STTH30L06CG Equivalent & Substitute Parts

Part Overview

The STTH30L06CG is a general-purpose diode array manufactured by STMicroelectronics, configured as 1 pair common cathode with 600 V reverse voltage rating and 20 A average rectified current per diode. The device is housed in a Surface Mount TO-263-3 D2PAK package with 2 leads plus tab. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The STTH30L06CG-TR and SDURB3060CT provide functional alternatives with identical or comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH30L06CG is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Diode configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 600 V
• Mounting type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Technology: Standard

Secondary Compatibility Parameters:

• Current - Average Rectified (Io) (per Diode): 20 A or higher
• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The STTH30L06CG-TR is a direct equivalent with identical electrical specifications and active product status. The SDURB3060CT is a functional substitute with the same package, voltage rating, and configuration, though with differing forward voltage and reverse recovery characteristics.

Parameter Comparison

Engineering Selection Recommendations

STTH30L06CG-TR (Primary Substitute)

The STTH30L06CG-TR is the preferred substitute for the obsolete STTH30L06CG. Both parts are manufactured by STMicroelectronics and share identical electrical specifications, including forward voltage, reverse recovery time, and reverse leakage current. The STTH30L06CG-TR maintains active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant with REACH Unaffected status. The only distinction is packaging format: STTH30L06CG-TR is supplied in Cut Tape (CT) and Digi-Reel® format, whereas the original part number does not specify packaging format. This substitute is suitable for direct replacement in all applications where the STTH30L06CG was originally specified.

SDURB3060CT (Alternative Substitute)

The SDURB3060CT, manufactured by SMC Diode Solutions, is a functional alternative that maintains the same 600 V reverse voltage rating, 1 pair common cathode configuration, and TO-263-3 D2PAK package. This part is active and ROHS3 compliant. However, the SDURB3060CT exhibits higher forward voltage (2.03 V @ 15 A versus 1.55 V @ 15 A), higher reverse leakage current (100 µA @ 600 V versus 15 µA @ 600 V), and a lower maximum junction temperature (150°C versus 175°C). The SDURB3060CT also carries REACH Affected status, whereas the original part is REACH Unaffected. The faster reverse recovery time (50 ns versus 85 ns) may provide benefits in specific switching applications. Selection of the SDURB3060CT requires verification that the higher forward voltage drop and reverse leakage current are acceptable within the target circuit design.

Frequently Asked Questions (FAQ)

Q: Can the STTH30L06CG-TR be used as a direct replacement for the STTH30L06CG?

A: Yes. The STTH30L06CG-TR is electrically and mechanically identical to the STTH30L06CG. Both parts feature the same 600 V reverse voltage rating, 20 A average rectified current, 1.55 V forward voltage at 15 A, 85 ns reverse recovery time, and TO-263-3 D2PAK package. The STTH30L06CG-TR is active and recommended for new designs and replacement procurement.

Q: What are the key differences between the STTH30L06CG and SDURB3060CT?

A: Both parts share the same 600 V reverse voltage rating, 1 pair common cathode configuration, and TO-263-3 D2PAK package. The SDURB3060CT differs in forward voltage (2.03 V versus 1.55 V at 15 A), reverse leakage current (100 µA versus 15 µA at 600 V), maximum junction temperature (150°C versus 175°C), and reverse recovery time (50 ns versus 85 ns). The SDURB3060CT also carries REACH Affected status.

Q: Is the SDURB3060CT suitable for all applications where the STTH30L06CG was used?

A: The SDURB3060CT is mechanically compatible and shares the same voltage rating and package. However, the higher forward voltage drop and reverse leakage current may affect circuit performance, particularly in low-loss or precision applications. The lower maximum junction temperature may also limit operation in high-temperature environments. Application-specific evaluation is required.

Q: Are all three parts RoHS compliant?

A: Yes. The STTH30L06CG, STTH30L06CG-TR, and SDURB3060CT are all ROHS3 compliant. However, the SDURB3060CT carries REACH Affected status, whereas the STMicroelectronics parts are REACH Unaffected.

Q: What is the difference between the STTH30L06CG and STTH30L06CG-TR packaging?

A: The STTH30L06CG-TR is supplied in Cut Tape (CT) and Digi-Reel® packaging format. Both parts use the same TO-263-3 D2PAK physical package. The packaging format difference affects handling and automated assembly compatibility but does not alter electrical or mechanical specifications.

Q: Can the STTH30L06CG be used in high-temperature applications?

A: The STTH30L06CG supports a maximum junction temperature of 175°C. The STTH30L06CG-TR maintains the same 175°C rating. The SDURB3060CT is limited to 150°C maximum junction temperature. Application requirements must be evaluated against these thermal specifications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts—STTH30L06CG, STTH30L06CG-TR, and SDURB3060CT—have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no moisture sensitivity constraints.
