) characteristics. Both recovery types are electrically compatible with the SMLJ60S2-TP application, as recovery speed does not affect DC reverse voltage or forward voltage performance at rated current.

Product Status Consideration: The SMLJ60S2-TP is "Not For New Designs." Active substitute parts (Product Status: Active) are preferred for new applications and ongoing production support.

Engineering Selection Recommendations

For Applications Requiring 5 A - 6 A Current Rating:

CGRC503-G and S5DC-13-F are the primary substitutes when circuit current demand reaches or approaches 6 A. Both parts maintain 200 V reverse voltage rating and DO-214AB package compatibility. CGRC503-G is manufactured by Comchip Technology with Active product status. S5DC-13-F is manufactured by Diodes Incorporated with Active product status. Both are ROHS3 compliant and suitable for new designs.

For Applications Requiring 3 A Current Rating or Lower:

Multiple active alternatives exist with varying recovery speed characteristics:

Fast Recovery Options (≤500 ns): ES3D-13-F, ES3D, MURS320-13-F, MURS320T3G, and STTH302S provide improved switching performance. MURS320-13-F and MURS320T3G support extended operating temperature ranges to 175°C. STTH302S offers the lowest reverse leakage current (3 µA @ 200 V).
Standard Recovery Options (>500 ns): S3D-13-F and CGRC503-G maintain recovery characteristics similar to the SMLJ60S2-TP. S3D-13-F is manufactured by Diodes Incorporated with extensive inventory availability (295,099 pcs).

Compliance and Certification:

All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the SMLJ60S2-TP. All parts carry EAR99 ECCN classification and 8541.10.0080 HTSUS code, maintaining export and trade compliance consistency.

Product Status Priority:

Avoid S3D (Obsolete status). Prioritize Active status parts for new designs and long-term production support. The SMLJ60S2-TP "Not For New Designs" status necessitates transition to Active alternatives for ongoing applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 3 A rated diode in place of the 6 A SMLJ60S2-TP?

A: Only if your circuit current demand does not exceed 3 A. The 3 A rating represents the maximum average rectified current the device can safely conduct. Exceeding this rating causes excessive heat generation and device failure. Verify actual circuit current requirements before substitution.

Q: What is the difference between Standard Recovery and Fast Recovery diodes?

A: Recovery speed refers to the time required for the diode to transition from conducting to blocking state. Standard Recovery (>500 ns) and Fast Recovery (≤500 ns) diodes both function identically in DC rectification applications. Recovery speed becomes significant in high-frequency switching circuits. For DC applications, both types are electrically compatible with the SMLJ60S2-TP.

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

A: All listed substitutes use the DO-214AB (SMC) surface mount package, identical to the SMLJ60S2-TP. Packaging variations exist only in tape format: some parts are supplied in Tape & Reel (TR), others in Cut Tape (CT) & Digi-Reel®. Verify packaging format compatibility with your assembly equipment before procurement.

Q: Why do some substitutes have higher maximum junction temperatures?

A: MURS320-13-F and MURS320T3G support Tj (Max) of 175°C compared to 150°C for the SMLJ60S2-TP. Higher temperature ratings indicate enhanced thermal capability but do not affect electrical performance at standard operating conditions. This specification is relevant only for applications operating at elevated ambient temperatures.

Q: Is the SMLJ60S2-TP still available for purchase?

A: The SMLJ60S2-TP is classified as "Not For New Designs" with 12,900 pcs in stock. This status indicates the manufacturer has discontinued active promotion and support. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. Active substitute parts are recommended for new production and future designs.

Q: What does ROHS3 compliance mean?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance certifies that the component meets European Union environmental standards, restricting the use of specific hazardous materials including lead, cadmium, and mercury. All listed substitute parts maintain ROHS3 compliance equivalent to the SMLJ60S2-TP.

Q: Can I substitute a 5 A rated diode for a 6 A application?

A: A 5 A rated diode can substitute for a 6 A application only when actual circuit current does not exceed 5 A. If your circuit requires the full 6 A capacity, a 5 A device will operate at or beyond its maximum rating, reducing reliability and lifespan. Confirm circuit current requirements before selecting a 5 A substitute.

Q: What is reverse leakage current and why does it vary among substitutes?

A: Reverse leakage current (Ir) is the small current that flows through a reverse-biased diode. The SMLJ60S2-TP specifies 5 µA @ 200 V. Substitutes range from 3 µA to 10 µA. Lower leakage current indicates better diode quality but does not affect circuit performance in most applications. Leakage current becomes significant only in high-impedance circuits or precision analog applications.
