DF06S2 Bridge Rectifier - Equivalent & Substitute Parts

Part Overview

The DF06S2 is a single-phase bridge rectifier manufactured by onsemi, rated for 600 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity. The DF06S2 operates across a temperature range of -55°C to 150°C and is packaged in a 4-SDIP surface mount configuration with gull wing leads.

Substitute Part Grouping Explanation

Substitution of the DF06S2 is determined by strict equivalence across the following critical parameters:

Voltage Rating: Peak reverse voltage must equal 600 V
Current Rating: Average rectified current must equal 2 A
Diode Configuration: Single-phase bridge rectifier topology
Technology: Standard rectifier technology
Mounting and Package: Surface mount, 4-SMD gull wing configuration
Temperature Range: Operating range of -55°C to 150°C
Compliance: ROHS3 compliance and REACH unaffected status

The DF206ST-G manufactured by Comchip Technology meets all these criteria and qualifies as a parametric equivalent substitute.

Engineering Selection Recommendations

The DF206ST-G is a direct parametric equivalent to the DF06S2 across all critical electrical and mechanical specifications. Both components maintain identical voltage and current ratings, temperature operating range, and package configuration. Both are ROHS3 compliant and carry unlimited moisture sensitivity classification.

The DF206ST-G is available in higher inventory quantities (5300 pcs) compared to the DF06S2 (1300 pcs), providing improved procurement availability. Both components are classified as obsolete, indicating that long-term availability should be evaluated against design lifecycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF206ST-G replace the DF06S2 in existing designs?

A: Yes. The DF206ST-G meets all parametric requirements for direct substitution, including voltage rating (600 V), current rating (2 A), temperature range (-55°C to 150°C), and surface mount 4-SMD gull wing package configuration.

Q: What are the differences between these parts?

A: The DF206ST-G has a forward voltage specification at 2 A versus 1 A for the DF06S2, and reverse leakage current of 10 µA compared to 5 µA for the DF06S2. These differences remain within the functional equivalence range for single-phase bridge rectifier applications.

Q: Are there packaging differences?

A: Both components use identical 4-SMD gull wing surface mount packaging. The DF06S2 is supplied in cut tape format, while the DF206ST-G is supplied in tape and reel format. This difference affects procurement and handling but does not impact electrical or mechanical compatibility.

Q: What compliance certifications apply to both parts?

A: Both the DF06S2 and DF206ST-G are ROHS3 compliant, REACH unaffected, and carry ECCN classification EAR99 with HTSUS code 8541.10.0080.
