BR61 Bridge Rectifier Single Phase 100V 6A Equivalent & Substitute Parts

Part Overview

The BR61 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 100 V peak reverse voltage and 6 A average rectified current. This component is classified as Active product status and is RoHS Compliant. Bridge rectifiers in this specification range are used in AC-to-DC conversion applications requiring through-hole mounting in 4-Square BR-6 package configuration.

Substitute parts become necessary when the primary BR61 is unavailable, when design requirements permit alternative manufacturers, or when inventory constraints require sourcing from alternative suppliers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the BR61 with the PB61-BP is determined by equivalence in the following critical parameters:

Electrical Equivalence Criteria:

Voltage - Peak Reverse (Max): 100 V (identical)
Current - Average Rectified (Io): 6 A (identical)
Current - Reverse Leakage @ Vr: 10 µA @ 100 V (identical)
Diode Type: Single Phase (identical)
Technology: Standard (identical)

Mechanical Equivalence Criteria:

Mounting Type: Through Hole (identical)
Package Configuration: 4-Square form factor (BR-6 and PB-6 are equivalent 4-Square packages)

Acceptable Parameter Variations:

Voltage - Forward (Vf) (Max) @ If: BR61 = 1 V @ 3 A; PB61-BP = 1.1 V @ 3 A (within acceptable tolerance for bridge rectifier applications)
Operating Temperature Range: BR61 = -65°C to 125°C; PB61-BP = -55°C to 150°C (both ranges support standard industrial applications)

The PB61-BP qualifies as a direct substitute based on matching electrical ratings and through-hole 4-Square package compatibility.

Engineering Selection Recommendations

BR61 Selection Criteria:

Primary choice for new designs requiring GeneSiC Semiconductor sourcing
Active product status ensures long-term availability and supply chain stability
RoHS Compliant certification meets environmental regulatory requirements
Operating temperature range of -65°C to 125°C supports extended temperature applications
Forward voltage specification of 1 V @ 3 A provides optimal efficiency in standard rectification circuits

PB61-BP Selection Criteria:

Suitable for applications where Micro Commercial Co sourcing is preferred or required
Product status is Not For New Designs; use restricted to replacement, repair, or legacy system applications
ROHS3 Compliant certification meets current environmental standards
Operating temperature range of -55°C to 150°C accommodates high-temperature environments
Forward voltage specification of 1.1 V @ 3 A is acceptable in applications with thermal margin
Higher inventory availability (2184 Pcs) supports immediate procurement needs

Compliance Considerations: Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, ensuring equivalent export and tariff treatment. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can PB61-BP replace BR61 in existing designs? A: Yes. The PB61-BP meets all critical electrical parameters (100 V peak reverse voltage, 6 A average rectified current, 10 µA reverse leakage) and uses equivalent through-hole 4-Square packaging. The 0.1 V forward voltage difference (1.1 V vs 1 V @ 3 A) is within acceptable tolerance for standard bridge rectifier applications.

Q: What is the difference between BR-6 and PB-6 packages? A: Both BR-6 and PB-6 are 4-Square through-hole package configurations with identical mechanical footprints and pin assignments. They are mechanically and electrically interchangeable for PCB mounting purposes.

Q: Why is PB61-BP marked "Not For New Designs"? A: This product status indicates that Micro Commercial Co has discontinued active development and long-term support for this part. It remains available for replacement and repair applications but should not be selected for new product development. BR61 is the recommended choice for new designs.

Q: Are there temperature range limitations when substituting? A: BR61 operates from -65°C to 125°C, while PB61-BP operates from -55°C to 150°C. If your application requires operation below -55°C, BR61 is required. If operation above 125°C is needed, PB61-BP is required. For standard industrial temperature ranges (-40°C to 85°C), both parts are suitable.

Q: Do both parts meet RoHS requirements? A: Yes. BR61 is RoHS Compliant, and PB61-BP is ROHS3 Compliant. Both meet current environmental and regulatory standards for electronic component manufacturing and use.

Q: What is the pin configuration for through-hole mounting? A: Both BR61 and PB61-BP use standard 4-Square bridge rectifier pin configuration with AC input terminals, positive output terminal, and negative output terminal. Mechanical footprints are identical.
