GBU6D Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The GBU6D is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 200 V peak reverse voltage and 6 A average rectified current. This component is classified as Active product status and is RoHS Compliant. Bridge rectifiers in the GBU package category serve as full-wave rectification solutions in power supply circuits, converting AC voltage to DC voltage across a wide range of industrial and commercial applications.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required for assembly processes, or when inventory constraints necessitate sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GBU6D bridge rectifier is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage - Peak Reverse (Max): 200 V
• Diode Type: Single Phase
• Mounting Type: Through Hole
• Package / Case: 4-SIP, GBU or equivalent GBU package variant
• Technology: Standard

Secondary Compatibility Factors:

• Current - Average Rectified (Io): 6 A nominal rating
• Voltage - Forward (Vf) (Max) @ If: Maximum 1.1 V @ 6 A
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Parts meeting all primary criteria are classified as direct electrical equivalents. Variations in packaging format (Bulk, Tube, Box) do not affect electrical compatibility but impact procurement and assembly workflows. Parts with identical electrical specifications but different forward voltage characteristics at alternative current levels or reduced average rectified current ratings require application-level verification of thermal and performance margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalence):

GBU602 (SMC Diode Solutions) and GBU602-G (Comchip Technology) are direct electrical equivalents to the GBU6D. Both parts maintain identical voltage and current ratings, reverse leakage characteristics, and operating temperature ranges. GBU602 is packaged in Tube format with 4-ESIP case designation, while GBU602-G is supplied in Bulk packaging with 4-SIP, GBU case. Both manufacturers hold Active product status and maintain ROHS3 compliance. Selection between these options depends on procurement packaging requirements and assembly process compatibility.

Secondary Substitute (Reduced Current Rating):

GBU6D (Diotec Semiconductor) shares the same part number designation but differs in average rectified current specification (4.2 A versus 6 A). This part maintains 200 V peak reverse voltage and identical reverse leakage characteristics. Operating temperature range is -50°C to 150°C, providing a 5°C reduction at the lower temperature limit compared to the primary part. RoHS status is listed as Not applicable. This substitute is suitable only for applications where the 4.2 A current rating satisfies thermal and load requirements.

Discontinued/Legacy Substitute (Not For New Designs):

GBU6D-BP (Micro Commercial Co) is designated as Not For New Designs. While electrical specifications match the primary GBU6D (6 A rating, 200 V, -55°C to 150°C), this product status classification indicates manufacturer discontinuation or transition planning. This part is available in existing inventory but should not be selected for new circuit designs or long-term production commitments.

Compliance Considerations:

The primary GBU6D (GeneSiC) holds RoHS Compliant status. Substitute parts GBU602, GBU602-G, and GBU6D-BP all maintain ROHS3 Compliant certification, ensuring regulatory alignment for applications subject to RoHS directives. The Diotec GBU6D variant lists RoHS status as Not applicable, requiring verification against specific application compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can GBU602 replace GBU6D in existing circuit designs?

A: Yes. GBU602 (SMC Diode Solutions) is a direct electrical equivalent with identical voltage (200 V), current (6 A), forward voltage (1.1 V @ 6 A), reverse leakage (5 µA @ 200 V), and operating temperature range (-55°C to 150°C). The primary difference is packaging format (Tube with 4-ESIP case versus Bulk with 4-SIP, GBU case). Mechanical fit and assembly process compatibility must be verified for the specific application.

Q: What is the difference between GBU602-G and GBU6D?

A: GBU602-G (Comchip Technology) matches the GBU6D in voltage (200 V), current (6 A), reverse leakage (5 µA @ 200 V), and operating temperature (-55°C to 150°C). Forward voltage specification differs: GBU602-G is rated 1 V @ 3 A, while GBU6D is rated 1.1 V @ 6 A. Both are packaged in 4-SIP, GBU format. GBU602-G is supplied in Bulk packaging, matching the primary GBU6D packaging format.

Q: Why does the Diotec GBU6D have a lower current rating (4.2 A)?

A: The Diotec GBU6D variant is rated for 4.2 A average rectified current, compared to 6 A for the primary GBU6D. This represents a different product variant within the GBU6D designation. This part is suitable only for applications where the reduced current rating satisfies thermal and load requirements. The 200 V voltage rating and reverse leakage characteristics remain identical.

Q: Is GBU6D-BP suitable for new product designs?

A: No. GBU6D-BP (Micro Commercial Co) is designated as Not For New Designs. While electrical specifications are compatible with the primary GBU6D, this product status indicates manufacturer discontinuation or transition planning. This part should be used only for legacy system maintenance or repair applications where existing inventory is available.

Q: What packaging formats are available for GBU6D equivalents?

A: The GBU6D and equivalent parts are available in three packaging formats: Bulk (GeneSiC GBU6D, Comchip GBU602-G), Tube (SMC GBU602, MCC GBU6D-BP), and Box (Diotec GBU6D). Packaging format affects procurement, storage, and assembly processes but does not impact electrical performance. Selection depends on assembly line requirements and inventory management practices.

Q: Are all substitute parts RoHS compliant?

A: The primary GBU6D (GeneSiC) is RoHS Compliant. Substitute parts GBU602, GBU602-G, and GBU6D-BP are ROHS3 Compliant, meeting current RoHS directive requirements. The Diotec GBU6D variant lists RoHS status as Not applicable. Applications subject to RoHS regulations should select parts with explicit RoHS compliance certification.

Q: What is the difference between 4-SIP and 4-ESIP package designations?

A: Both 4-SIP (Single In-line Package) and 4-ESIP (Enhanced Single In-line Package) are through-hole package formats for bridge rectifiers. The GBU6D uses 4-SIP, GBU designation, while GBU602 uses 4-ESIP. These designations reflect minor physical variations in lead configuration and spacing. Mechanical compatibility with PCB footprints must be verified before substitution.

Q: Can forward voltage differences affect circuit performance?

A: Forward voltage specifications are provided at specific current levels. GBU6D is rated 1.1 V @ 6 A, while GBU602-G and GBU6D-BP are rated 1 V @ 3 A. These measurements reflect different operating points and do not directly indicate performance differences at full 6 A operation. Application-level thermal and voltage drop analysis is required to assess impact on specific circuit designs.
