BR310 Bridge Rectifier Single Phase 1 kV 3 A Equivalent & Substitute Parts

Part Overview

The BR310 is an active single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 1 kV peak reverse voltage and 3 A average rectified current. This component is designed for through-hole mounting in standard BR-3 package configuration and operates across the temperature range of -65°C to 125°C. The BR310 is RoHS compliant and classified as Unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining compatibility with the through-hole mounting footprint and operating environment requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BR310 is determined by the following critical parameters:

Voltage Rating Compatibility: Peak reverse voltage must equal or exceed 1 kV. The substitute part PB610-BP maintains the 1 kV rating, ensuring equivalent voltage stress capability.

Current Rating Consideration: The BR310 specifies 3 A average rectified current. The substitute PB610-BP is rated for 6 A, which exceeds the minimum requirement. Higher current ratings do not prevent substitution in applications where the actual load current does not exceed the BR310 specification.

Forward Voltage Characteristics: The BR310 forward voltage is 1 V maximum at 1.5 A. The substitute PB610-BP specifies 1.1 V at 3 A. Both values remain within acceptable rectifier performance ranges for standard applications.

Reverse Leakage Current: Both parts specify 10 µA at 1000 V, indicating equivalent leakage performance.

Mounting and Package: Both parts use through-hole mounting with 4-square package configuration (BR-3 and PB-6 respectively), ensuring mechanical compatibility with standard PCB layouts designed for single-phase bridge rectifiers.

Environmental and Compliance: Both parts maintain RoHS compliance and MSL 1 rating, suitable for standard industrial and commercial applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (BR310): The BR310 remains the specified component for applications designed to its exact electrical and thermal parameters. Active product status and full RoHS compliance support continued use in new designs and production environments.

Substitute Selection (PB610-BP): The PB610-BP is suitable for applications where the BR310 is unavailable. The substitute provides equivalent voltage performance and exceeds current requirements, making it functionally compatible for circuits designed around the BR310 specification. The wider operating temperature range (-55°C to 150°C versus -65°C to 125°C) accommodates extended thermal environments. ROHS3 compliance maintains regulatory alignment with current standards.

Inventory Consideration: BR310 inventory (8800 pcs) exceeds PB610-BP availability (2429 pcs), supporting preference for the primary part in high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can PB610-BP directly replace BR310 in existing circuit designs?

A: Yes. Both parts maintain 1 kV peak reverse voltage, equivalent reverse leakage current, and through-hole mounting compatibility. The PB610-BP higher current rating (6 A versus 3 A) does not prevent substitution in applications where actual load current remains within BR310 specification limits.

Q: What are the package differences between BR-3 and PB-6?

A: Both use 4-square through-hole package configuration. The designations (BR-3 and PB-6) reflect manufacturer-specific naming conventions but maintain compatible PCB footprints for standard single-phase bridge rectifier applications.

Q: How do forward voltage differences affect circuit performance?

A: BR310 specifies 1 V at 1.5 A; PB610-BP specifies 1.1 V at 3 A. The 0.1 V difference at higher current represents normal variation within rectifier technology. Both values are standard for silicon bridge rectifiers and do not significantly impact power supply regulation or efficiency in typical applications.

Q: Are there temperature range limitations when substituting?

A: The PB610-BP operates from -55°C to 150°C, compared to BR310 range of -65°C to 125°C. For applications requiring operation below -55°C or above 150°C, the BR310 remains necessary. For standard industrial temperature ranges (-40°C to 85°C), both parts are suitable.

Q: Do compliance certifications differ between the parts?

A: Both parts are RoHS compliant. BR310 carries RoHS standard compliance; PB610-BP carries ROHS3 compliance, representing current regulatory alignment. Both meet environmental and hazardous substance restrictions for commercial and industrial applications.

Q: What inventory factors should influence part selection?

A: BR310 inventory (8800 pcs) significantly exceeds PB610-BP (2429 pcs). For production planning, BR310 availability supports sustained supply for high-volume manufacturing. PB610-BP serves as a secondary source for limited-quantity requirements or supply chain contingency.
