Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DFB2505 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution eligibility are:

• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 25 A
• Diode Type: Single Phase
• Technology: Standard
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Through Hole

Two substitute parts meet these criteria: the GBJ25005 (SMC Diode Solutions) and the TS25P01G (Taiwan Semiconductor Corporation). Both maintain identical electrical ratings and through-hole mounting compatibility, enabling direct functional replacement in applications requiring 50 V / 25 A single-phase bridge rectification.

Parameter Comparison

Engineering Selection Recommendations

The TS25P01G (Taiwan Semiconductor Corporation) provides the closest functional and mechanical match to the DFB2505. Both components share identical package designation (4-SIP, TS-6P), forward voltage characteristics at 25 A, and active product status, ensuring long-term availability and supply chain stability.

The GBJ25005 (SMC Diode Solutions) offers electrical equivalence with identical voltage and current ratings. However, the forward voltage specification is measured at 12.5 A rather than 25 A, and the package designation differs (4-ESIP versus TS-6P). The GBJ25005 maintains active product status and ROHS3 compliance, supporting applications where package footprint variation is acceptable.

Both substitute parts carry ROHS3 compliance and EAR99 ECCN classification, matching the regulatory profile of the original DFB2505.

Frequently Asked Questions (FAQ)

Q: Can the GBJ25005 directly replace the DFB2505 in existing PCB layouts?

A: The GBJ25005 uses a 4-ESIP package, while the DFB2505 uses 4-SIP, TS-6P. Physical footprint differences may require PCB modification. The TS25P01G maintains identical package designation and is recommended for direct board-level substitution.

Q: What is the significance of the forward voltage measurement difference in the GBJ25005?

A: The GBJ25005 specifies forward voltage at 12.5 A, while the DFB2505 and TS25P01G specify at 25 A. Both maintain the 1.1 V maximum rating, confirming electrical compatibility at the rated 25 A operating current.

Q: Are all three parts RoHS compliant?

A: Yes. The DFB2505, GBJ25005, and TS25P01G all carry ROHS3 Compliant status, meeting environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: Why is the DFB2505 marked "Not For New Designs"?

A: This designation indicates the component is in mature or end-of-life status from the manufacturer. The TS25P01G and GBJ25005, both with Active product status, are recommended for new circuit development and long-term production planning.

Q: Do all substitute parts support the same operating temperature range?

A: Yes. All three components operate across -55°C to 150°C (TJ), ensuring thermal compatibility in equivalent applications.
