Key Parameters

Substitute Part Grouping Explanation

Substitution of the DGS10-030A is determined by the following critical parameters:

Voltage Rating Compatibility: The substitute part must maintain a DC reverse voltage rating of 300 V or greater to ensure safe operation within the original circuit design envelope.

Current Rating Compatibility: The substitute part must support an average rectified current rating equal to or exceeding 11 A. Parts with higher current ratings provide design margin and are acceptable substitutes.

Package Compatibility: The substitute part must use the TO-220-2 package in Through Hole mounting configuration to ensure mechanical and thermal interface compatibility with existing PCB layouts and heatsinking arrangements.

Recovery Speed: The substitute part must maintain fast recovery characteristics (≤500 ns, >200 mA) to preserve circuit performance in high-frequency rectification applications.

Temperature Range: The substitute part must support the operating junction temperature range of -55°C to 175°C.

The SDUR1530 meets all substitution criteria with equivalent voltage and temperature ratings, superior current capacity (15 A versus 11 A), compatible package configuration, and matching fast recovery speed specification.

Frequently Asked Questions (FAQ)

Q: Can the SDUR1530 directly replace the DGS10-030A in existing designs?

A: Yes. Both parts share identical voltage ratings (300 V), compatible current capacity (SDUR1530 at 15 A exceeds DGS10-030A at 11 A), matching package configuration (TO-220-2), and equivalent operating temperature ranges (-55°C to 175°C). No circuit modifications are required.

Q: What are the key differences between these two diodes?

A: The primary differences are technology type (DGS10-030A is Schottky; SDUR1530 is Standard), forward voltage characteristics (DGS10-030A: 2 V @ 5 A; SDUR1530: 1.26 V @ 15 A), reverse leakage current (DGS10-030A: 1.3 mA @ 300 V; SDUR1530: 10 µA @ 300 V), and product status (DGS10-030A is Obsolete; SDUR1530 is Active). The SDUR1530 provides specified reverse recovery time (45 ns) not listed for the DGS10-030A.

Q: Are there thermal management considerations when substituting these parts?

A: Both parts use the TO-220-2 package and support identical operating temperature ranges. Thermal interface requirements remain unchanged. The SDUR1530's higher current rating (15 A versus 11 A) provides additional thermal margin in the application.

Q: What is the impact of the different forward voltage specifications?

A: The SDUR1530 exhibits lower forward voltage (1.26 V @ 15 A) compared to the DGS10-030A (2 V @ 5 A). This results in reduced power dissipation and improved efficiency in rectification circuits. Circuit designs based on the DGS10-030A forward voltage characteristics will experience improved performance with the SDUR1530.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts carry EAR99 export classification and HTSUS code 8541.10.0080. The SDUR1530 is RoHS3 Compliant and REACH Affected, meeting current regulatory requirements. The DGS10-030A is REACH Unaffected due to its obsolete status. For new designs and ongoing production, the SDUR1530 provides current regulatory compliance.

Q: What is the significance of the reverse recovery time specification for the SDUR1530?

A: The SDUR1530 specifies a reverse recovery time (trr) of 45 ns, indicating the time required for the diode to transition from forward conduction to reverse blocking. This specification is not provided for the DGS10-030A. The 45 ns value confirms fast recovery operation suitable for high-frequency rectification applications.

Q: How does the reverse leakage current difference affect circuit design?

A: The SDUR1530 exhibits significantly lower reverse leakage current (10 µA @ 300 V) compared to the DGS10-030A (1.3 mA @ 300 V). Lower leakage current reduces standby power consumption and improves circuit efficiency, particularly in applications with extended idle periods or high-impedance circuits.
