DFB2510 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DFB2510 is a single-phase bridge rectifier manufactured by onsemi, rated for 100 V peak reverse voltage and 25 A average rectified current. This component is classified as "Not For New Designs," indicating it has been superseded in onsemi's product portfolio. Finding equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original part may be unavailable or where design flexibility permits component substitution within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution for the DFB2510 is determined by strict equivalence across the following critical parameters:

Voltage - Peak Reverse (Max): 100 V
Current - Average Rectified (Io): 25 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 25 A
Current - Reverse Leakage @ Vr: 10 µA @ 100 V
Operating Temperature Range: -55°C ~ 150°C (TJ)
Mounting Type: Through Hole
Diode Type: Single Phase
Technology: Standard

Substitute parts are grouped into two categories based on package compatibility and product status:

Category 1: Parametric Equivalents (Identical Package) Parts maintaining the TS-6P package configuration with all electrical parameters matching the DFB2510 specification.

Category 2: Similar Substitutes (Alternative Package) Parts meeting all electrical parameters but utilizing an alternative package form factor (4-ESIP vs. 4-SIP, TS-6P).

Engineering Selection Recommendations

TS25P02G and TS25P02GH (Preferred Substitutes)

Both Taiwan Semiconductor parts are parametric equivalents with active product status and identical TS-6P package configuration. TS25P02G is suitable for general applications. TS25P02GH includes automotive-grade qualification (AEC-Q101) and is appropriate for automotive and high-reliability applications requiring enhanced qualification documentation.

GBJ2501 (Alternative Substitute)

The SMC Diode Solutions GBJ2501 meets all electrical parameters but uses a 4-ESIP package instead of the TS-6P configuration. This part is suitable only when PCB layout and mechanical mounting accommodate the alternative package form factor. Forward voltage specification is provided at 12.5 A rather than 25 A; verify thermal and operational conditions for your specific application circuit.

All substitute parts maintain ROHS3 compliance and the required operating temperature range of -55°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Can GBJ2501 be used as a direct replacement for DFB2510?

A: GBJ2501 meets all electrical specifications but uses a different package (4-ESIP vs. TS-6P). Direct PCB substitution is not possible without layout modification. Verify mechanical fit and pin configuration before selection.

Q: What is the difference between TS25P02G and TS25P02GH?

A: Both parts are electrically identical with the same TS-6P package. TS25P02GH includes automotive-grade qualification (AEC-Q101) and is specified for automotive applications. TS25P02G is suitable for industrial and general-purpose applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. DFB2510, GBJ2501, TS25P02G, and TS25P02GH are all ROHS3 compliant.

Q: Why is DFB2510 marked "Not For New Designs"?

A: This status indicates the part has been superseded by the manufacturer. Existing inventory remains available for legacy system support and repair. For new designs, select from active-status alternatives such as TS25P02G or TS25P02GH.

Q: Do all parts operate within the same temperature range?

A: Yes. All parts operate from -55°C to 150°C junction temperature, meeting the DFB2510 specification.
