Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH60W02CW is determined by the following critical parameters:

Mandatory Matching Criteria:

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

Allowable Variation Criteria:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 30 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Reverse Recovery Time (trr): Within fast recovery specification
• Current - Reverse Leakage @ Vr: Within acceptable leakage limits
• Operating Temperature - Junction: Equal to or greater than 175°C maximum

The three substitute parts identified—VS-60CPU02-N3, DSEK60-02A, and SDUR6020WT—satisfy the mandatory matching criteria and fall within allowable variation parameters for current rating and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

VS-60CPU02-N3 (Vishay General Semiconductor - Diodes Division)

This substitute provides the closest electrical match to the STTH60W02CW. The part maintains identical voltage rating (200 V), current rating (30 A), and reverse recovery time (30 ns). Forward voltage is marginally lower at 1.1 V versus 1.15 V. The device carries Active product status and ROHS3 compliance. Operating temperature maximum matches the original specification at 175°C. Reverse leakage current is elevated at 50 µA compared to 10 µA in the original part. This substitute is suitable for direct replacement in applications where the increased leakage current does not impact circuit performance.

DSEK60-02A (IXYS)

This substitute meets the mandatory voltage and configuration requirements with 200 V reverse rating and 1 Pair Common Cathode configuration. Current rating is higher at 34 A, providing margin above the 30 A requirement. Forward voltage is 1.1 V at 30 A. The device carries Active product status and ROHS3 compliance. Operating temperature maximum is reduced to 150°C, which is 25°C below the original specification. Reverse recovery time is 50 ns, compared to 30 ns in the original part. Reverse leakage current is significantly elevated at 200 µA. This substitute is applicable in applications where the reduced maximum junction temperature and increased leakage current are acceptable.

SDUR6020WT (SMC Diode Solutions)

This substitute meets voltage and configuration requirements with 200 V reverse rating and 1 Pair Common Cathode configuration. Current rating is not specified in available data. Forward voltage is 1.2 V at 30 A, representing a 0.05 V increase over the original specification. The device carries Active product status. Operating temperature maximum is 150°C, 25°C below the original specification. Reverse recovery time is 45 ns. Reverse leakage current matches the original at 10 µA. REACH Status is listed as Affected, indicating regulatory considerations for certain applications. This substitute is applicable where the unspecified current rating and reduced maximum junction temperature are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the VS-60CPU02-N3 be used as a direct replacement for the STTH60W02CW?

A: Yes. The VS-60CPU02-N3 maintains identical voltage rating (200 V), current rating (30 A), reverse recovery time (30 ns), and maximum junction temperature (175°C). The primary difference is elevated reverse leakage current at 50 µA versus 10 µA. Direct substitution is valid where this leakage increase does not compromise circuit specifications.

Q: What is the impact of the reduced maximum junction temperature in the DSEK60-02A and SDUR6020WT?

A: Both alternatives specify 150°C maximum junction temperature, compared to 175°C in the original STTH60W02CW. This 25°C reduction limits thermal headroom in high-temperature applications. Selection of these alternatives requires confirmation that circuit operating conditions maintain junction temperature below 150°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The STTH60W02CW, VS-60CPU02-N3, DSEK60-02A, and SDUR6020WT are all ROHS3 compliant. The SDUR6020WT carries REACH Affected status, which may require evaluation for specific regulatory jurisdictions.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage variations range from 1.1 V to 1.2 V across the substitute options, compared to 1.15 V in the original part. These differences impact power dissipation and voltage drop across the rectifier. Applications with tight voltage regulation requirements should evaluate the specific forward voltage of the selected substitute.

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

A: Reverse leakage current ranges from 10 µA to 200 µA across the available options. Higher leakage increases standby power consumption and heat generation. Applications with stringent leakage specifications should prioritize VS-60CPU02-N3 or SDUR6020WT, which maintain leakage at or near the original 10 µA specification.

Q: Are all substitute parts available in the same TO-247-3 package?

A: Yes. All substitute parts are packaged in TO-247-3 Through Hole configuration, ensuring mechanical and thermal compatibility with the original STTH60W02CW footprint.

Q: What is the difference between reverse recovery time specifications?

A: The original STTH60W02CW specifies 30 ns reverse recovery time. The VS-60CPU02-N3 matches this specification. The DSEK60-02A and SDUR6020WT specify 50 ns and 45 ns respectively. Longer recovery times may impact switching frequency performance in high-speed rectification applications.
