DB152S Bridge Rectifier Single Phase 100V 1.5A Equivalent & Substitute Parts

Part Overview

The DB152S is a single-phase bridge rectifier manufactured by SMC Diode Solutions, rated for 100V peak reverse voltage and 1.5A average rectified current. This component is classified as Active product status and is RoHS3 compliant. Bridge rectifiers in this specification range are essential for AC-to-DC conversion applications requiring surface mount integration with standard rectification technology. Substitute parts become necessary when addressing supply chain constraints, packaging preferences, or design revision requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the DB152S is determined by strict equivalence across the following critical parameters:

Diode Type: Single Phase
Technology: Standard
Voltage - Peak Reverse (Max): 100 V
Current - Average Rectified (Io): 1.5 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
Current - Reverse Leakage @ Vr: 5 µA @ 100 V
Operating Temperature Range: -55°C ~ 150°C (TJ)
Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing

All identified substitute parts meet these electrical and mechanical requirements. Variations in supplier device package designation, manufacturer, and product status do not affect functional equivalence within the specified parameter set.

Engineering Selection Recommendations

DF1501S-E3/77 (Vishay General Semiconductor - Diodes Division) is the primary substitute for new designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It carries ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements equivalent to the DB152S.

DF01S (onsemi) is a parametric equivalent with identical electrical specifications and surface mount configuration. However, this part is designated Not For New Designs, limiting its application to legacy system maintenance or replacement scenarios where existing inventory must be sustained. The DF01S remains electrically and mechanically compatible with the DB152S across all specified parameters.

Both substitute parts are available in production quantities and maintain the same 4-SMD Gull Wing package configuration required for PCB integration.

Frequently Asked Questions (FAQ)

Q: Can DF01S and DF1501S-E3/77 be used interchangeably with DB152S?

A: Yes. Both parts meet all specified electrical parameters: 100V peak reverse voltage, 1.5A average rectified current, 1.1V forward voltage drop at 1.5A, and 5µA reverse leakage at 100V. All three components use identical 4-SMD Gull Wing surface mount packaging and operate across the -55°C to 150°C temperature range.

Q: What is the difference between the substitute parts?

A: DF1501S-E3/77 maintains Active product status, while DF01S is designated Not For New Designs. Both are RoHS3 compliant and MSL Level 1. The primary distinction is manufacturer (Vishay versus onsemi) and long-term availability commitment.

Q: Are there packaging differences between these parts?

A: All three parts use 4-SMD Gull Wing surface mount packages. Supplier device package designations differ (DB-S, 4-SDIP, and DFS respectively), but the physical footprint and PCB mounting requirements are identical.

Q: Do these parts require different PCB layout considerations?

A: No. The 4-SMD Gull Wing package configuration is standardized across all three parts. PCB footprints, trace routing, and thermal management requirements remain unchanged.

Q: What compliance certifications apply to all substitute options?

A: All three parts are RoHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. ECCN classification is EAR99 for all parts. HTSUS code 8541.10.0080 applies uniformly.
