PB36-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The PB36-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 600 V peak reverse voltage and 3 A average rectified current. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The through-hole PB-3 package configuration requires compatible alternatives with matching mechanical and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB36-BP are identified based on electrical and mechanical parameter equivalence. The primary substitution criteria are:

• Voltage - Peak Reverse (Max): 600 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: Compatible 4-Square configuration

The BR36 from GeneSiC Semiconductor meets these substitution criteria with matching voltage and current ratings, identical diode type and technology, and compatible through-hole mounting in a 4-Square package variant (BR-3).

Parameter Comparison

Engineering Selection Recommendations

The BR36 from GeneSiC Semiconductor is a direct substitute for the obsolete PB36-BP. Both components share identical voltage and current ratings, diode type, technology classification, and through-hole mounting configuration. The BR36 offers an extended lower operating temperature limit (-65°C versus -55°C) and improved forward voltage characteristics (1 V versus 1.2 V at 1.5 A), providing enhanced performance margins.

The BR36 maintains active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The 4-Square package variants (PB-3 and BR-3) are mechanically compatible for through-hole PCB applications. Inventory availability of the BR36 (18,800 pieces) supports immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the BR36 be used as a direct replacement for the PB36-BP in existing designs?

A: Yes. The BR36 meets all electrical specifications (600 V, 3 A, single-phase standard rectifier) and mounting requirements (through-hole, 4-Square package). The mechanical compatibility of the PB-3 and BR-3 package variants supports direct PCB substitution.

Q: What are the differences between the PB36-BP and BR36?

A: The primary differences are manufacturer (Micro Commercial Co versus GeneSiC Semiconductor), product status (obsolete versus active), and forward voltage characteristics (1.2 V versus 1 V at 1.5 A). The BR36 provides a wider operating temperature range (-65°C to 125°C versus -55°C to 125°C).

Q: Are there package compatibility concerns when substituting the BR36 for the PB36-BP?

A: Both components use 4-Square through-hole packages (PB-3 and BR-3 variants). Mechanical pin configuration and PCB footprint compatibility should be verified against the specific package datasheets to ensure proper board-level integration.

Q: Does the BR36 meet the same compliance requirements as the PB36-BP?

A: The BR36 is RoHS Compliant and carries Moisture Sensitivity Level 1 (Unlimited). The PB36-BP is ROHS3 Compliant. Both components share the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the availability status of these components?

A: The PB36-BP is obsolete with 770 pieces in stock. The BR36 is an active product with 18,800 pieces available, providing reliable long-term procurement options.
