BR66 Bridge Rectifier Single Phase 600V 6A Equivalent & Substitute Parts

Part Overview

The BR66 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 600V peak reverse voltage and 6A average rectified current. This component is classified as a standard technology diode in through-hole BR-6 package configuration and maintains Active product status. Bridge rectifiers of this specification are essential in AC-to-DC conversion applications requiring moderate voltage and current ratings. Substitute parts may be required due to inventory availability, supply chain considerations, or specific application compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the BR66 is determined by strict equivalence across the following critical parameters:

Voltage Rating: Peak reverse voltage must equal 600V to maintain circuit protection and component reliability.

Current Rating: Average rectified current must equal 6A to ensure proper load handling without thermal stress.

Diode Type: Single-phase configuration is required for compatibility with the intended rectification topology.

Technology Classification: Standard technology designation ensures consistent performance characteristics across the product family.

Mounting Type: Through-hole mounting is mandatory for mechanical and electrical compatibility with existing PCB designs.

Package Configuration: The 4-Square BR-6 package form factor must be maintained for physical fit and thermal management.

The PB66-BP manufactured by Micro Commercial Co meets all these substitution criteria and is therefore classified as an equivalent substitute for the BR66.

Engineering Selection Recommendations

BR66 (GeneSiC Semiconductor): This component is Active in product status and RoHS Compliant. It is suitable for applications requiring the specified voltage and current ratings with the -65°C to 125°C operating temperature range. Current inventory availability is 1112 pieces.

PB66-BP (Micro Commercial Co): This substitute component is also Active in product status and maintains ROHS3 Compliance with REACH Unaffected status. The PB66-BP offers an extended operating temperature range of -55°C to 150°C and higher inventory availability at 1912 pieces. The forward voltage specification is marginally higher at 1.1V versus 1V, which remains within acceptable tolerance for standard bridge rectifier applications. Both components share identical peak reverse voltage, average rectified current, and reverse leakage specifications.

Selection between these parts should be based on application-specific temperature requirements, compliance certifications needed for the end product, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the PB66-BP directly replace the BR66 in existing designs?

A: Yes. Both components share identical electrical ratings for voltage (600V), current (6A), and leakage characteristics (10µA @ 600V). The through-hole mounting and 4-Square package configuration are mechanically compatible. The forward voltage difference of 0.1V is within standard tolerance for bridge rectifier applications.

Q: What is the significance of the different operating temperature ranges?

A: The BR66 operates from -65°C to 125°C, while the PB66-BP operates from -55°C to 150°C. The PB66-BP provides extended high-temperature capability. Selection depends on whether your application requires the lower temperature limit of -65°C. For most standard industrial applications operating within -55°C to 125°C, either component is suitable.

Q: Are there compliance differences between BR66 and PB66-BP?

A: The BR66 is RoHS Compliant. The PB66-BP is ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes. The PB66-BP provides additional regulatory documentation for applications requiring REACH compliance verification.

Q: Does the package designation difference (BR-6 versus PB-6) affect compatibility?

A: No. Both designations refer to the same 4-Square through-hole package form factor. The different naming conventions reflect manufacturer-specific package nomenclature but represent physically and electrically identical package configurations.

Q: What is the moisture sensitivity level for both components?

A: Both the BR66 and PB66-BP carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.
