DB152G Bridge Rectifier Single Phase 100V 1.5A Equivalent & Substitute Parts

Part Overview

The DB152G is a single-phase bridge rectifier diode manufactured by GeneSiC Semiconductor, rated for 100V peak reverse voltage and 1.5A average rectified current. This component is classified as Active product status and is RoHS Compliant. Bridge rectifiers are essential in AC-to-DC conversion applications, providing full-wave rectification in power supply circuits. Substitute parts become necessary when the primary component experiences supply constraints, obsolescence concerns, or when design flexibility requires alternative sourcing from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the DB152G is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

Voltage - Peak Reverse (Max): 100V (exact match required)
Diode Type: Single Phase (exact match required)
Technology: Standard (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: 4-EDIP form factor (mechanical compatibility required)

Secondary Compatibility Factors:

Current - Average Rectified (Io): Substitute must equal or exceed 1.5A
Voltage - Forward (Vf): Must not exceed 1.1V at rated current
Current - Reverse Leakage: Lower values indicate superior performance
Operating Temperature Range: Must encompass or exceed -55°C to 150°C
RoHS Compliance: Preferred for regulatory alignment

Identified Substitutes:

The DB102-BP (Micro Commercial Co) qualifies as a substitute with the following constraint: Current rating is 1 A, which is lower than the DB152G's 1.5 A specification. This part is suitable only for applications where the actual load current does not exceed 1 A.

The DF01M (Fairchild Semiconductor) qualifies as a substitute with the following constraint: Current rating is 1 A, which is lower than the DB152G's 1.5 A specification. This part is suitable only for applications where the actual load current does not exceed 1 A. Additionally, the package dimensions differ slightly (0.300" vs 0.321"), requiring PCB layout verification.

Engineering Selection Recommendations

DB152G (Primary Component): Select the DB152G when full 1.5A current capacity is required and Active product status with continuous manufacturer support is essential. This component offers the lowest reverse leakage current (5 µA) among the three options, indicating superior performance in low-leakage applications. RoHS Compliance status is confirmed.

DB102-BP (Substitute with Limitations): The DB102-BP is suitable only for applications where the actual load current does not exceed 1 A. This part carries "Not For New Designs" status, indicating it is in mature or declining production phase. Use only when supply of the primary component is unavailable and current requirements permit the lower rating. ROHS3 Compliance is confirmed. Higher reverse leakage (10 µA) may impact performance in sensitive analog circuits.

DF01M (Substitute with Limitations): The DF01M is suitable only for applications where the actual load current does not exceed 1 A. This part maintains Active product status and offers extended lower operating temperature range (-65°C vs -55°C). Package dimensions differ slightly (0.300" vs 0.321"), requiring verification that PCB footprint accommodates the smaller package. Higher reverse leakage (10 µA) may impact performance in sensitive analog circuits. RoHS status is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can DB102-BP or DF01M be used as direct replacements for DB152G in all applications?

A: No. Both substitute parts are rated for 1 A average rectified current, while the DB152G is rated for 1.5 A. Substitution is valid only when the actual circuit load current does not exceed 1 A. Exceeding this limit will cause component failure or reduced reliability.

Q: What is the significance of the "Not For New Designs" status on DB102-BP?

A: This designation indicates the part is in mature production phase with no active development or enhancement. While existing inventory is available, manufacturers typically do not guarantee long-term supply or introduce design improvements. For new product development, DB152G or DF01M are preferred.

Q: Are the package dimensions of DF01M compatible with DB152G PCB layouts?

A: The DF01M package measures 0.300" (7.62mm) while DB152G measures 0.321" (8.15mm). Both use 4-EDIP form factor, but the dimensional difference requires PCB footprint verification. Existing PCB layouts designed for DB152G may require modification to accommodate DF01M.

Q: How do reverse leakage current differences affect circuit performance?

A: DB152G specifies 5 µA reverse leakage at 100V, while both DB102-BP and DF01M specify 10 µA. In high-impedance analog circuits, power supplies with precision filtering, or applications sensitive to leakage current, the lower leakage of DB152G provides superior performance. In standard power supply applications, this difference is typically negligible.

Q: Which substitute offers the best temperature performance?

A: DF01M provides the widest operating temperature range (-65°C to 150°C) compared to DB152G and DB102-BP (both -55°C to 150°C). For applications requiring operation below -55°C, DF01M is the only qualified option among the three parts.

Q: What packaging format differences exist between these parts?

A: DB152G is supplied in Bulk packaging, DB102-BP in Tube packaging, and DF01M in Bulk packaging. Packaging format affects handling, storage, and integration into automated assembly processes but does not impact electrical performance or functionality.

Q: Are all three parts RoHS compliant?

A: DB152G is RoHS Compliant and DB102-BP is ROHS3 Compliant. DF01M RoHS status is not specified in the provided documentation. For applications requiring confirmed RoHS compliance, DB152G or DB102-BP are the appropriate selections.
