Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP156G C2 is determined by matching the following critical electrical and mechanical parameters:

• Voltage Rating: Peak reverse voltage must equal 800 V
• Current Rating: Average rectified current must equal 1.5 A
• Diode Configuration: Single-phase bridge rectifier topology
• Technology Class: Standard rectifier technology
• Package Type: 4-SIP KBP form factor with through-hole mounting
• Compliance: ROHS3 compliance and EAR99 classification

The KBP08G from Diodes Incorporated satisfies all substitution criteria, maintaining electrical equivalence across voltage, current, and thermal specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The KBP08G is a direct functional equivalent for the obsolete KBP156G C2. Both components share identical electrical specifications for voltage rating (800 V), current rating (1.5 A), forward voltage drop (1.1 V @ 1.5 A), and package configuration (4-SIP KBP through-hole).

The KBP08G offers the following advantages:

• Active Product Status: Currently manufactured and supported by Diodes Incorporated, ensuring long-term availability and supply chain stability
• Improved Leakage Performance: Reverse leakage current of 5 µA at 800 V compared to 10 µA in the original part, indicating superior device quality
• Extended Low-Temperature Rating: Operating range extends to -65°C versus -55°C, providing broader thermal envelope coverage
• Regulatory Compliance: Maintains ROHS3 compliance, REACH unaffected status, and EAR99 classification identical to the original part

Direct pin-for-pin and functional substitution is supported without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the KBP08G be used as a direct replacement for the KBP156G C2 in existing designs?

A: Yes. The KBP08G is electrically and mechanically equivalent. Both components feature identical voltage ratings (800 V), current ratings (1.5 A), forward voltage characteristics (1.1 V @ 1.5 A), and 4-SIP KBP package configuration. No circuit redesign is required.

Q: What is the significance of the lower reverse leakage current in the KBP08G?

A: The KBP08G exhibits 5 µA reverse leakage at 800 V compared to 10 µA in the KBP156G C2. Lower leakage current indicates improved device quality and reduced power dissipation during reverse bias operation, which can enhance overall circuit efficiency and thermal performance.

Q: Are there any temperature range differences between these parts?

A: The KBP08G operates from -65°C to 150°C, while the KBP156G C2 operates from -55°C to 150°C. The KBP08G provides an extended low-temperature operating range of 10°C, suitable for applications requiring operation in colder environments.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the KBP156G C2 and KBP08G are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental compliance requirements are identical.

Q: Is the packaging identical between the two parts?

A: Yes. Both components use the 4-SIP KBP through-hole package configuration. PCB footprints and mounting procedures are identical, enabling direct substitution without layout modifications.

Q: Why is the KBP156G C2 listed as obsolete?

A: Obsolete status indicates that Taiwan Semiconductor Corporation has discontinued manufacturing this component. The KBP08G from Diodes Incorporated remains in active production, providing a viable alternative for new designs and replacement applications.
