Key Parameters

Substitute Part Grouping Explanation

Substitution of the VBO20-16NO2 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Peak reverse voltage must equal 1.6 kV
• Package / Case: Must be 4-Square, FO-A format
• Mounting Type: QC Terminal interface required
• Diode Type: Single-phase bridge rectifier topology
• Technology: Standard bridge rectifier technology
• Compliance: ROHS3 and REACH status maintained

The VBO25-16NO2 qualifies as a direct substitute based on matching all mandatory electrical and mechanical parameters. Current-carrying capacity differences (38 A vs. 31 A) represent an uprating that maintains full backward compatibility within the same voltage and package class.

Engineering Selection Recommendations

The VBO25-16NO2 is the qualified substitute for the obsolete VBO20-16NO2. Selection is based on the following engineering criteria:

• Electrical Equivalence: Both parts maintain identical peak reverse voltage (1.6 kV) and reverse leakage characteristics (300 µA @ 1600 V), ensuring circuit-level compatibility.
• Mechanical Compatibility: Identical 4-Square FO-A package and QC terminal mounting enable direct board-level replacement without layout modification.
• Product Status: The VBO25-16NO2 is active and maintains full ROHS3 and REACH compliance, providing long-term supply chain stability.
• Performance Enhancement: The VBO25-16NO2 offers improved forward voltage characteristics (1.36 V vs. 1.8 V @ 55 A), resulting in reduced thermal dissipation in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the VBO25-16NO2 directly replace the VBO20-16NO2 in existing designs?

A: Yes. Both parts share identical voltage ratings (1.6 kV), package format (4-Square, FO-A), and mounting interface (QC Terminal). The VBO25-16NO2 is rated for higher current (38 A vs. 31 A), making it suitable for all applications designed for the VBO20-16NO2.

Q: What is the difference in current rating between these parts?

A: The VBO20-16NO2 is rated for 31 A average rectified current, while the VBO25-16NO2 is rated for 38 A. This represents an uprating that maintains full backward compatibility.

Q: Are there any thermal or performance differences?

A: The VBO25-16NO2 exhibits lower forward voltage (1.36 V vs. 1.8 V @ 55 A), resulting in reduced power dissipation and improved thermal performance compared to the VBO20-16NO2.

Q: Does the VBO25-16NO2 require any circuit modifications?

A: No circuit modifications are required. The substitute maintains identical electrical specifications for voltage and leakage characteristics, and uses the same QC terminal interface.

Q: What is the compliance status of the substitute part?

A: The VBO25-16NO2 is ROHS3 compliant and REACH unaffected, matching the compliance profile of the original part.

Q: Why is the VBO20-16NO2 listed as obsolete?

A: The VBO20-16NO2 has been discontinued by IXYS. The VBO25-16NO2 serves as the active replacement within the same product family, offering improved specifications and ongoing manufacturer support.
