GBPC35005 Bridge Rectifier Diode Equivalent & Substitute Parts

Part Overview

The GBPC35005 is a single-phase bridge rectifier diode manufactured by Diodes Incorporated, rated for 50 V peak reverse voltage and 35 A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new production alternatives. The GBPC35005 features a standard technology platform with QC terminal mounting and is ROHS3 compliant.

Substitute Part Grouping Explanation

Substitution for the GBPC35005 is determined by the following critical parameters:

Voltage Rating (Peak Reverse): 50 V minimum requirement
Current Rating (Average Rectified): 35 A minimum requirement
Diode Type: Single Phase
Technology: Standard
Mounting Type: QC Terminal or compatible
Package: 4-Square GBPC or equivalent form factor

Substitute parts are grouped into two categories:

Direct Equivalents maintain identical electrical specifications (50 V, 35 A) with the same package and mounting configuration.

Functional Alternatives meet or exceed the current rating (35 A or higher) at the same voltage rating (50 V), with compatible mounting and package specifications. These parts can replace the GBPC35005 in applications where higher current capacity is acceptable.

Engineering Selection Recommendations

Primary Direct Equivalent: GBPC35005-E4/51 (Vishay General Semiconductor) is the recommended direct substitute. This part maintains identical electrical specifications and package configuration with active product status. The operating temperature minimum is -55°C versus -65°C for the original part; verify application requirements if operation below -55°C is required.

Higher Current Alternative: BR50005-G (Comchip Technology) provides 50 A current capacity at 50 V, exceeding the GBPC35005 requirement. This part is suitable for applications where additional current margin is beneficial. Operating temperature range is -55°C to 125°C; verify upper temperature limit compatibility.

Lower Current Alternatives: GBPC25005 (25 A) and GBPC15005 (15 A) are suitable only for applications where the actual load current is below 35 A. These parts are not recommended as direct replacements for designs requiring the full 35 A capacity.

Voltage-Rated Alternatives: GBPC3502 (200 V, 35 A) is applicable only in applications where higher voltage rating is required or acceptable. This part is not a substitute for 50 V applications.

All recommended substitutes maintain ROHS3 compliance and standard bridge rectifier technology specifications.

Frequently Asked Questions (FAQ)

Q: Can GBPC35005-E4/51 replace GBPC35005 in all applications?

A: GBPC35005-E4/51 is electrically and mechanically compatible with identical 50 V and 35 A ratings. The operating temperature minimum is -55°C instead of -65°C. Verify that your application does not require operation below -55°C.

Q: Is BR50005-G a suitable replacement for GBPC35005?

A: BR50005-G can replace GBPC35005 in applications where 35 A or less is required. The part provides 50 A capacity at 50 V with compatible QC terminal mounting. Operating temperature range is -55°C to 125°C; confirm upper temperature limit compatibility with your design.

Q: Why are GBPC25005 and GBPC15005 listed as alternatives?

A: These parts share the same 50 V voltage rating and QC terminal package. They are suitable only for applications where actual load current is below their respective ratings (25 A and 15 A). They cannot replace GBPC35005 in designs requiring the full 35 A capacity.

Q: What is the difference between QC Terminal and Chassis Mount packages?

A: QC Terminal and Chassis Mount are different mechanical mounting configurations. Parts with different mounting types are not interchangeable without mechanical redesign. GBPC35005 uses QC Terminal mounting.

Q: Are all substitute parts ROHS3 compliant?

A: GBPC35005-E4/51, BR50005-G, GBPC25005, GBPC15005, and GBPC3502 are all ROHS3 compliant. GBPC12005 is ROHS3 compliant but marked as Not For New Designs.

Q: Can I use GBPC3502 (200 V) instead of GBPC35005 (50 V)?

A: GBPC3502 is rated for 200 V peak reverse voltage, which exceeds the 50 V requirement. This part can be used in 50 V applications; however, it is not a cost-effective substitute and should only be selected if higher voltage rating is required by the system design.
