Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STTH30AC06CWL is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Diode Configuration: 1 Pair Common Cathode
• Mounting Type: Through Hole
• Package / Case: TO-247-3
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Within acceptable circuit design margins
• Reverse Recovery Time (trr): Faster or equivalent performance
• Current - Reverse Leakage @ Vr: Within acceptable leakage specifications
• Operating Temperature - Junction: Minimum range must support application requirements

The SDUR3060WT from SMC Diode Solutions meets all critical matching parameters and is classified as an equivalent substitute for the STTH30AC06CWL.

Engineering Selection Recommendations

STTH30AC06CWL (Primary Component)

The STTH30AC06CWL remains the primary selection when available. This component is manufactured by STMicroelectronics, carries Active product status, and is ROHS3 compliant. The part demonstrates lower reverse leakage current (10 µA @ 600 V) and a wider operating temperature range (-65°C to 175°C), providing superior performance margins in temperature-sensitive applications.

SDUR3060WT (Substitute Component)

The SDUR3060WT from SMC Diode Solutions is qualified as an equivalent substitute when the STTH30AC06CWL is unavailable. This component satisfies all critical electrical and mechanical requirements: 600 V reverse voltage rating, 1 Pair Common Cathode configuration, Through Hole mounting, and TO-247-3 package compatibility. The substitute exhibits faster reverse recovery time (50 ns versus 55 ns), supporting high-frequency switching applications.

Selection Constraints:

The SDUR3060WT operates within a narrower temperature range (-55°C to 150°C) compared to the primary part. Applications requiring operation below -55°C or above 150°C must retain the STTH30AC06CWL. Additionally, the substitute exhibits higher reverse leakage current (100 µA @ 600 V versus 10 µA @ 600 V), which may impact performance in low-leakage or high-impedance circuit topologies. Both components are ROHS3 compliant and carry Active product status.

Frequently Asked Questions (FAQ)

Q: Can the SDUR3060WT directly replace the STTH30AC06CWL in all applications?

A: The SDUR3060WT is mechanically and electrically compatible for most applications. However, two constraints apply: (1) Operating temperature range is narrower (-55°C to 150°C versus -65°C to 175°C), and (2) Reverse leakage current is higher (100 µA @ 600 V versus 10 µA @ 600 V). Verify that your application operates within these limits before substitution.

Q: What is the significance of the reverse leakage current difference?

A: Reverse leakage current represents the small current flowing through the diode in reverse bias. The STTH30AC06CWL exhibits 10 µA @ 600 V, while the SDUR3060WT exhibits 100 µA @ 600 V. In high-impedance circuits or precision analog applications, this tenfold difference may affect circuit performance. In standard power rectification applications, this difference is typically negligible.

Q: Are both components pin-compatible?

A: Yes. Both the STTH30AC06CWL and SDUR3060WT use the TO-247-3 package with identical pin configuration and mechanical dimensions. Through Hole mounting is identical for both components.

Q: What is the difference between TO-247-3 and TO-247AD packaging?

A: The STTH30AC06CWL uses TO-247-3 package designation, while the SDUR3060WT uses TO-247AD supplier device package designation. Both refer to the same physical TO-247-3 package form factor with three leads. The designations reflect manufacturer-specific nomenclature but represent identical mechanical and electrical interfaces.

Q: Why is the average rectified current not specified for the SDUR3060WT?

A: The SDUR3060WT datasheet does not explicitly state the average rectified current per diode. However, the forward voltage specification (2.03 V @ 15 A) indicates operation at 15 A, consistent with the STTH30AC06CWL. Confirm with the manufacturer if current rating is critical for your application.

Q: Which component should I select for extreme temperature applications?

A: The STTH30AC06CWL supports -65°C to 175°C operation, while the SDUR3060WT supports -55°C to 150°C. For applications requiring operation below -55°C or above 150°C, the STTH30AC06CWL is mandatory.

Q: Are both components RoHS compliant?

A: Yes. Both the STTH30AC06CWL and SDUR3060WT are ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing.
