Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SDURF2060 are qualified based on the following criteria:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Mounting Type: Through Hole
• Package / Case: TO-220-2 Full Pack, Isolated Tab
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitutes must equal or exceed 20 A
• Voltage - Forward (Vf) (Max) @ If: Substitutes must not exceed the forward voltage specification at their rated current
• Reverse Recovery Time (trr): Substitutes must not exceed 500 ns
• Current - Reverse Leakage @ Vr: Substitutes must not exceed 10 µA @ 600 V
• Operating Temperature - Junction: Substitutes must support the full operational range or higher

The identified substitute parts meet the mandatory electrical and mechanical compatibility requirements for direct replacement in applications requiring 600 V, 20 A general-purpose rectification.

Parameter Comparison

Engineering Selection Recommendations

STTH8L06FP (STMicroelectronics): This substitute is suitable for applications where the current requirement does not exceed 8 A. The device maintains 600 V reverse voltage rating and TO-220-2 package compatibility. Forward voltage is lower at 1.3 V @ 8 A compared to the main part. Reverse recovery time is 105 ns, within the fast recovery classification. All compliance certifications (ROHS3, MSL 1) are met. Operating temperature range extends to 175°C maximum, providing thermal margin above the main part specification.

BYC5X-600PQ (WeEn Semiconductors): This substitute is suitable for applications where the current requirement does not exceed 5 A. The device maintains 600 V reverse voltage rating and TO-220-2 package compatibility. Reverse recovery time is 25 ns, the fastest among all listed parts. Forward voltage is 3.3 V @ 5 A. All compliance certifications (ROHS3, MSL 1) are met. Operating temperature range extends to 175°C maximum. Reverse leakage current is 10 µA @ 600 V, at the upper allowable limit.

Both substitutes are Active product status with full regulatory compliance. Selection between substitutes depends on circuit current requirements and thermal design constraints.

Frequently Asked Questions (FAQ)

Q: Can STTH8L06FP or BYC5X-600PQ be used as direct replacements for SDURF2060 in all applications?

A: No. Both substitute parts have lower current ratings (8 A and 5 A respectively) compared to the main part (20 A). Direct replacement is only valid in circuits where the actual operating current does not exceed the substitute part's current rating. Exceeding the rated current will result in device failure.

Q: What are the key electrical differences between the three parts?

A: The primary difference is current rating: SDURF2060 is rated for 20 A, STTH8L06FP for 8 A, and BYC5X-600PQ for 5 A. All three maintain 600 V reverse voltage. Forward voltage characteristics differ: SDURF2060 is 2 V @ 20 A, STTH8L06FP is 1.3 V @ 8 A, and BYC5X-600PQ is 3.3 V @ 5 A. Reverse recovery times vary: SDURF2060 is 50 ns, STTH8L06FP is 105 ns, and BYC5X-600PQ is 25 ns.

Q: Are all three parts mechanically compatible?

A: Yes. All three parts use TO-220-2 Full Pack with isolated tab configuration and through-hole mounting. Pinout and thermal interface are identical, allowing mechanical interchangeability in PCB layouts.

Q: Do all parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant, have MSL 1 (Unlimited) moisture sensitivity level, and are Active product status. SDURF2060 is REACH Affected; STTH8L06FP is REACH Unaffected; BYC5X-600PQ status is not specified in the provided data.

Q: Which substitute has the best reverse recovery time performance?

A: BYC5X-600PQ has the fastest reverse recovery time at 25 ns. SDURF2060 is 50 ns, and STTH8L06FP is 105 ns. Faster recovery time reduces switching losses in high-frequency applications.

Q: What is the temperature operating range for each part?

A: SDURF2060 operates from -55°C to 150°C. STTH8L06FP operates to a maximum of 175°C. BYC5X-600PQ operates from -65°C to 175°C. Both substitutes provide extended high-temperature capability.

Q: Can I use a lower-current substitute in a 20 A circuit?

A: No. Using a substitute with insufficient current rating will cause thermal stress and premature failure. The substitute must be rated for the actual circuit current or higher.
