BR36 Bridge Rectifier Single Phase 600V 3A Equivalent & Substitute Parts

Part Overview

The BR36 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 600V peak reverse voltage and 3A average rectified current. This component is designed for through-hole mounting applications requiring standard rectification technology. The BR36 maintains active product status with 18,800 units in current inventory.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter ranges for this diode category, accounting for differences in current ratings, forward voltage characteristics, and operating temperature specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BR36 is determined by the following criteria:

Voltage Rating Compatibility: The substitute part must maintain the 600V peak reverse voltage specification to ensure safe operation in the target circuit.

Current Rating Consideration: The BR36 is rated for 3A average rectified current. Substitute parts with equal or higher current ratings (such as 6A) are electrically compatible, as they can safely handle the specified load without exceeding thermal or electrical limits.

Forward Voltage Characteristics: Forward voltage drop must be within acceptable ranges for the application. The BR36 specifies 1V maximum at 1.5A; substitute parts with slightly higher forward voltage (1.1V at 3A) remain functionally equivalent for standard rectification circuits.

Reverse Leakage Current: The 10µA maximum reverse leakage at 600V is a standard specification for this diode category and is maintained across substitute parts.

Mounting and Package: Through-hole mounting with 4-square package configuration is required for mechanical compatibility.

Compliance and Status: Active product status and RoHS compliance are baseline requirements for substitute selection.

Parameter Comparison

Engineering Selection Recommendations

BR36 Selection: The BR36 is appropriate for applications requiring exactly 3A average rectified current at 600V with the specified forward voltage characteristics. This part maintains active product status with established supply availability.

PB66-BP Selection: The PB66-BP is suitable as a substitute when higher current capacity (6A) is acceptable or beneficial for the application. The higher current rating provides additional thermal margin without compromising voltage specifications. The PB66-BP extends the upper operating temperature limit to 150°C, offering enhanced thermal performance in high-temperature environments. Both parts maintain equivalent RoHS compliance and moisture sensitivity ratings.

Compliance Considerations: Both parts are RoHS compliant and classified under identical HTSUS and ECCN codes, ensuring regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can the PB66-BP directly replace the BR36 in all applications?

A: The PB66-BP is electrically compatible with the BR36 for circuits designed around the 3A specification. The higher 6A rating of the PB66-BP does not create incompatibility; it provides additional current capacity. Physical package dimensions (4-Square configuration) are compatible for through-hole mounting. Forward voltage differences (1.1V vs 1V) are within acceptable ranges for standard rectification circuits.

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

A: The BR36 operates from -65°C to 125°C, while the PB66-BP operates from -55°C to 150°C. The PB66-BP provides a wider upper temperature range, making it suitable for applications in elevated-temperature environments. The BR36 extends to lower temperatures (-65°C vs -55°C), making it preferable for cryogenic or extreme cold applications.

Q: Are the package designations BR-3 and PB-6 interchangeable?

A: Both use 4-Square through-hole package configuration and are mechanically compatible for PCB mounting. The different designations (BR-3 and PB-6) reflect manufacturer-specific package naming conventions but represent equivalent physical form factors.

Q: How do the forward voltage specifications affect circuit performance?

A: The BR36 specifies 1V maximum at 1.5A, while the PB66-BP specifies 1.1V maximum at 3A. The 0.1V difference is negligible in most rectification applications and does not affect circuit functionality. Power dissipation differences are minimal at the 3A operating point.

Q: What does RoHS3 compliance mean compared to RoHS compliance?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the standard. Both parts meet equivalent environmental and material restrictions for electronic components.
