Substitute Part Grouping Explanation

Substitution of the KBP307G C2G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 1 kV
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 3 A
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBP

The KBP310G manufactured by Diotec Semiconductor satisfies all mandatory electrical and mechanical parameters. This substitute maintains identical peak reverse voltage, average rectified current, and forward voltage specifications. The through-hole KBP package configuration ensures mechanical and electrical compatibility with existing PCB layouts and circuit designs. The substitute component operates within the required temperature range and provides active product status with established supply availability.

Engineering Selection Recommendations

The KBP310G represents a direct electrical and mechanical equivalent to the obsolete KBP307G C2G. Selection of the KBP310G is appropriate for applications requiring replacement of end-of-life inventory or new designs requiring single-phase bridge rectification at 1 kV and 3 A specifications.

The KBP310G maintains all critical electrical parameters: peak reverse voltage of 1 kV, average rectified current of 3 A, and forward voltage of 1.1 V at 3 A. The through-hole KBP package configuration ensures direct PCB compatibility without layout modification. The substitute component exhibits superior reverse leakage characteristics (5 µA versus 10 µA), providing enhanced performance in this parameter.

The operating temperature range of the KBP310G extends to -50°C minimum, compared to -55°C for the original part. Applications requiring operation below -50°C require evaluation against specific system requirements. The KBP310G is actively manufactured by Diotec Semiconductor, ensuring long-term supply availability and established distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the KBP310G be used as a direct replacement for the KBP307G C2G in existing designs?

A: Yes. The KBP310G meets all mandatory electrical specifications: 1 kV peak reverse voltage, 3 A average rectified current, 1.1 V forward voltage at 3 A, and identical 4-SIP KBP package configuration. No circuit modifications are required for substitution.

Q: What is the significance of the lower reverse leakage current in the KBP310G?

A: The KBP310G exhibits 5 µA reverse leakage at 1000 V compared to 10 µA for the KBP307G C2G. Lower reverse leakage represents improved performance and does not create compatibility issues in applications designed for the original specification.

Q: Are there temperature range differences between these components?

A: The KBP310G operates from -50°C to 150°C, while the KBP307G C2G operates from -55°C to 150°C. The substitute component has a 5°C higher minimum operating temperature. Applications requiring operation below -50°C must be evaluated against specific system thermal requirements.

Q: Is the KBP package configuration identical between both components?

A: Yes. Both components use the 4-SIP, KBP through-hole package. Pin configuration, lead spacing, and PCB footprint are identical, enabling direct mechanical substitution without layout changes.

Q: Why is the KBP307G C2G classified as obsolete?

A: The KBP307G C2G is no longer manufactured by Taiwan Semiconductor Corporation. The KBP310G from Diotec Semiconductor provides equivalent functionality with active production status and established supply availability.

Q: What compliance certifications apply to the KBP310G?

A: The KBP310G is RoHS3 compliant. REACH status is listed as vendor undefined. Compliance requirements for specific applications should be verified against end-use regulatory requirements.
