KBPC1506T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC1506T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 600 V peak reverse voltage and 15 A average rectified current. This component operates across the temperature range of -55°C to 150°C and features QC terminal mounting with a 4-square KBPC-T package configuration. The part maintains active product status and RoHS compliance, making it suitable for industrial power conversion applications requiring standard bridge rectification.

Substitute parts are identified based on electrical parameter compatibility within the single-phase bridge rectifier category, allowing for component selection flexibility when the primary part is unavailable or when application requirements permit operation at different current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KBPC1506T are qualified based on the following criteria:

Mandatory Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 600 V
• Mounting Type: QC Terminal
• Operating Temperature Range: -55°C to 150°C (TJ)
• Package / Case: 4-Square configuration

Variable Parameters (Allows Substitution):

• Current - Average Rectified (Io): Substitute parts rated at 10 A, 25 A, 35 A, or 50 A are electrically compatible when application current requirements do not exceed the substitute part's rating
• Voltage - Forward (Vf) (Max) @ If: Maintained at 1.1 V across all substitute parts
• Current - Reverse Leakage @ Vr: Maintained at 10 µA @ 600 V across all substitute parts
• Manufacturer: GeneSiC Semiconductor (main part) or Comchip Technology (substitute parts)
• Packaging: Bulk or Tray configurations are interchangeable for component selection purposes

All substitute parts maintain active product status and compliance certifications (RoHS3 or RoHS Compliant), ensuring regulatory alignment with the original KBPC1506T.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Current Rating): No substitute part is rated identically at 15 A. The KBPC1506T operates at a unique current specification within the available substitute portfolio.

For Higher Current Capacity Applications: When application requirements permit operation at elevated current ratings, KBPC2506-G (25 A), KBPC3506-G (35 A), KBPC5006-G (50 A), or GBPC5006-G (50 A) provide increased current handling capacity while maintaining identical voltage specifications and thermal operating range.

For Lower Current Capacity Applications: KBPC1006-G (10 A) is suitable for applications requiring reduced current capacity, maintaining all other electrical and thermal parameters.

Compliance Considerations: All substitute parts maintain ROHS3 compliance or equivalent RoHS certification. The KBPC1506T is RoHS Compliant; substitute parts from Comchip Technology carry ROHS3 Compliant status with REACH Unaffected designation, ensuring regulatory alignment across supply chain requirements.

Packaging and Inventory: Substitute parts are available in both Bulk and Tray packaging configurations. Selection between packaging types depends on procurement volume and handling requirements rather than electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can KBPC1006-G replace KBPC1506T in all applications?

A: KBPC1006-G is electrically compatible with KBPC1506T when the application current requirement does not exceed 10 A. Both parts share identical voltage ratings (600 V peak reverse), forward voltage characteristics (1.1 V), reverse leakage (10 µA @ 600 V), and operating temperature range (-55°C to 150°C). Selection depends on actual circuit current demand.

Q: What is the difference between KBPC5006-G and GBPC5006-G?

A: Both parts are rated at 50 A, 600 V, with identical electrical characteristics. The primary difference is the package designation: KBPC5006-G uses the KBPC package, while GBPC5006-G uses the GBPC package. Both maintain 4-square terminal configuration and QC terminal mounting. Package selection depends on PCB layout and mechanical mounting requirements.

Q: Are all substitute parts suitable for the full -55°C to 150°C operating range?

A: Yes. All substitute parts listed maintain the identical operating temperature range of -55°C to 150°C (TJ), ensuring thermal compatibility across the full specification envelope.

Q: Does current rating affect forward voltage drop?

A: Forward voltage (Vf) remains at 1.1 V maximum across all parts. However, the test current (If) at which this specification is measured varies with part rating: KBPC1006-G at 5 A, KBPC1506T at 7.5 A, KBPC2506-G at 12.5 A, KBPC3506-G at 17.5 A, and KBPC5006-G/GBPC5006-G at 25 A. This reflects proportional scaling to each part's current rating.

Q: Can I use a higher-rated substitute in a circuit designed for KBPC1506T?

A: Yes, when the substitute part's current rating exceeds the application requirement. A 25 A, 35 A, or 50 A rated part operates safely in a 15 A circuit. The substitute part will not be stressed beyond its design limits. Verify that PCB thermal management and mechanical mounting accommodate the substitute package dimensions.

Q: What is the significance of MSL Level 1 (Unlimited)?

A: MSL Level 1 indicates unlimited shelf life without moisture absorption concerns. All parts listed carry MSL Level 1 designation, eliminating moisture sensitivity as a selection criterion and simplifying storage and handling requirements.
