DFB25100 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DFB25100 is a single-phase bridge rectifier manufactured by onsemi, rated for 1 kV peak reverse voltage and 25 A average rectified current. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent or substitute parts is necessary for maintenance, repair, and legacy system support where the original component is no longer readily available or when design flexibility permits alternative selections.

Substitute Part Grouping Explanation

Substitution eligibility for the DFB25100 is determined by the following critical parameters:

Voltage Rating: Peak reverse voltage must be 1 kV or higher
Current Rating: Average rectified current must be 25 A or higher
Diode Type: Single-phase bridge rectifier configuration
Technology: Standard rectifier technology
Mounting Type: Through-hole construction
Operating Temperature: Range must encompass -55°C to 150°C
Regulatory Compliance: ROHS3 compliance required

Substitute parts are grouped into two categories:

Parametric Equivalents (TS25P07G, TS25P07GH): Identical electrical specifications and package type (TS-6P), maintaining full form-factor and functional compatibility.

Similar Substitutes (GBJ2510, GBJ3510-BP): Alternative package types (GBJ) with matching or superior electrical ratings. These require mechanical evaluation for mounting compatibility but provide electrical equivalence or enhancement.

Engineering Selection Recommendations

Direct Replacement (Preferred for Legacy Support):

TS25P07G and TS25P07GH are direct parametric equivalents with identical TS-6P packaging. Both are active products with full ROHS3 compliance. TS25P07GH includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability.

Alternative Substitutes (Requires Mechanical Evaluation):

GBJ2510 and GBJ3510-BP use alternative GBJ packaging. Both maintain the required 1 kV voltage rating and 25 A minimum current rating. GBJ3510-BP provides 35 A current capacity, offering design margin above the DFB25100 specification. Mechanical compatibility with existing PCB footprints and mounting hardware must be confirmed before selection.

All substitute parts maintain ROHS3 compliance and the required operating temperature range, ensuring regulatory and thermal compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can TS25P07G and TS25P07GH be used interchangeably with DFB25100?

A: Yes. Both parts share identical electrical specifications (1 kV, 25 A) and TS-6P packaging. TS25P07GH includes AEC-Q101 automotive qualification; TS25P07G does not. Selection depends on application requirements.

Q: What is the difference between TS-6P and GBJ packages?

A: TS-6P and GBJ are distinct through-hole package types with different physical dimensions and pin configurations. Direct mechanical compatibility cannot be assumed. PCB footprint verification is required before substituting GBJ-packaged parts for TS-6P applications.

Q: Can GBJ3510-BP replace DFB25100 in all applications?

A: GBJ3510-BP meets the minimum electrical requirements (1 kV, 25 A) and exceeds them (35 A capacity). However, the GBJ package differs from TS-6P. Mechanical compatibility with the existing PCB layout and mounting structure must be confirmed.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TS25P07G, TS25P07GH, GBJ2510, GBJ3510-BP) are ROHS3 compliant, matching the compliance status of the DFB25100.

Q: What is the operating temperature range for all parts?

A: All parts, including DFB25100 and all substitutes, operate across -55°C to 150°C (TJ), ensuring thermal compatibility in equivalent applications.
