RDBLS207G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The RDBLS207G is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation. This surface mount component is rated for 1 kV peak reverse voltage with 2 A average rectified current and operates across the temperature range of -55°C to 150°C. The part is classified as Active product status and is ROHS3 compliant. Alternative equivalent parts may be required due to inventory availability, specific automotive qualification requirements, or supply chain considerations while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RDBLS207G are determined by equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Voltage - Peak Reverse (Max): 1 kV
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 2 A
• Current - Reverse Leakage @ Vr: 2 µA @ 1000 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: DBLS
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting these exact specifications are classified as parametric equivalents and direct substitutes. Additional qualifications such as automotive grade certification (AEC-Q101) represent enhanced specifications that do not preclude substitution but indicate suitability for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RDBLS207G, DBLS207G, and DBLS207GH—are parametric equivalents with identical electrical and mechanical specifications. Selection between these parts is based on application requirements and compliance certifications:

RDBLS207G and DBLS207G are suitable for general industrial and commercial applications requiring standard-grade bridge rectifier diodes with 1 kV / 2 A ratings. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification.

DBLS207GH is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. This part is appropriate for automotive applications where component qualification to automotive industry standards is mandated. The electrical and mechanical performance remains identical to the standard-grade equivalents.

Selection should be based on application environment, regulatory requirements, and supply chain availability. All three parts are Active status products suitable for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can DBLS207G be used as a direct replacement for RDBLS207G?

A: Yes. DBLS207G is a parametric equivalent with identical electrical ratings (1 kV / 2 A), forward voltage characteristics (1.15 V @ 2 A), reverse leakage current (2 µA @ 1000 V), operating temperature range (-55°C ~ 150°C), and package configuration (4-SMD, Gull Wing DBLS). Both parts are ROHS3 compliant with MSL 1 classification.

Q: What is the difference between DBLS207G and DBLS207GH?

A: DBLS207GH carries automotive-grade qualification (AEC-Q101) while DBLS207G is standard-grade. All electrical parameters, mechanical specifications, and compliance certifications are identical. DBLS207GH is specified for automotive applications where AEC-Q101 qualification is required.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All three parts use identical 4-SMD, Gull Wing package configuration (DBLS) with the same footprint and mounting requirements. No PCB layout modifications are necessary when substituting between RDBLS207G, DBLS207G, and DBLS207GH.

Q: Do the substitute parts have the same RoHS and REACH compliance status?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. Compliance certifications are identical across all substitute parts.

Q: What is the moisture sensitivity level for these bridge rectifier diodes?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can DBLS207GH be used in non-automotive applications?

A: Yes. DBLS207GH meets or exceeds all specifications required for standard industrial and commercial applications. The automotive qualification represents an additional certification that does not restrict use in non-automotive environments.
