DB105G Bridge Rectifier Single Phase 600V 1A Equivalent & Substitute Parts

Part Overview

The DB105G is an active single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 600V peak reverse voltage and 1A average rectified current. This component is designed for through-hole mounting applications requiring standard rectification technology in a 4-EDIP package format. The part is RoHS compliant and maintains unlimited moisture sensitivity level (MSL 1), making it suitable for general industrial and commercial applications.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter ranges for this product category, while maintaining compatible mechanical form factors and mounting characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DB105G are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Voltage - Peak Reverse (Max): Must equal 600V
• Diode Type: Must be Single Phase
• Technology: Must be Standard
• Mounting Type: Must be Through Hole
• Package / Case: Must be 4-EDIP (0.321", 8.15mm)
• Operating Temperature Range: Must encompass -55°C to 150°C

Allowable Variation Parameters:

• Current - Average Rectified (Io): May exceed 1A (higher current rating is acceptable for lower-current applications)
• Voltage - Forward (Vf): May vary within standard rectifier specifications
• Current - Reverse Leakage: May be equal to or lower than specified value

The DF206-G from Comchip Technology qualifies as a substitute because it maintains identical voltage ratings, diode type, technology classification, mounting method, and package format. The higher current rating (2A versus 1A) does not prevent substitution, as components with higher current capacity can operate within lower current requirements.

Parameter Comparison

Engineering Selection Recommendations

DB105G Selection Criteria: The DB105G remains the primary choice when GeneSiC Semiconductor sourcing is required or when the 1A current specification is specifically matched to circuit design parameters. This part maintains active product status and RoHS compliance.

DF206-G Selection Criteria: The DF206-G from Comchip Technology is electrically and mechanically compatible for applications currently using the DB105G. The higher 2A current rating provides operational margin in circuits designed for 1A rectification. This substitute maintains ROHS3 compliance and identical thermal operating range. Selection of DF206-G is appropriate when Comchip Technology sourcing is preferred, when component availability from GeneSiC is constrained, or when the higher current capacity provides design flexibility.

Both parts share identical voltage specifications, package geometry, mounting method, and temperature operating range. The substitution is valid based on electrical parameter equivalence and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can DF206-G replace DB105G in existing circuit designs?

A: Yes. The DF206-G maintains identical peak reverse voltage (600V), forward voltage characteristics (1.1V), reverse leakage current (10µA @ 600V), operating temperature range (-55°C to 150°C), and physical package dimensions (4-EDIP, 0.321", 8.15mm). The higher current rating (2A) does not prevent operation in 1A applications.

Q: What is the significance of the current rating difference between these parts?

A: The DB105G is rated for 1A average rectified current, while the DF206-G is rated for 2A. A substitute with higher current capacity can safely operate at lower current levels. The DF206-G will function correctly in circuits designed for 1A operation.

Q: Are the package dimensions identical?

A: Yes. Both the DB105G and DF206-G use the 4-EDIP package format with dimensions of 0.321" (8.15mm). Both are through-hole mounted components with identical pin configurations and board layout compatibility.

Q: What compliance certifications apply to each part?

A: The DB105G holds RoHS Compliant certification. The DF206-G holds ROHS3 Compliant certification. Both parts maintain MSL 1 (Unlimited) moisture sensitivity level. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Are there any thermal operating range differences?

A: No. Both parts operate across the identical temperature range of -55°C to 150°C (TJ).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. The identical package format, pin configuration, and mounting type (through-hole) allow direct substitution on printed circuit boards without layout modifications.
