Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDURB1560 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variations:

• Current - Average Rectified (Io): Substitute parts may have rated current values equal to or greater than the application requirement
• Voltage - Forward (Vf) (Max) @ If: Substitute parts may have forward voltage specifications at different current ratings
• Reverse Recovery Time (trr): Substitute parts may have trr values within the fast recovery classification
• Current - Reverse Leakage @ Vr: Substitute parts may have leakage current values within acceptable operating ranges
• Operating Temperature - Junction (Max): Substitute parts may have higher maximum junction temperature ratings

The three substitute parts identified—VS-ETL1506S-M3, STTH806G-TR, and STTH12R06G—meet all mandatory matching criteria and fall within allowable parameter variations for the SDURB1560.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and MSL 1 rating, meeting the environmental and regulatory requirements of the SDURB1560.

VS-ETL1506S-M3 (Vishay General Semiconductor - Diodes Division): This part is rated for 15 A average rectified current with a forward voltage of 1.07 V @ 15 A, providing lower forward voltage drop compared to the SDURB1560. The reverse recovery time of 210 ns remains within the fast recovery classification. Operating temperature range extends to 175°C maximum junction temperature. This part is suitable for applications where lower forward voltage characteristics are beneficial for thermal management.

STTH806G-TR (STMicroelectronics): This part is rated for 8 A average rectified current with a forward voltage of 1.85 V @ 8 A. The reverse recovery time of 55 ns is comparable to the SDURB1560 at 50 ns. Operating temperature extends to 175°C maximum junction temperature. This part is suitable for applications with moderate current requirements and tight reverse recovery time specifications.

STTH12R06G (STMicroelectronics): This part is rated for 12 A average rectified current with a forward voltage of 2.9 V @ 12 A. The reverse recovery time of 45 ns is faster than the SDURB1560. Operating temperature extends to 175°C maximum junction temperature. This part is suitable for applications requiring higher current capacity with enhanced reverse recovery performance.

Selection among these substitutes depends on specific application current requirements, thermal constraints, and forward voltage drop considerations within the 600 V rating and D2PAK package format.

Frequently Asked Questions (FAQ)

Q: Can the VS-ETL1506S-M3 be used as a direct replacement for the SDURB1560?

A: The VS-ETL1506S-M3 meets all mandatory substitution criteria: 600 V reverse voltage rating, D2PAK surface mount package, fast recovery classification, ROHS3 compliance, and MSL 1 rating. The lower forward voltage (1.07 V @ 15 A versus 1.7 V @ 15 A) represents an operational advantage in power conversion efficiency. Substitution is valid within the specified electrical and mechanical parameters.

Q: What is the difference between the STTH806G-TR and STTH12R06G?

A: Both parts share the same 600 V reverse voltage rating, D2PAK package, and fast recovery classification. The primary differences are current rating (8 A versus 12 A) and forward voltage characteristics (1.85 V @ 8 A versus 2.9 V @ 12 A). The STTH12R06G provides higher current capacity with faster reverse recovery time (45 ns versus 55 ns). Selection depends on application current requirements and thermal design considerations.

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

A: All substitute parts use the TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package format, ensuring mechanical and thermal compatibility with the SDURB1560. Packaging variations exist in supplier delivery format (Tape & Reel, Cut Tape & Digi-Reel, Tube, or Bulk), but the component package itself remains identical.

Q: What is the significance of the reverse recovery time (trr) parameter?

A: Reverse recovery time indicates the speed at which the diode transitions from conducting to blocking state. All listed parts, including the SDURB1560, are classified as fast recovery diodes with trr ≤ 500 ns for currents > 200 mA. The SDURB1560 has trr of 50 ns, while substitutes range from 45 ns to 210 ns. Faster recovery times reduce switching losses in high-frequency applications.

Q: Can I use a substitute part with a higher maximum junction temperature rating?

A: Yes. The SDURB1560 is rated to 150°C maximum junction temperature, while all substitute parts are rated to 175°C. A higher temperature rating provides additional thermal margin and does not compromise functionality in applications operating within the SDURB1560 temperature range. The substitute part's higher rating represents an operational advantage.

Q: What does ROHS3 compliance mean for component substitution?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All listed parts are ROHS3 compliant, ensuring regulatory compatibility for applications subject to environmental and safety standards. Substitution between ROHS3-compliant parts maintains regulatory compliance.

Q: How does forward voltage affect component selection?

A: Forward voltage (Vf) determines the voltage drop across the diode during conduction. Lower forward voltage reduces power dissipation and heat generation. The VS-ETL1506S-M3 exhibits the lowest forward voltage (1.07 V @ 15 A), while the STTH12R06G exhibits the highest (2.9 V @ 12 A). Selection depends on thermal budget and efficiency requirements of the specific application.
