DB153S Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DB153S is a single-phase bridge rectifier manufactured by SMC Diode Solutions, rated for 200 V peak reverse voltage and 1.5 A average rectified current. This surface mount component operates across the temperature range of -55°C to 150°C and is packaged in a 4-SMD, Gull Wing configuration. The part is currently in active production status with 921 pieces available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the critical parameters that define bridge rectifier functionality. Alternative sources may be required due to supply chain considerations, inventory availability, or design phase requirements.

Key Parameters

Parameter	Value
Voltage - Peak Reverse (Max)	200 V
Current - Average Rectified (Io)	1.5 A
Voltage - Forward (Vf) (Max) @ If	1.1 V @ 1.5 A
Operating Temperature Range	-55°C ~ 150°C (TJ)
Mounting Type	Surface Mount
Package / Case	4-SMD, Gull Wing
RoHS Status	ROHS3 Compliant

Substitute Part Grouping Explanation

Substitution eligibility for the DB153S is determined by matching the following critical parameters:

Voltage - Peak Reverse (Max): 200 V
Current - Average Rectified (Io): 1.5 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
Operating Temperature Range: -55°C ~ 150°C (TJ)
Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing
Diode Type: Single Phase
Technology: Standard

Parts meeting these electrical and mechanical specifications are classified as parametric equivalents. Variations in reverse leakage current, packaging format (Tape & Reel vs. Cut Tape), and product status do not disqualify substitution when the primary electrical ratings and thermal operating range remain identical.

Engineering Selection Recommendations

DB153S (SMC Diode Solutions): Recommended for new designs. Active product status ensures continued manufacturing support and supply chain stability. ROHS3 compliant with REACH affected status.

DF02S (onsemi): Parametric equivalent with identical electrical specifications. Product status is "Not For New Designs," indicating this part is in mature phase with limited future availability. Suitable for legacy system maintenance or replacement applications where supply from active sources is constrained. ROHS3 compliant with REACH unaffected status.

DF1502S-E3/77 (Vishay General Semiconductor - Diodes Division): Parametric equivalent with active product status. Identical electrical performance to DB153S with matching reverse leakage specification. ROHS3 compliant with REACH unaffected status. Suitable for new designs as an alternative source.

Frequently Asked Questions (FAQ)

Q: Can DF02S be used as a direct replacement for DB153S in new designs?

A: DF02S meets all electrical and mechanical specifications for functional equivalence. However, its "Not For New Designs" status indicates limited future manufacturing support. For new designs, DF1502S-E3/77 is the preferred alternative.

Q: What is the significance of the reverse leakage current difference between DB153S (5 µA) and DF02S (10 µA)?

A: Both values fall within acceptable operating parameters for single-phase bridge rectifier applications at 200 V. The difference does not affect substitution eligibility for standard rectification circuits.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts share identical package specifications: 4-SMD, Gull Wing configuration with surface mount mounting type. PCB layout and footprint design remain unchanged across substitutions.

Q: What packaging formats are available for these parts?

A: DB153S and DF1502S-E3/77 are supplied in Tape & Reel (TR) format. DF02S is available in Cut Tape (CT) and Digi-Reel® format. Packaging format does not affect electrical performance or PCB assembly compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. DB153S, DF02S, and DF1502S-E3/77 are all ROHS3 compliant, meeting environmental and hazardous substance restrictions.
