Engineering Selection Recommendations

Primary Substitute (Direct Replacement): GBPC3502 (SMC Diode Solutions) is the recommended primary substitute. It maintains identical electrical specifications to the GBPC3502/1, including 200 V peak reverse voltage, 35 A average rectified current, and QC Terminal mounting. The part is in active production status and ROHS3 compliant, addressing the obsolescence and compliance limitations of the original part.

Secondary Substitutes (Voltage Derating): GBPC3504 (Fairchild Semiconductor) and GBPC3510 (Taiwan Semiconductor Corporation) are suitable for applications where higher voltage margins are acceptable. GBPC3504 maintains the 35 A current rating with 400 V voltage capability and QC Terminal mounting. GBPC3510 provides 1 kV voltage rating with 35 A current but uses Chassis Mount configuration instead of QC Terminal.

Derating Substitutes (Current Reduction): GBPC2510, GBPC2504, GBPC2501, GBPC1504, GBPC1502, and GBPC1202 are suitable only for applications where the required current is lower than 35 A. These parts maintain the standard bridge rectifier technology and GBPC package family but with reduced current ratings. Selection depends on the actual circuit current requirements and voltage specifications.

Compliance Considerations: The original GBPC3502/1 is RoHS non-compliant. GBPC3502, GBPC3510, GBPC2510, GBPC2504, GBPC2501, and GBPC1504 are ROHS3 compliant, making them suitable for applications with RoHS compliance requirements. GBPC1502 is marked "Not For New Designs," limiting its use to legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can GBPC3502 directly replace GBPC3502/1? A: Yes. GBPC3502 (SMC Diode Solutions) is a direct electrical equivalent with identical voltage, current, and forward voltage specifications. Both use QC Terminal mounting and 4-Square GBPC packaging. The primary difference is product status—GBPC3502/1 is obsolete while GBPC3502 is in active production.

Q: What is the difference between QC Terminal and Chassis Mount configurations? A: QC Terminal mounting uses quick-connect terminals for panel-mount applications, while Chassis Mount uses screw terminals for direct chassis attachment. These are mechanically incompatible and require different PCB or mounting hardware designs.

Q: Can I use GBPC3510 as a substitute if my application only requires 200 V? A: Yes, GBPC3510 is electrically compatible for 200 V applications. It is rated for 1 kV peak reverse voltage, providing additional voltage margin. However, the Chassis Mount configuration differs from the QC Terminal mounting of GBPC3502/1, requiring mechanical redesign.

Q: What does "Not For New Designs" mean for GBPC1502? A: This designation indicates the part is available for legacy system support and repairs but should not be selected for new product development. onsemi recommends alternative parts for new designs.

Q: Can I use lower current-rated parts like GBPC1502 or GBPC2504? A: Lower current-rated substitutes are suitable only if your application requires less than 35 A average rectified current. Using an undersized part for higher current applications will cause overheating and failure. Verify actual circuit current requirements before selecting a derating substitute.

Q: Are all substitute parts RoHS compliant? A: No. GBPC3502/1 is RoHS non-compliant. GBPC3502, GBPC3510, GBPC2510, GBPC2504, GBPC2501, and GBPC1504 are ROHS3 compliant. GBPC3504 and GBPC1202 compliance status is not specified in the provided data.

Q: What is the significance of forward voltage (Vf) specifications? A: Forward voltage determines power dissipation and heat generation. All listed parts maintain 1.1 V maximum forward voltage at their respective rated currents, ensuring thermal performance consistency within the GBPC family.
