DBLS152G RDG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS152G RDG is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 100 V peak reverse voltage and 1.5 A average rectified current. This component operates across the temperature range of -55°C to 150°C and is packaged in a 4-SMD, Gull Wing surface mount configuration. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when electrical parameters and mechanical specifications align within the allowed tolerances for bridge rectifier applications. The DBLS152G RDG has two parametric equivalents available: the DF1501S-E3/77 from Vishay General Semiconductor and the DF01S from onsemi.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBLS152G RDG is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Peak Reverse (Max): 100 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)
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Diode Type: Single Phase
• Technology: Standard

Both identified substitute parts meet these core electrical specifications. Variations in reverse leakage current (2 µA to 5 µA @ 100 V) remain within acceptable operational tolerances for bridge rectifier applications. Packaging format (supplier device package designation) and product status differ between alternatives but do not affect electrical interchangeability when mechanical footprint compatibility is confirmed.

Engineering Selection Recommendations

DF1501S-E3/77 (Vishay General Semiconductor - Diodes Division)

The DF1501S-E3/77 maintains Active product status and is suitable for new design implementations. This part is supplied in Tape & Reel (TR) packaging format and carries identical electrical specifications to the DBLS152G RDG. All compliance certifications (RoHS3, REACH Unaffected, EAR99) align with the main part. The reverse leakage current specification of 5 µA @ 100 V is within acceptable operational tolerance. Inventory availability is 6700 pieces.

DF01S (onsemi)

The DF01S is designated as Not For New Designs and carries a legacy product status. While electrical parameters match the DBLS152G RDG specification, this part is supplied in Cut Tape (CT) & Digi-Reel® packaging. All compliance certifications remain equivalent. The reverse leakage current specification of 5 µA @ 100 V is within acceptable operational tolerance. Inventory availability is 6258 pieces. This part is suitable for replacement or repair applications only.

For new design implementations, the DF1501S-E3/77 is the preferred substitute. For legacy system maintenance or repair, the DF01S remains electrically compatible.

Frequently Asked Questions (FAQ)

Q: What determines if a bridge rectifier can substitute for the DBLS152G RDG?

A: Substitution is valid when the following parameters match: Peak Reverse Voltage (100 V), Average Rectified Current (1.5 A), Forward Voltage (1.1 V @ 1.5 A), Operating Temperature Range (-55°C to 150°C), Mounting Type (Surface Mount), Package Configuration (4-SMD, Gull Wing), Diode Type (Single Phase), and Technology (Standard). Both identified substitutes meet these requirements.

Q: Are there differences in reverse leakage current between the main part and substitutes?

A: The DBLS152G RDG specifies 2 µA @ 100 V reverse leakage, while both DF1501S-E3/77 and DF01S specify 5 µA @ 100 V. This difference remains within acceptable operational tolerance for standard bridge rectifier applications and does not affect electrical interchangeability.

Q: What is the difference between the two substitute parts?

A: The DF1501S-E3/77 and DF01S are electrically identical but differ in product status and packaging format. The DF1501S-E3/77 is Active and supplied in Tape & Reel format, suitable for new designs. The DF01S is designated Not For New Designs and supplied in Cut Tape & Digi-Reel format, suitable for legacy system maintenance.

Q: Can I use the DF01S in a new design?

A: The DF01S carries a Not For New Designs designation. For new design implementations, the DF1501S-E3/77 is the recommended substitute. The DF01S is suitable for replacement or repair of existing systems only.

Q: Are all three parts RoHS3 compliant?

A: Yes. The DBLS152G RDG, DF1501S-E3/77, and DF01S are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status.

Q: Do the substitute parts have the same physical footprint?

A: Yes. All three parts use the 4-SMD, Gull Wing package configuration, ensuring mechanical compatibility on PCB layouts designed for the DBLS152G RDG.

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

A: All three parts operate across the identical temperature range of -55°C to 150°C (TJ), ensuring thermal compatibility in equivalent applications.
