BR810 Bridge Rectifier Single Phase 1 kV 8A Equivalent & Substitute Parts

Part Overview

The BR810 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 1 kV peak reverse voltage and 8 A average rectified current. This component is designed for Through Hole mounting in the BR-8 package configuration and operates across a temperature range of -65°C to 125°C. The part maintains Active product status and is RoHS Compliant, making it suitable for modern electronic applications requiring AC-to-DC conversion in industrial and consumer equipment.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining mechanical compatibility and regulatory compliance. Alternative models may be required due to inventory availability, packaging preferences, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BR810 is determined by strict alignment with the following critical parameters:

Electrical Compatibility Requirements:

• Voltage - Peak Reverse (Max): Must equal or exceed 1 kV
• Current - Average Rectified (Io): Must equal or exceed 8 A
• Voltage - Forward (Vf) (Max): Must not exceed 1.1 V at the specified forward current
• Current - Reverse Leakage: Must not exceed 10 µA at 1000 V

Mechanical & Environmental Requirements:

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package Configuration: 4-Square format (BR-8 or equivalent MP-8)
• Operating Temperature Range: Must encompass or exceed -65°C to 125°C

Regulatory & Compliance Requirements:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The substitute part MP1010G-G from Comchip Technology meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

BR810 Selection Criteria: The BR810 is the primary component choice when GeneSiC Semiconductor sourcing is specified or when the lower operating temperature minimum of -65°C is required for extreme cold-environment applications. This part maintains Active product status with RoHS Compliance and is available in Bulk packaging with 993 pieces in current inventory.

MP1010G-G Selection Criteria: The MP1010G-G from Comchip Technology serves as a direct electrical substitute with enhanced current capacity (10 A versus 8 A) and extended upper operating temperature rating (150°C versus 125°C). This part is ROHS3 Compliant and available in Tray packaging with 1850 pieces in current inventory. The MP1010G-G is suitable for applications where higher current margin or elevated temperature operation provides system design benefits.

Compatibility Determination: Both parts share identical voltage ratings (1 kV peak reverse), matching reverse leakage characteristics (10 µA @ 1000 V), and equivalent forward voltage performance (1.1 V maximum). The 4-Square package format ensures mechanical interchangeability in Through Hole PCB applications. Selection between these parts depends on specific application requirements regarding current headroom, temperature extremes, and supply chain availability rather than electrical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can MP1010G-G replace BR810 in all applications?

A: MP1010G-G is electrically and mechanically compatible with BR810 for applications operating within the BR810 temperature range (-65°C to 125°C). The substitute part's higher current rating (10 A) and extended upper temperature limit (150°C) do not create incompatibility. PCB layout and Through Hole mounting procedures remain identical.

Q: What is the difference between BR-8 and MP-8 packages?

A: Both BR-8 and MP-8 are 4-Square Through Hole package configurations with identical mechanical footprints and pin assignments. The package designation reflects manufacturer nomenclature only; physical compatibility is confirmed.

Q: Are there temperature limitations when substituting?

A: The BR810 operates from -65°C to 125°C. The MP1010G-G operates from -55°C to 150°C. For applications requiring operation below -55°C, BR810 is the required choice. For applications above 125°C, MP1010G-G provides extended capability.

Q: Do both parts meet current RoHS requirements?

A: Yes. BR810 is RoHS Compliant. MP1010G-G is ROHS3 Compliant. Both certifications satisfy modern regulatory requirements for lead-free and restricted substance compliance.

Q: What is the current rating difference, and does it affect circuit design?

A: BR810 is rated for 8 A average rectified current; MP1010G-G is rated for 10 A. In applications designed for 8 A operation, MP1010G-G provides 25% additional current margin without requiring circuit modification. This does not create incompatibility; it represents improved thermal headroom.

Q: Are packaging formats (Bulk vs. Tray) relevant to electrical performance?

A: Packaging format (Bulk for BR810, Tray for MP1010G-G) affects only handling, storage, and procurement logistics. Electrical and mechanical performance are identical regardless of packaging configuration.
