DPG60I400HA Equivalent & Substitute Parts

Part Overview

The DPG60I400HA is a general-purpose rectifier diode manufactured by IXYS, rated for 400 V DC reverse voltage and 60 A average rectified current. This through-hole component operates within the HiPerFRED™ series and is classified as a fast recovery diode with a reverse recovery time of 45 ns. The part is currently active in production and RoHS3 compliant.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified voltage and current ratings, while maintaining compatibility with through-hole mounting applications and meeting the same regulatory compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPG60I400HA is determined by the following critical parameters:

Primary Electrical Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 400 V
• Current - Average Rectified (Io): Must equal or exceed 60 A
• Speed Classification: Must maintain Fast Recovery characteristics (≤ 500ns, > 200mA)

Secondary Electrical Criteria:

• Voltage - Forward (Vf) (Max) @ If: Acceptable within component design tolerances
• Reverse Recovery Time (trr): Lower values indicate improved performance
• Current - Reverse Leakage @ Vr: Lower values indicate improved performance

Mechanical & Compliance Criteria:

• Mounting Type: Through Hole (required)
• Package / Case: TO-247-2 or DO-247-2 (compatible footprints)
• Operating Temperature - Junction: Minimum -40°C to maximum 175°C
• RoHS Status: ROHS3 Compliant (required)

Substitute parts STTH6004W and STTH60R04W meet the primary electrical criteria with matching 400 V and 60 A ratings. Part STTH30R04W is grouped separately due to reduced current rating (30 A versus 60 A), making it suitable only for applications with lower current requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (60 A Rating):

STTH6004W and STTH60R04W are functionally equivalent to the DPG60I400HA for applications requiring 60 A at 400 V. Both parts are manufactured by STMicroelectronics, carry active product status, and maintain ROHS3 compliance and REACH unaffected status. The primary difference between these two options and the original part lies in package configuration (DO-247-2 versus TO-247-2) and reverse recovery time characteristics. STTH6004W exhibits the lowest forward voltage drop (1.2 V @ 60 A) among the 60 A options, while STTH60R04W provides an intermediate reverse recovery time (80 ns) between the original part and STTH6004W.

Reduced Current Substitute (30 A Rating):

STTH30R04W is suitable only for applications where the circuit current requirement does not exceed 30 A. This part shares the 400 V voltage rating and fast recovery characteristics but is not interchangeable with the DPG60I400HA in circuits designed for 60 A operation.

Compliance Verification:

All substitute parts maintain RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can STTH6004W directly replace DPG60I400HA in a 60 A circuit?

A: STTH6004W meets the electrical requirements of 400 V and 60 A operation. The primary consideration is package compatibility. DPG60I400HA uses TO-247-2 packaging while STTH6004W uses DO-247-2 (Straight Leads). Both are through-hole packages with similar thermal and mechanical characteristics, but PCB layout and lead positioning must be verified for mechanical fit.

Q: What is the significance of the reverse recovery time difference between DPG60I400HA (45 ns) and the substitute parts?

A: The DPG60I400HA has a faster reverse recovery time (45 ns) compared to STTH6004W (90 ns) and STTH60R04W (80 ns). Faster recovery times reduce switching losses and electromagnetic interference in high-frequency applications. Applications operating at lower switching frequencies may not require this performance advantage.

Q: Is STTH30R04W suitable for a 60 A application?

A: No. STTH30R04W is rated for 30 A average rectified current and cannot be used in circuits designed for 60 A operation. Using an undersized component creates thermal stress and reliability risks.

Q: How do forward voltage drop differences affect circuit performance?

A: Forward voltage drop (Vf) directly impacts power dissipation and heat generation. STTH6004W exhibits 1.2 V @ 60 A compared to DPG60I400HA at 1.47 V @ 60 A. Lower forward voltage reduces power loss and thermal load, which may improve overall circuit efficiency.

Q: Are the DO-247-2 and TO-247-2 packages mechanically interchangeable?

A: Both packages are through-hole configurations with similar lead spacing and thermal characteristics. However, physical lead geometry and PCB footprint requirements differ. Mechanical compatibility must be confirmed through PCB layout verification before component substitution.

Q: Do all substitute parts meet the same regulatory requirements as the original DPG60I400HA?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity level, matching the regulatory status of the original component.

Q: What is the impact of higher reverse leakage current in substitute parts?

A: STTH6004W and STTH60R04W exhibit higher reverse leakage current (50 µA and 60 µA respectively) compared to DPG60I400HA (1 µA @ 400 V). Higher leakage increases standby power consumption and heat generation. Applications with stringent leakage requirements should evaluate this parameter against circuit specifications.
