Key Parameters

Substitute Part Grouping Explanation

Substitution of the DGSS20-06CC is evaluated based on the following critical parameters that define functional equivalence:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Series Connection
• Voltage - DC Reverse (Vr) (Max): 600 V
• Mounting Type: Through Hole
• Package / Case: ISOPLUS220™
• Operating Temperature - Junction: -55°C ~ 175°C

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitute must meet or exceed the original specification
• Technology: Substitutes may employ different diode technologies (Schottky or Standard) provided all electrical parameters remain within acceptable ranges
• Voltage - Forward (Vf): Substitutes must not exceed the original forward voltage specification at rated current
• Reverse Recovery Time (trr): Substitutes may vary within fast recovery classification

The DSEE29-12CC qualifies as a substitute based on matching the mandatory parameters. However, the current rating is reduced from 38 A to 30 A, which represents a design trade-off requiring circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

DSEE29-12CC as Substitute for DGSS20-06CC:

The DSEE29-12CC is an active product manufactured by IXYS and qualifies as a functional substitute based on matching package, configuration, voltage rating, and temperature range specifications. The substitute offers the following advantages:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance provides regulatory alignment for new designs and manufacturing environments
• Identical ISOPLUS220™ package and through-hole mounting enable direct mechanical replacement
• Matching 600 V voltage rating and -55°C to 175°C operating range maintain circuit voltage and thermal specifications

Design Consideration:

The current rating reduction from 38 A to 30 A requires circuit-level thermal and current distribution analysis. Applications operating at or near the original 38 A specification must confirm that the 30 A rating of the substitute is acceptable for the intended load profile. The lower forward voltage (1.62 V @ 30 A versus 2.1 V @ 20 A) of the substitute may reduce power dissipation in applications operating within the 30 A current envelope.

Frequently Asked Questions (FAQ)

Q: Can the DSEE29-12CC directly replace the DGSS20-06CC in all applications?

A: Direct mechanical and electrical replacement is possible due to identical package, configuration, voltage rating, and temperature range. However, the reduced current rating (30 A versus 38 A) requires verification that circuit operating currents remain within the substitute's specification. Thermal analysis of the application is necessary to confirm suitability.

Q: What is the primary difference between the DGSS20-06CC and DSEE29-12CC?

A: The primary differences are current rating (38 A versus 30 A), diode technology (Schottky versus Standard), and product status (Obsolete versus Active). Both devices share identical voltage ratings, package format, and operating temperature range.

Q: Why does the DSEE29-12CC have a lower forward voltage than the DGSS20-06CC?

A: Forward voltage is specified at different current levels: DGSS20-06CC at 2.1 V @ 20 A and DSEE29-12CC at 1.62 V @ 30 A. The comparison reflects the different measurement conditions and diode technology employed in each device.

Q: Is the ISOPLUS220™ package identical between both parts?

A: Yes. Both the DGSS20-06CC and DSEE29-12CC utilize the ISOPLUS220™ through-hole package, enabling direct mechanical substitution without PCB layout modifications.

Q: What compliance certifications apply to the DSEE29-12CC?

A: The DSEE29-12CC is ROHS3 compliant and carries REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: How does the reverse recovery time difference affect circuit performance?

A: The DSEE29-12CC exhibits a reverse recovery time of 35 ns compared to 20 ns for the DGSS20-06CC. Both devices maintain fast recovery classification (≤ 500 ns). The longer recovery time of the substitute may introduce minor timing differences in high-frequency switching applications but remains within fast recovery parameters.
