DPG60C400HB Equivalent & Substitute Parts

Part Overview

The DPG60C400HB is a general-purpose diode array manufactured by IXYS, configured as a 1 Pair Common Cathode rectifier with 400 V reverse voltage rating and 30 A average rectified current per diode. The device is housed in a TO-247-3 through-hole package and is part of the HiPerFRED™ series. This component is Active in product status and RoHS3 compliant.

Substitute parts are identified when equivalent or superior electrical and mechanical specifications are required due to inventory availability, application-specific performance needs, or design flexibility across manufacturing sources.

Substitute Part Grouping Explanation

Substitute parts for the DPG60C400HB are classified based on the following substitution criteria:

Parametric Equivalent Classification: Parts that maintain identical or functionally equivalent electrical specifications across all critical parameters including reverse voltage (400 V), average rectified current (30 A), forward voltage drop (1.41 V @ 30 A), reverse recovery time (45 ns), diode configuration (1 Pair Common Cathode), and package type (TO-247-3). These parts are direct functional replacements.

Similar/Upgraded Classification: Parts that maintain the same reverse voltage (400 V) and package type (TO-247-3) but feature enhanced current ratings (50 A vs. 30 A) or modified electrical characteristics. These parts are suitable for applications requiring higher current capacity within the same voltage and form factor constraints.

The following parameters determine substitution eligibility:

• Voltage - DC Reverse (Vr) (Max): 400 V (required match)
• Diode Configuration: 1 Pair Common Cathode (required match)
• Package / Case: TO-247-3 (required match)
• Mounting Type: Through Hole (required match)
• Current - Average Rectified (Io): 30 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) (required match)

Parameter Comparison

Engineering Selection Recommendations

DUR6040WT (Littelfuse Inc.): This part is a parametric equivalent to the DPG60C400HB, maintaining identical voltage, current, forward voltage drop, and reverse recovery time specifications. Both devices are Active in product status and RoHS3 compliant. The DUR6040WT operates across a temperature range of -55°C to 150°C, which is 25°C lower at the maximum junction temperature compared to the DPG60C400HB. Selection of this substitute is appropriate for applications where the lower maximum operating temperature is acceptable and Littelfuse sourcing is preferred.

STTH100W04CW (STMicroelectronics): This part is classified as a similar/upgraded substitute with enhanced current capacity (50 A vs. 30 A) while maintaining the same 400 V reverse voltage rating and TO-247-3 package. The reverse recovery time is 50 ns, which is 5 ns longer than the DPG60C400HB. The forward voltage drop is 1.45 V at 50 A, compared to 1.41 V at 30 A for the main part. Reverse leakage current is higher at 25 µA @ 400 V. This device is Active in product status and RoHS3 compliant. Selection of this substitute is appropriate for applications requiring higher current capacity within the same voltage and package constraints, provided the increased reverse leakage and slightly extended recovery time are acceptable.

All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can the DUR6040WT directly replace the DPG60C400HB in all applications?

A: The DUR6040WT is a parametric equivalent with identical electrical specifications for voltage, current, forward voltage drop, and reverse recovery time. Direct replacement is supported for applications operating within the DUR6040WT's maximum junction temperature of 150°C. Applications requiring operation above 150°C require verification against specific thermal requirements.

Q: What is the primary difference between the DPG60C400HB and STTH100W04CW?

A: The STTH100W04CW features a higher average rectified current rating of 50 A per diode compared to 30 A for the DPG60C400HB. Both maintain 400 V reverse voltage and TO-247-3 packaging. The STTH100W04CW exhibits higher reverse leakage current (25 µA vs. 1 µA @ 400 V) and a slightly longer reverse recovery time (50 ns vs. 45 ns). Selection depends on whether the application requires the higher current capacity and whether the increased leakage and recovery time are acceptable.

Q: Are all three parts compatible with the same PCB layout and thermal management design?

A: All three parts use the TO-247-3 package and through-hole mounting type, ensuring mechanical and electrical pin compatibility. PCB layout and thermal management designs developed for the DPG60C400HB are directly applicable to the DUR6040WT. The STTH100W04CW, while using the same package, may require thermal management review due to its higher current rating and increased reverse leakage current.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.10.0080. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for the DPG60C400HB and STTH100W04CW, indicating no moisture sensitivity constraints during storage and handling.

Q: Can the STTH100W04CW be used in a circuit designed for 30 A operation?

A: Yes. The STTH100W04CW is rated for 50 A average rectified current, making it suitable for circuits designed for lower current levels such as 30 A. The device will operate within its specifications at reduced current levels. However, the higher reverse leakage current (25 µA vs. 1 µA @ 400 V) should be evaluated for applications sensitive to leakage current performance.

Q: What is the significance of the 1 Pair Common Cathode configuration?

A: The 1 Pair Common Cathode configuration indicates that the diode array contains two diodes with a shared cathode terminal. This configuration is standard for bridge rectifier applications and dual-diode circuits. All three substitute parts maintain this identical configuration, ensuring functional compatibility in applications designed for this topology.
