DBLS155G C1G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS155G C1G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 600 V peak reverse voltage and 1.5 A average rectified current. This component is designed for surface mount applications in standard rectification circuits requiring reliable performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including voltage rating, current capacity, forward voltage characteristics, and surface mount packaging specifications.

Substitute Part Grouping Explanation

Substitute parts for the DBLS155G C1G are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
• Operating Temperature Range: -55°C to 150°C (TJ)
• Diode Type: Single Phase
• Technology: Standard

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must satisfy all electrical, mechanical, and compliance parameters. Minor variations in reverse leakage current within the same order of magnitude do not disqualify substitution when all other parameters remain equivalent.

Engineering Selection Recommendations

Primary Part: DBLS155G C1G

The DBLS155G C1G maintains Active product status with full regulatory compliance (RoHS3, REACH Unaffected). This part is suitable for new designs and ongoing production applications requiring single-phase bridge rectification at 600 V / 1.5 A specifications.

Substitute Part: DF1506S-E3/45

The DF1506S-E3/45 manufactured by Vishay General Semiconductor - Diodes Division qualifies as a parametric equivalent. This part maintains identical electrical ratings across voltage, current, and forward voltage specifications. The reverse leakage current specification (10 µA @ 600 V) remains within acceptable tolerance relative to the primary part (2 µA @ 600 V). Both parts share identical mechanical packaging (4-SMD, Gull Wing surface mount), operating temperature range (-55°C to 150°C), and regulatory compliance status (RoHS3 Compliant, REACH Unaffected, MSL 1).

Selection between these parts is determined by availability, supply chain requirements, and procurement specifications. Both parts are suitable for direct substitution in applications where the DBLS155G C1G is specified.

Frequently Asked Questions (FAQ)

Q: Can the DF1506S-E3/45 be used as a direct replacement for the DBLS155G C1G?

A: Yes. The DF1506S-E3/45 meets all critical electrical and mechanical parameters required for substitution. Both parts are rated for 600 V peak reverse voltage, 1.5 A average rectified current, and feature identical 4-SMD Gull Wing surface mount packaging. Regulatory compliance and operating temperature ranges are equivalent.

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

A: The DBLS155G C1G specifies 2 µA reverse leakage at 600 V, while the DF1506S-E3/45 specifies 10 µA at the same conditions. Both values remain within acceptable ranges for standard bridge rectifier applications. This difference does not affect substitution eligibility for circuits designed to the published specifications of either part.

Q: Are the packaging specifications identical between these parts?

A: Yes. Both the DBLS155G C1G and DF1506S-E3/45 use 4-SMD Gull Wing surface mount packaging. PCB layout, reflow soldering profiles, and pick-and-place equipment compatibility are equivalent.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are RoHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). They are suitable for applications requiring full regulatory compliance across industrial and commercial standards.

Q: What is the operating temperature range for both parts?

A: Both the DBLS155G C1G and DF1506S-E3/45 operate across -55°C to 150°C junction temperature (TJ). This range covers standard industrial applications without thermal derating requirements within these limits.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical and mechanical specifications are equivalent, allowing direct substitution in PCB designs, schematics, and bill of materials without circuit modification or re-qualification.
