VBO20-12NO2 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The VBO20-12NO2 is a single-phase bridge rectifier manufactured by IXYS, rated for 1.2 kV peak reverse voltage with 31 A average rectified current. This component features a QC Terminal mounting type in FO-A package configuration and operates across -40°C to 150°C junction temperature range.

The VBO20-12NO2 is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure supply chain availability for applications requiring single-phase bridge rectification at this voltage and current specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VBO20-12NO2 is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): Must equal or exceed 1.2 kV
• Diode Type: Must be Single Phase
• Mounting Type: Must be QC Terminal
• Package / Case: Must be 4-Square, FO-A
• Operating Temperature Range: Must support -40°C ~ 150°C (TJ)
• Technology: Must be Standard

The VBO25-12NO2 meets all substitution criteria. While the average rectified current rating increases from 31 A to 38 A, this represents an upward-compatible specification change. The forward voltage characteristic improves (1.36 V vs. 1.8 V @ 55 A), and all other electrical and mechanical parameters remain equivalent or superior.

Parameter Comparison

Engineering Selection Recommendations

The VBO25-12NO2 is the direct substitute for the VBO20-12NO2. Both components maintain identical voltage ratings, temperature operating ranges, and package configurations. The VBO25-12NO2 carries Active product status, ensuring ongoing availability and supply chain support compared to the Obsolete status of the original part.

Both components are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The VBO25-12NO2 provides improved electrical performance with lower forward voltage drop (1.36 V vs. 1.8 V @ 55 A) while maintaining the same reverse leakage characteristics.

Frequently Asked Questions (FAQ)

Q: Can the VBO25-12NO2 directly replace the VBO20-12NO2 in existing designs?

A: Yes. The VBO25-12NO2 maintains identical voltage ratings (1.2 kV peak reverse), operating temperature range (-40°C ~ 150°C), mounting type (QC Terminal), and package configuration (4-Square, FO-A). The increased current rating (38 A vs. 31 A) represents an upward-compatible specification.

Q: What is the primary difference between these two parts?

A: The VBO25-12NO2 has a higher average rectified current rating (38 A compared to 31 A) and lower forward voltage drop (1.36 V vs. 1.8 V @ 55 A). All other electrical and mechanical parameters are equivalent.

Q: Are there any package or mounting differences?

A: No. Both components use identical QC Terminal mounting and 4-Square FO-A package configuration. Physical and electrical interface compatibility is maintained.

Q: What is the significance of the product status difference?

A: The VBO20-12NO2 is classified as Obsolete, while the VBO25-12NO2 is Active. Active status indicates ongoing manufacturing and supply availability, making the VBO25-12NO2 the recommended choice for new designs and ongoing production.

Q: Do both parts meet current compliance standards?

A: Yes. Both the VBO20-12NO2 and VBO25-12NO2 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.
