DGS10-025A Equivalent & Substitute Parts

Part Overview

The DGS10-025A is a Schottky diode rated for 250 V DC reverse voltage and 12 A average rectified current in a Through Hole TO-220AC package. Manufactured by IXYS, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DGS10-025A is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 250 V
• Mounting Type: Must be Through Hole
• Package / Case: Must be TO-220-2 or compatible TO-220AC variant
• Speed: Must support Fast Recovery ≤ 500ns, > 200mA (Io)

Current Rating Consideration:

• Current - Average Rectified (Io): Substitute parts may exceed the 12 A rating of the main part, as higher current ratings provide design margin and are electrically compatible in applications requiring 12 A or less

Technology Consideration:

• Schottky technology is preferred for direct substitution due to forward voltage characteristics; however, standard rectifier diodes with compatible voltage and current ratings are acceptable substitutes when thermal and efficiency requirements permit

The substitute parts listed below satisfy these criteria within the allowed electrical and mechanical parameters for this product category.

Parameter Comparison

Engineering Selection Recommendations

MBR40250G (onsemi): This substitute is an active product with ROHS3 compliance and REACH unaffected status. The MBR40250G maintains the same 250 V reverse voltage rating and Schottky technology as the DGS10-025A. The 40 A current rating exceeds the 12 A requirement, providing design margin. The lower forward voltage (970 mV @ 40 A) and faster reverse recovery time (35 ns) offer improved efficiency characteristics. The operating temperature range (-65°C ~ 150°C) is narrower at the upper limit compared to the main part. This substitute is suitable for applications where the reduced upper temperature limit is acceptable.

SDUR1530 (SMC Diode Solutions): This substitute is an active product with ROHS3 compliance. The SDUR1530 uses standard rectifier technology rather than Schottky, with a higher 300 V reverse voltage rating and 15 A current rating. The forward voltage (1.26 V @ 15 A) is lower than the main part. The operating temperature range (-55°C ~ 175°C) matches the DGS10-025A exactly. The REACH affected status indicates regulatory considerations for certain applications. This substitute is suitable for applications where standard rectifier technology is acceptable and the higher voltage rating provides additional margin.

Both substitutes meet the mandatory compatibility criteria of 250 V minimum reverse voltage, Through Hole mounting, TO-220-2 package, and Fast Recovery speed classification.

Frequently Asked Questions (FAQ)

Q: Can the MBR40250G replace the DGS10-025A in all applications?

A: The MBR40250G is electrically compatible with the DGS10-025A for applications requiring 12 A or less at 250 V. Both devices use Schottky technology and share the same package. The primary consideration is the reduced maximum operating junction temperature of the MBR40250G (150°C versus 175°C for the DGS10-025A). Applications operating near the upper temperature limit of the original design require thermal analysis to confirm compatibility.

Q: What is the difference between the Schottky MBR40250G and the standard rectifier SDUR1530?

A: The MBR40250G is a Schottky diode with lower forward voltage drop and faster switching characteristics, making it more efficient in high-frequency applications. The SDUR1530 is a standard rectifier diode with higher forward voltage but a higher reverse voltage rating (300 V). Selection depends on application requirements for efficiency, switching speed, and voltage margin.

Q: Are both substitutes available in the same package as the DGS10-025A?

A: Yes. Both the MBR40250G and SDUR1530 are Through Hole devices in the TO-220-2 package, which is compatible with the TO-220AC package of the DGS10-025A. No PCB layout modifications are required for mechanical substitution.

Q: What is the significance of the REACH affected status for the SDUR1530?

A: The REACH affected status indicates that the SDUR1530 contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Applications subject to REACH compliance requirements must account for this designation during component selection and supply chain management.

Q: Can I use the MBR40250G or SDUR1530 in a design originally specified for the DGS10-025A without circuit modifications?

A: Both substitutes are pin-compatible and electrically compatible for applications requiring 12 A at 250 V. No circuit modifications are required. However, thermal design and operating temperature limits must be verified against the specific application requirements, particularly for the MBR40250G due to its lower maximum junction temperature.

Q: Which substitute offers the best performance improvement over the DGS10-025A?

A: The MBR40250G provides improved efficiency through lower forward voltage and faster reverse recovery time (35 ns). The SDUR1530 provides higher voltage margin (300 V rating) and maintains the same operating temperature range as the original part. Selection depends on whether efficiency or voltage margin is the priority for the specific application.
