DB152L-BP Bridge Rectifier Single Phase 100V 1.5A Equivalent & Substitute Parts

Part Overview

The DB152L-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for through-hole mounting applications requiring 100V peak reverse voltage and 1.5A average rectified current. This component operates across a wide temperature range of -55°C to 150°C and features a 4-EDIP package configuration.

The DB152L-BP carries a "Not For New Designs" product status, indicating that this part is no longer recommended for new circuit development. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and transition to actively supported alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB152L-BP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• 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
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Equivalence Requirements:

• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)

The DB152G manufactured by GeneSiC Semiconductor satisfies all electrical and mechanical equivalence criteria. While the DB152G exhibits superior reverse leakage characteristics (5 µA @ 100 V versus 10 µA @ 100 V), this represents an improvement that does not compromise compatibility. The DB152G maintains identical forward voltage, current rating, voltage rating, temperature range, and physical package configuration.

Engineering Selection Recommendations

DB152G Selection Rationale:

The DB152G is the direct equivalent substitute for the DB152L-BP. This substitution is supported by:

1. Electrical Compatibility: All critical electrical parameters match exactly, including voltage rating, current capacity, forward voltage drop, and operating temperature range.

2. Mechanical Compatibility: Both components utilize identical 4-EDIP through-hole packaging with matching pin spacing (0.321", 8.15mm), ensuring direct PCB footprint compatibility without layout modifications.

3. Product Status Advantage: The DB152G carries "Active" product status, indicating ongoing manufacturer support, continued availability, and compliance with current industry standards. This contrasts with the DB152L-BP's "Not For New Designs" designation.

4. Compliance Certification: The DB152G is RoHS Compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited), providing enhanced environmental and reliability documentation suitable for regulated applications.

5. Performance Improvement: The DB152G demonstrates superior reverse leakage characteristics (5 µA @ 100 V), representing a 50% reduction compared to the DB152L-BP specification. This improvement enhances circuit reliability without introducing any compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can the DB152G be used as a direct replacement for the DB152L-BP without PCB modifications?

A: Yes. The DB152G is mechanically and electrically equivalent to the DB152L-BP. Both components feature identical 4-EDIP through-hole packaging with matching pin configurations and spacing. No PCB layout changes are required for substitution.

Q: What is the significance of the "Not For New Designs" status on the DB152L-BP?

A: This designation indicates that Micro Commercial Co no longer recommends the DB152L-BP for new circuit development. Existing designs may continue to use this part, but new applications should transition to actively supported alternatives such as the DB152G to ensure long-term supply chain stability and manufacturer support.

Q: Are there performance differences between the DB152L-BP and DB152G?

A: Both components meet identical electrical specifications for voltage rating, current capacity, and forward voltage. The DB152G exhibits lower reverse leakage current (5 µA versus 10 µA at 100V), which represents an improvement in performance characteristics. This difference does not affect compatibility and may enhance circuit reliability.

Q: Does the DB152G meet RoHS compliance requirements?

A: Yes. The DB152G is RoHS Compliant and carries Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating compliance with environmental and reliability standards. The DB152L-BP does not specify RoHS status in the provided documentation.

Q: What package configuration do these components use?

A: Both the DB152L-BP and DB152G use 4-EDIP (0.321", 8.15mm) through-hole packaging. This configuration provides four connection points suitable for single-phase bridge rectifier applications and is compatible with standard through-hole PCB assembly processes.

Q: Can the DB152G handle the same temperature range as the DB152L-BP?

A: Yes. Both components operate across the identical temperature range of -55°C to 150°C (TJ), ensuring equivalent thermal performance in applications requiring extended temperature operation.
