KBPC15005T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC15005T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, designed for standard rectification applications requiring 50 V peak reverse voltage and 15 A average rectified current. The device features QC terminal mounting and operates across the industrial temperature range of -55°C to 150°C. This part maintains Active product status and is RoHS Compliant.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining compatible mechanical packaging and thermal characteristics. The KBPC15005T may require substitution due to inventory availability, supply chain constraints, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KBPC15005T is determined by the following criteria:

Voltage Compatibility: Peak reverse voltage must equal or exceed 50 V to maintain dielectric safety margins in the application circuit.

Current Rating: The average rectified current (Io) establishes the thermal and conduction capability requirement. Substitutes must support the application's current demand.

Forward Voltage Characteristics: Forward voltage drop (Vf) at specified current levels affects power dissipation and thermal management. Equivalent or lower Vf values are acceptable.

Reverse Leakage Current: Leakage characteristics at rated voltage determine standby power consumption and circuit performance in high-impedance applications.

Thermal Operating Range: The -55°C to 150°C junction temperature range defines the environmental suitability. Substitutes must support this range.

Mechanical Packaging: QC terminal mounting and 4-Square KBPC package form factor ensure physical and electrical compatibility with existing PCB layouts and thermal management solutions.

Diode Type and Technology: Single-phase standard bridge rectifier topology must be maintained for functional equivalence.

Engineering Selection Recommendations

Primary Part (KBPC15005T): Recommended for applications requiring the full 15 A average rectified current rating. GeneSiC Semiconductor maintains Active product status with RoHS Compliance and MSL Level 1 (Unlimited moisture sensitivity). This part is suitable for standard industrial rectification circuits operating within the specified voltage and temperature parameters.

Substitute Part (KBPC10005-G): The KBPC10005-G from Comchip Technology is electrically compatible for applications with maximum current requirements of 10 A or less. This substitute maintains identical peak reverse voltage (50 V), operating temperature range (-55°C to 150°C), and mounting configuration (QC Terminal, 4-Square KBPC package). Both parts are RoHS compliant and MSL Level 1. The substitute exhibits higher reverse leakage current (10 µA versus 5 µA at 50 V), which may affect standby power consumption in sensitive applications. Forward voltage characteristics remain equivalent at their respective current ratings.

Compliance Status: Both parts are RoHS compliant and classified under ECCN EAR99 with HTSUS code 8541.10.0080, ensuring regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can KBPC10005-G replace KBPC15005T in all applications?

A: The KBPC10005-G is suitable only for applications where the average rectified current does not exceed 10 A. If your circuit requires the full 15 A rating of the KBPC15005T, the substitute is not appropriate. Verify your application's actual current demand before substitution.

Q: What is the significance of the different reverse leakage current values?

A: The KBPC15005T specifies 5 µA reverse leakage at 50 V, while the KBPC10005-G specifies 10 µA. Higher leakage current increases standby power consumption and may affect circuit performance in high-impedance or precision measurement applications. For standard rectification circuits, this difference is typically negligible.

Q: Are the package dimensions identical between these parts?

A: Both parts use QC terminal mounting and 4-Square KBPC package form factors, ensuring mechanical compatibility with existing PCB layouts. The KBPC15005T uses the KBPC-T variant designation, while the KBPC10005-G uses the standard KBPC designation. Physical dimensions and terminal spacing are compatible for direct substitution.

Q: Do both parts meet the same compliance requirements?

A: Both the KBPC15005T and KBPC10005-G are RoHS compliant, MSL Level 1 (Unlimited), and classified as EAR99 for export control purposes. The KBPC10005-G carries ROHS3 Compliant status and REACH Unaffected designation, providing additional regulatory documentation.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical junction temperature range of -55°C to 150°C, ensuring thermal compatibility in industrial and extended-temperature applications.

Q: How do forward voltage characteristics compare?

A: Both parts specify 1.1 V maximum forward voltage drop. The KBPC15005T is rated at 7.5 A, while the KBPC10005-G is rated at 5 A. At their respective current levels, forward voltage performance is equivalent, resulting in similar power dissipation characteristics within their rated current ranges.
