PBPC606 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The PBPC606 is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 800 V peak reverse voltage and 4 A average rectified current. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The PBPC606 features a through-hole PBPC-6 package and operates across a temperature range of -65°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PBPC606 is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): Must equal or exceed 800 V
• Diode Type: Must be Single Phase
• Mounting Type: Must be Through Hole
• Package / Case: Must be compatible 4-Square configuration
• Current - Average Rectified (Io): Must meet or exceed 4 A minimum requirement
• Operating Temperature Range: Must encompass or exceed the specified range
• Technology: Must be Standard bridge rectifier technology

Both substitute parts meet these criteria while offering enhanced current ratings and maintained voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

Both BR68 and PB68-BP are active production alternatives to the obsolete PBPC606. Selection between these substitutes should be based on the following factors:

BR68 (GeneSiC Semiconductor): This substitute offers a lower forward voltage drop (1 V @ 3 A compared to 1.1 V @ 3 A), resulting in reduced power dissipation. It maintains the same operating temperature range as the original part and carries RoHS compliance certification. The 6 A current rating provides a 50% margin above the PBPC606 requirement.

PB68-BP (Micro Commercial Co): This substitute maintains identical forward voltage characteristics to the PBPC606 (1.1 V @ 3 A) and extends the operating temperature range to -55°C ~ 150°C, offering broader thermal performance. It carries ROHS3 compliance and is REACH unaffected. The 6 A current rating similarly provides design margin.

Both substitutes are electrically and mechanically compatible with the PBPC606 in through-hole applications requiring 800 V, 4 A single-phase bridge rectification.

Frequently Asked Questions (FAQ)

Q: Can BR68 and PB68-BP be used interchangeably with PBPC606?

A: Both BR68 and PB68-BP meet the electrical and mechanical requirements for PBPC606 substitution. They share identical peak reverse voltage (800 V), reverse leakage current (10 µA @ 800 V), and through-hole mounting configuration. Both exceed the 4 A current requirement at 6 A rated capacity. Package compatibility exists within the 4-Square family, though physical pin layouts should be verified for PCB footprint alignment.

Q: What is the significance of the current rating difference between PBPC606 (4 A) and the substitutes (6 A)?

A: The substitute parts are rated for higher average rectified current (6 A versus 4 A). This provides additional thermal and electrical margin in the application. The PBPC606 can be replaced by either substitute in circuits designed for 4 A operation, as the substitutes are rated for higher current capacity.

Q: How do forward voltage drops affect circuit performance?

A: BR68 exhibits a lower forward voltage drop (1 V @ 3 A) compared to PBPC606 and PB68-BP (both 1.1 V @ 3 A). In high-current or thermally sensitive applications, the BR68 may result in reduced power dissipation and lower junction temperatures. For circuits where forward voltage is a critical parameter, this difference should be evaluated against application requirements.

Q: Are there temperature range considerations for substitution?

A: PBPC606 operates from -65°C to 125°C. BR68 maintains this identical range. PB68-BP extends the upper temperature limit to 150°C, providing enhanced thermal performance for high-temperature environments. For applications operating within the -65°C to 125°C window, both substitutes are suitable. For applications exceeding 125°C, PB68-BP is the appropriate selection.

Q: What compliance certifications apply to these parts?

A: PBPC606 is ROHS3 compliant and REACH affected. BR68 is RoHS compliant. PB68-BP is ROHS3 compliant and REACH unaffected. All three parts carry EAR99 ECCN classification and 8541.10.0080 HTSUS code. Compliance requirements for your application should determine the appropriate substitute selection.

Q: Why is PBPC606 classified as obsolete?

A: Obsolescence indicates that Diodes Incorporated has discontinued production of this part. Active alternatives BR68 and PB68-BP provide equivalent functionality with current manufacturing support and availability.
