Key Parameters

Substitute Part Grouping Explanation

Substitution of the VBO13-16AO2 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Peak Reverse (Max): 1.6 kV
• Diode Type: Single Phase
• Technology: Avalanche
• Mounting Type: QC Terminal
• Package / Case: 4-Square, FO-A

Allowable Variation Parameters:

• Current - Average Rectified (Io): May be equal to or greater than 18 A
• Voltage - Forward (Vf): May be lower than or equal to 1.8 V @ 55 A
• Current - Reverse Leakage @ Vr: Must not exceed 300 µA @ 1600 V
• Operating Temperature Range: Must encompass or match -40°C ~ 150°C (TJ)

The VBO25-16AO2 qualifies as a direct substitute based on matching all critical parameters while providing enhanced current capacity (38 A versus 18 A) and improved forward voltage characteristics (1.36 V versus 1.8 V @ 55 A).

Both parts satisfy ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity classifications. The VBO25-16AO2 provides superior electrical performance through increased current capacity and reduced forward voltage drop, making it suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the VBO25-16AO2 directly replace the VBO13-16AO2 in existing applications?

A: Yes. The VBO25-16AO2 maintains identical voltage ratings (1.6 kV peak reverse), diode type (single phase), technology (avalanche), mounting type (QC Terminal), and package configuration (4-Square, FO-A). No circuit redesign is required.

Q: What are the key differences between these two parts?

A: The VBO25-16AO2 provides higher average rectified current capacity (38 A versus 18 A) and lower forward voltage drop (1.36 V versus 1.8 V @ 55 A). The VBO25-16AO2 is in active production, while the VBO13-16AO2 is obsolete.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited).

Q: Does the higher current rating of the VBO25-16AO2 affect thermal performance?

A: Thermal performance is determined by the specific application circuit and thermal management design. The lower forward voltage of the VBO25-16AO2 may result in reduced power dissipation compared to the VBO13-16AO2 under equivalent operating conditions.

Q: Are both parts available in the same package configuration?

A: Yes. Both the VBO13-16AO2 and VBO25-16AO2 use the 4-Square, FO-A package with QC Terminal mounting type, ensuring mechanical and electrical interface compatibility.
