DFB2060 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DFB2060 is a single-phase bridge rectifier manufactured by onsemi, rated for 600 V peak reverse voltage and 20 A average rectified current in a through-hole TS-6P package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original component is no longer readily available or when design flexibility permits alternative sourcing.

Key Parameters

Parameter	Value

Current - Reverse Leakage @ Vr	10 µA @ 600 V
Operating Temperature Range	-55°C ~ 150°C (TJ)
Mounting Type	Through Hole
Package / Case	4-SIP, TS-6P
RoHS Status	ROHS3 Compliant

Substitute Part Grouping Explanation

Substitution eligibility for the DFB2060 is determined by the following critical parameters:

Voltage Rating: Peak reverse voltage must be 600 V or greater
Current Rating: Average rectified current must be 20 A or greater
Diode Type: Single-phase bridge rectifier configuration
Package Compatibility: Through-hole mounting with compatible pinout (TS-6P or equivalent 4-SIP)
Operating Temperature: Range must encompass -55°C to 150°C
Compliance: RoHS3 compliance required for regulatory alignment

The substitute parts identified below meet all these criteria and are therefore electrically and mechanically interchangeable with the DFB2060 in applications where the original component is unavailable.

Engineering Selection Recommendations

Parametric Equivalents (Preferred for Direct Replacement):

TS20P05G and TS20P05G C2G, both manufactured by Taiwan Semiconductor Corporation, are parametric equivalents to the DFB2060. These parts maintain identical electrical specifications across all critical parameters, including forward voltage, reverse leakage current, and thermal operating range. Both are in active production status with ROHS3 compliance and REACH unaffected certification. The TS20P05G C2G variant offers significantly higher inventory availability (12,173 pcs) compared to TS20P05G (3,422 pcs), making it the preferred choice for immediate procurement.

Functional Substitute (Alternative with Minor Derating):

GBJ2006, manufactured by HY Electronic (Cayman) Limited, functions as a substitute with acceptable parameter variations. The forward voltage specification is lower (1 V @ 10 A versus 1.1 V @ 20 A), and reverse leakage is reduced (5 µA @ 600 V versus 10 µA @ 600 V), both favorable characteristics. The GBJ package differs from TS-6P, requiring mechanical verification of board layout compatibility. GBJ2006 is in active production with ROHS3 compliance. Inventory availability is 2,222 pcs.

For applications requiring immediate replacement with maximum compatibility assurance, TS20P05G C2G is the optimal selection. For applications where package flexibility exists, GBJ2006 provides an alternative with improved leakage characteristics.

Frequently Asked Questions (FAQ)

Q: Can TS20P05G and TS20P05G C2G be used interchangeably with DFB2060?

A: Yes. Both Taiwan Semiconductor parts are parametric equivalents with identical electrical specifications for voltage rating, current capacity, forward voltage, reverse leakage, and operating temperature range. They are direct replacements in the TS-6P package configuration.

Q: What is the difference between TS20P05G and TS20P05G C2G?

A: Both parts are electrically identical. The designation "C2G" indicates a specific manufacturing or packaging variant. Selection between them should be based on availability and procurement lead time. TS20P05G C2G has higher current inventory stock.

Q: Is GBJ2006 a direct replacement for DFB2060?

A: GBJ2006 is a functional substitute meeting all critical electrical parameters (600 V, 20 A, -55°C to 150°C). However, the package differs (GBJ versus TS-6P). Board layout compatibility must be verified before substitution. The improved forward voltage and leakage characteristics make it suitable for applications where package modification is acceptable.

Q: What parameters must remain constant for substitution?

A: Peak reverse voltage (600 V minimum), average rectified current (20 A minimum), single-phase bridge configuration, through-hole mounting, and operating temperature range (-55°C to 150°C) are non-negotiable. RoHS3 compliance is required for regulatory alignment.

Q: Why is DFB2060 marked "Not For New Designs"?

A: This status indicates the component has reached end-of-life and is no longer recommended for new product development. Existing inventory remains available for legacy system support and repair applications. Active alternatives such as TS20P05G C2G should be specified for new designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. DFB2060, TS20P05G, TS20P05G C2G, and GBJ2006 are all ROHS3 compliant, ensuring regulatory compatibility across all options.
