DGS20-025A Equivalent & Substitute Parts

Part Overview

The DGS20-025A is a Schottky rectifier diode rated for 250 V DC reverse voltage and 18 A average rectified current in a Through Hole TO-220AC package. This component is classified as Obsolete, making identification of suitable substitute parts necessary for ongoing design support and procurement continuity. The part features fast recovery characteristics with a maximum forward voltage of 1.5 V at 7.5 A and operates across a junction temperature range of -55°C to 175°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DGS20-025A is based on the following critical electrical and mechanical parameters:

Mandatory Matching Criteria:

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

Current Rating Consideration: The DGS20-025A is rated for 18 A average rectified current. Substitute parts with equal or higher current ratings maintain backward compatibility while providing equivalent or improved performance within the same voltage class and package footprint.

The MBR40250G meets all mandatory matching criteria with a 250 V reverse voltage rating, Schottky technology, Through Hole mounting, TO-220-2 package, and fast recovery speed specification. The MBR40250G provides a higher current rating of 40 A, which is acceptable for applications requiring the DGS20-025A's 18 A specification.

Parameter Comparison

Engineering Selection Recommendations

The MBR40250G is a direct substitute for the obsolete DGS20-025A based on electrical and mechanical compatibility. Both devices share identical reverse voltage ratings (250 V), Schottky technology, fast recovery speed characteristics, and TO-220-2 package specifications.

Product Status Advantage: The MBR40250G is classified as Active, ensuring long-term availability and continued manufacturing support, whereas the DGS20-025A is Obsolete.

Compliance and Certification: The MBR40250G carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts maintain REACH Unaffected status and share the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Current Rating: The MBR40250G's 40 A rating exceeds the DGS20-025A's 18 A specification, providing design margin and thermal headroom in applications operating at or below the original 18 A requirement.

Frequently Asked Questions (FAQ)

Q: Can the MBR40250G directly replace the DGS20-025A in existing designs?

A: Yes. Both devices share identical reverse voltage ratings (250 V), Schottky technology, fast recovery speed characteristics, and TO-220-2 package footprints. The MBR40250G's higher current rating (40 A versus 18 A) is compatible with applications designed for the DGS20-025A.

Q: What are the key electrical differences between these parts?

A: The primary differences are current rating (18 A versus 40 A), forward voltage characteristics (1.5 V @ 7.5 A versus 970 mV @ 40 A), reverse leakage current (2 mA @ 250 V versus 30 µA @ 250 V), and reverse recovery time (not specified versus 35 ns). The MBR40250G exhibits lower reverse leakage and specified reverse recovery time.

Q: Are the packages physically identical?

A: Both parts use TO-220-2 package specifications suitable for Through Hole mounting. The DGS20-025A is supplied as TO-220AC, and the MBR40250G is supplied as TO-220-2. These designations refer to the same physical package form factor with two leads.

Q: What is the operating temperature range difference?

A: The DGS20-025A operates from -55°C to 175°C junction temperature, while the MBR40250G operates from -65°C to 150°C. The MBR40250G provides lower minimum temperature operation but a lower maximum temperature limit.

Q: Why is the MBR40250G recommended over the DGS20-025A?

A: The MBR40250G is an Active product with current manufacturing support, whereas the DGS20-025A is Obsolete. The MBR40250G also carries ROHS3 compliance certification and provides improved reverse leakage characteristics and specified reverse recovery time.
