SDUR3030WT Equivalent & Substitute Parts

Part Overview

The SDUR3030WT is a general-purpose diode array manufactured by SMC Diode Solutions, configured as a 1 Pair Common Cathode rectifier with 300V reverse voltage rating and 15A average rectified current per diode. The device is packaged in TO-247-3 through-hole format and maintains Active product status with full RoHS3 compliance.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in circuit applications. Substitution becomes necessary due to inventory availability, supply chain optimization, or design flexibility requirements while maintaining functional equivalence within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SDUR3030WT are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for valid substitution:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 300 V minimum
• Package / Case: TO-247-3
• Mounting Type: Through Hole
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 15A
• Voltage - Forward (Vf) (Max): Within acceptable forward voltage range for rectifier applications
• Reverse Recovery Time (trr): Faster recovery times are acceptable
• Current - Reverse Leakage @ Vr: Lower leakage values are acceptable
• Operating Temperature - Junction: Extended temperature ranges are acceptable

The DPG80C300HB meets all critical matching parameters and exceeds current rating specifications, making it a valid substitute for applications where higher current capacity is acceptable or beneficial.

Engineering Selection Recommendations

SDUR3030WT Selection Criteria: The SDUR3030WT is appropriate for applications requiring 15A average rectified current at 300V reverse voltage with standard fast recovery diode performance. This part maintains Active product status and full RoHS3 compliance. Current inventory of 698 pieces supports immediate availability for production requirements.

DPG80C300HB Selection Criteria: The DPG80C300HB is appropriate as a substitute when higher current capacity (40A per diode) is required or preferred within the same 300V reverse voltage specification. This part also maintains Active product status and full RoHS3 compliance. The extended operating temperature range (-55°C to 175°C versus -55°C to 150°C) provides additional thermal margin. Faster reverse recovery time (35ns versus 45ns) and lower reverse leakage current (1µA versus 5µA) represent performance improvements. Current inventory of 2260 pieces supports high-volume production requirements. REACH Unaffected status may provide supply chain advantages in certain regulatory jurisdictions.

Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080, ensuring consistent export and tariff classification.

Frequently Asked Questions (FAQ)

Q: Can the DPG80C300HB directly replace the SDUR3030WT in existing circuit designs?

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), reverse voltage rating (300V), package format (TO-247-3), and fast recovery speed classification. The DPG80C300HB's higher current rating (40A versus 15A) and improved electrical characteristics (faster recovery time, lower leakage) are compatible with applications designed for the SDUR3030WT.

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

A: The primary difference is current capacity: SDUR3030WT is rated for 15A average rectified current per diode, while DPG80C300HB is rated for 40A. Secondary differences include forward voltage (1.25V @ 10A versus 1.36V @ 40A), reverse recovery time (45ns versus 35ns), and reverse leakage current (5µA versus 1µA). Operating temperature range extends from 150°C to 175°C maximum junction temperature.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SDUR3030WT and DPG80C300HB are RoHS3 compliant. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the significance of the TO-247-3 package format?

A: TO-247-3 is a through-hole package with three leads, standardized for high-current rectifier diodes. Both parts use identical TO-247AD supplier device packaging, ensuring mechanical and thermal compatibility in PCB layouts and thermal management designs.

Q: Does the DPG80C300HB's REACH Unaffected status affect substitution decisions?

A: REACH Unaffected status for the DPG80C300HB may provide supply chain advantages in European Union regulatory environments. The SDUR3030WT is REACH Affected. Both parts are functional equivalents; REACH status is a regulatory consideration rather than a technical compatibility factor.

Q: Can the SDUR3030WT be used in applications designed for the DPG80C300HB?

A: No. The SDUR3030WT's 15A current rating is lower than the DPG80C300HB's 40A rating. Applications designed for 40A operation would exceed the SDUR3030WT's current capacity, resulting in device failure or reduced reliability.
