S5J Equivalent & Substitute Parts Reference

Part Overview

The S5J is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as Active product status with standard recovery characteristics and operates across a junction temperature range of -55°C to 150°C. The S5J is RoHS3 compliant and REACH unaffected, making it suitable for applications requiring industrial-grade rectification in compact surface mount form factors. Equivalent and substitute parts are identified based on matching or exceeding electrical performance parameters within the same package category while maintaining functional compatibility in rectification applications.

Substitute Part Grouping Explanation

Substitute parts for the S5J are classified into two categories based on electrical parameter alignment:

Direct Equivalent (Same Current Rating): The S5J manufactured by Diotec Semiconductor maintains identical voltage (600 V) and current (5 A) ratings with matching package type (DO-214AB, SMC). This part provides direct functional substitution with equivalent electrical performance.

Similar Substitutes (Reduced Current Rating): The MURS360T3G (onsemi) and RS3J-13-F (Diodes Incorporated) are classified as similar substitutes due to reduced average rectified current (3 A versus 5 A). These parts maintain the 600 V voltage rating and DO-214AB package compatibility but operate at lower current capacity. Substitution is valid only in applications where the circuit current requirement does not exceed 3 A.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 600 V
Package / Case: Must be DO-214AB or SMC equivalent
Mounting Type: Must be Surface Mount
Current - Average Rectified (Io): Must meet or exceed circuit requirement

Engineering Selection Recommendations

For Direct Substitution (Same Electrical Performance): The S5J manufactured by Diotec Semiconductor is the primary equivalent substitute. Both parts maintain identical voltage and current ratings with matching DO-214AB package specifications. The Diotec variant operates within a slightly narrower temperature range (-50°C to 150°C versus -55°C to 150°C). RoHS compliance status differs; the Diotec part lists "Not applicable" while the Taiwan Semiconductor version is ROHS3 compliant. REACH status for the Diotec part is listed as "Vendor Undefined," which may require clarification for applications subject to REACH regulations.

For Current-Limited Applications (3 A Maximum): The MURS360T3G (onsemi) and RS3J-13-F (Diodes Incorporated) are suitable substitutes only when circuit current requirements do not exceed 3 A. Both parts maintain the 600 V voltage rating and DO-214AB package compatibility. The MURS360T3G offers superior recovery characteristics (75 ns trr) and extended temperature range (-65°C to 175°C) with ROHS3 compliance and REACH unaffected status. The RS3J-13-F provides moderate recovery performance (250 ns trr) with ROHS3 compliance and REACH unaffected status, operating across -65°C to 150°C.

Compliance Considerations: All substitute parts except the Diotec S5J variant maintain explicit ROHS3 compliance and REACH unaffected status. Applications requiring documented regulatory compliance should prioritize the Taiwan Semiconductor S5J, MURS360T3G, or RS3J-13-F.

Frequently Asked Questions (FAQ)

Q: Can the MURS360T3G or RS3J-13-F replace the S5J in all applications?

A: No. These parts are suitable only in applications where the average rectified current requirement does not exceed 3 A. The S5J is rated for 5 A, while both similar substitutes are rated for 3 A. Circuit current exceeding 3 A requires the full 5 A rated part.

Q: What is the difference between the two S5J variants from Taiwan Semiconductor and Diotec?

A: Both maintain identical voltage (600 V) and current (5 A) ratings with matching DO-214AB packages and 1.5 µs reverse recovery time. The Taiwan Semiconductor version operates from -55°C to 150°C with ROHS3 compliance and REACH unaffected status. The Diotec version operates from -50°C to 150°C with undefined REACH status and non-applicable RoHS classification. The Taiwan Semiconductor variant is preferred for applications requiring documented regulatory compliance.

Q: Why do the MURS360T3G and RS3J-13-F have faster recovery times than the S5J?

A: The MURS360T3G and RS3J-13-F are classified as fast recovery diodes (≤500 ns) with reverse recovery times of 75 ns and 250 ns respectively, compared to the S5J standard recovery classification (>500 ns) with 1.5 µs trr. Faster recovery characteristics reduce switching losses in high-frequency applications but are not required for standard rectification circuits.

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

A: Yes. All parts listed use the DO-214AB (SMC) surface mount package. Packaging differences exist only in supplier delivery format: the Taiwan Semiconductor S5J and Diotec S5J are supplied in Tape & Reel (TR), while the MURS360T3G is supplied in Cut Tape (CT) & Digi-Reel®, and the RS3J-13-F is supplied in Tape & Reel (TR).

Q: Which substitute part offers the widest operating temperature range?

A: The MURS360T3G (onsemi) operates across -65°C to 175°C, providing the widest temperature range among all listed parts. The original S5J operates from -55°C to 150°C.

Q: What is the significance of reverse leakage current differences between parts?

A: Reverse leakage current affects power dissipation and circuit performance under reverse bias conditions. The S5J (Taiwan Semiconductor) and MURS360T3G specify 10 µA @ 600 V, while the RS3J-13-F specifies 5 µA @ 600 V, indicating lower leakage. The Diotec S5J specifies 10 µA @ 50 V, which is measured at a lower voltage and is not directly comparable to the 600 V specification of other parts.
