DBF10TG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBF10TG is a single-phase bridge rectifier manufactured by onsemi, rated for 600 V peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. Bridge rectifiers in this voltage and current class are fundamental components in AC-to-DC conversion applications requiring through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DBF10TG is determined by the following critical parameters:

• Voltage Rating: Peak reverse voltage must be 600 V or greater to maintain circuit protection margins
• Current Rating: Average rectified current must meet or exceed 1 A to handle design load requirements
• Diode Type & Technology: Single-phase standard bridge rectifier topology
• Mounting Type: Through-hole configuration for PCB compatibility
• Package Form Factor: 4-SIP package family (DBF or KBP variants)
• Forward Voltage Characteristics: Maximum forward voltage drop at rated current
• Reverse Leakage: Maximum reverse leakage current at rated voltage
• Operating Temperature Range: Junction temperature capability of 150°C minimum

The KBP06G meets all substitution criteria with equivalent or superior electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The KBP06G is a direct functional substitute for the DBF10TG based on the following factors:

• Voltage and Current Ratings: The KBP06G maintains the 600 V peak reverse voltage specification and exceeds the 1 A current requirement at 1.5 A, providing design margin
• Electrical Performance: Forward voltage and reverse leakage characteristics are within comparable ranges for standard bridge rectifier technology
• Product Status: The KBP06G is an active product with established supply chain availability, addressing the obsolescence of the DBF10TG
• Compliance: The KBP06G carries ROHS3 compliance certification, meeting modern regulatory requirements
• Package Compatibility: Both components use 4-SIP through-hole packages within the same family, supporting direct PCB layout compatibility
• Temperature Range: The KBP06G supports the required 150°C junction temperature with extended lower temperature capability

Frequently Asked Questions (FAQ)

Q: Can the KBP06G directly replace the DBF10TG in existing designs?

A: Yes. Both components are single-phase bridge rectifiers with identical 600 V voltage ratings, through-hole 4-SIP package mounting, and compatible electrical characteristics. The KBP06G's higher 1.5 A current rating and lower reverse leakage provide equivalent or improved performance.

Q: What are the package differences between DBF and KBP variants?

A: Both DBF and KBP are 4-SIP through-hole package families used for single-phase bridge rectifiers. The physical form factor is compatible for PCB mounting, though specific lead spacing should be verified against PCB footprint documentation.

Q: Does the KBP06G meet environmental and compliance requirements?

A: The KBP06G is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, meeting modern environmental and regulatory standards. The DBF10TG specifications do not include RoHS status documentation.

Q: Are there current rating implications when substituting?

A: The KBP06G is rated for 1.5 A average rectified current compared to the DBF10TG's 1 A rating. This higher rating provides design margin and does not create compatibility issues in applications designed for 1 A operation.

Q: What is the significance of reverse leakage current differences?

A: The KBP06G exhibits 5 µA reverse leakage at 600 V compared to the DBF10TG's 10 µA. Lower reverse leakage improves circuit efficiency and is beneficial in high-impedance applications, with no negative impact on standard rectification circuits.
