KBPC50005T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC50005T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 50 V peak reverse voltage and 50 A average rectified current. This component is classified as Active and RoHS Compliant, designed for applications requiring full-wave rectification in standard industrial and commercial power conversion circuits. The QC Terminal mounting type and 4-Square KBPC package provide standard integration into PCB and module assemblies. Substitute parts are identified based on matching voltage ratings, package type, and thermal operating range while accommodating variations in current capacity and forward voltage characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KBPC50005T are identified based on the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Voltage - Peak Reverse (Max): 50 V
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: QC Terminal
• Package / Case: 4-Square, KBPC family
• Operating Temperature Range: -55°C to 150°C (TJ)

Variable Parameters (Allowed to Differ):

• Current - Average Rectified (Io): Lower current ratings are acceptable for applications with reduced current demands
• Voltage - Forward (Vf) (Max): Minor variations within the same technology class
• Current - Reverse Leakage @ Vr: Acceptable within standard specifications
• Manufacturer and specific part number designation
• RoHS compliance variant (RoHS Compliant vs. ROHS3 Compliant)

The KBPC10005-G substitute part maintains identical voltage and temperature specifications while reducing the current capacity from 50 A to 10 A. This substitution is valid for circuits designed to operate at or below 10 A average rectified current.

Parameter Comparison

Engineering Selection Recommendations

KBPC50005T (GeneSiC Semiconductor) is the primary component specification for applications requiring 50 A average rectified current at 50 V peak reverse voltage. This part is Active status and RoHS Compliant, suitable for new designs and production environments with established supply chains.

KBPC10005-G (Comchip Technology) serves as a substitute for applications with maximum current requirements of 10 A or less. This part is also Active status and ROHS3 Compliant, providing an alternative source with different manufacturer compliance documentation. The substitute maintains voltage and temperature specifications but operates at reduced current capacity and exhibits higher reverse leakage current (10 µA vs. 5 µA).

Selection between these parts depends on circuit current requirements:

• Use KBPC50005T for designs requiring 10 A to 50 A average rectified current
• Use KBPC10005-G for designs requiring 10 A or less average rectified current

Both parts share identical QC Terminal mounting, 4-Square KBPC package family, and -55°C to 150°C operating temperature range, ensuring mechanical and thermal compatibility within their respective current ratings.

Frequently Asked Questions (FAQ)

Q: Can KBPC10005-G replace KBPC50005T in all applications?

A: No. The KBPC10005-G is rated for 10 A average rectified current, while the KBPC50005T is rated for 50 A. The substitute part is only suitable for circuits designed to operate at or below 10 A. Using a lower-rated component in a higher-current application will result in component failure or thermal damage.

Q: Are the packages physically identical?

A: Both parts use the 4-Square KBPC package family with QC Terminal mounting type. The physical footprint and terminal configuration are compatible, allowing direct PCB substitution within current rating constraints.

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

A: The KBPC50005T has a maximum reverse leakage of 5 µA at 50 V, while the KBPC10005-G has a maximum of 10 µA at 50 V. This difference is within standard specifications for single-phase bridge rectifiers and does not affect substitution validity for applications within the 10 A current range.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the KBPC50005T and KBPC10005-G operate from -55°C to 150°C junction temperature (TJ), ensuring thermal compatibility in equivalent operating environments.

Q: What is the difference in RoHS compliance status?

A: The KBPC50005T is RoHS Compliant, while the KBPC10005-G is ROHS3 Compliant. Both designations indicate compliance with lead-free and hazardous substance restrictions. ROHS3 represents a more recent compliance standard. Both parts are acceptable for RoHS-regulated applications.

Q: Can KBPC50005T be used as a substitute for KBPC10005-G?

A: Yes. The KBPC50005T can replace the KBPC10005-G in any application, as it provides higher current capacity (50 A vs. 10 A) and lower reverse leakage (5 µA vs. 10 µA). This represents an upgrade path for designs requiring increased current handling or improved leakage characteristics.

Q: Are there inventory considerations for these parts?

A: The KBPC50005T has 885 pieces in stock, while the KBPC10005-G has 1512 pieces in stock. Availability may influence component selection for time-sensitive production requirements.
