DB107G Bridge Rectifier Single Phase 1 kV 1 A Equivalent & Substitute Parts

Part Overview

The DB107G is an active single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 1 kV peak reverse voltage and 1 A average rectified current. This component is designed for through-hole mounting applications requiring standard rectification technology in a 4-EDIP package configuration. The part is RoHS compliant and carries an unlimited moisture sensitivity level rating, indicating suitability for standard storage and handling conditions.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when application requirements permit operation with higher current ratings while maintaining electrical compatibility across critical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the DB107G is based on electrical and mechanical parameter compatibility within the single-phase bridge rectifier category. The following criteria determine valid substitutes:

Mandatory Matching Parameters:

• Voltage - Peak Reverse (Max): 1 kV minimum
• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)
• Diode Type: Single Phase
• Technology: Standard
• Operating Temperature Range: -55°C to 150°C (TJ) minimum

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitutes with equal or higher ratings are acceptable, provided the application circuit can accommodate increased current capacity
• Voltage - Forward (Vf): Substitutes with equal or lower forward voltage drop are acceptable
• Current - Reverse Leakage: Substitutes with equal or lower leakage current are acceptable
• RoHS/Regulatory Status: Substitutes must maintain or exceed compliance level

The DF210-G qualifies as a valid substitute based on these criteria, with the primary difference being an increased current rating of 2 A versus the original 1 A specification.

Engineering Selection Recommendations

DB107G Selection Criteria:

• Primary choice when GeneSiC Semiconductor sourcing is required
• Suitable for applications with maximum 1 A average rectified current requirement
• RoHS compliant for regulated environments
• Active product status ensures continued availability and technical support

DF210-G Selection Criteria:

• Valid substitute when current capacity of 2 A is acceptable or beneficial
• Comchip Technology manufacturing provides alternative supply chain
• ROHS3 compliance exceeds DB107G RoHS standard
• Tube packaging format differs from bulk packaging of original part
• Identical electrical performance at equivalent operating points
• Higher current rating provides design margin without electrical incompatibility

Both parts maintain identical voltage ratings, temperature ranges, forward voltage characteristics, and reverse leakage specifications. Selection between these parts depends on supply availability, packaging requirements, and whether the increased current capacity of the DF210-G aligns with circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can the DF210-G directly replace the DB107G in existing circuit boards?

A: Yes. Both components share identical package dimensions (4-EDIP, 0.321", 8.15mm), through-hole mounting configuration, and electrical specifications at their respective rated currents. Pin-to-pin compatibility is maintained.

Q: What is the significance of the 2 A rating on the DF210-G versus the 1 A rating on the DB107G?

A: The DF210-G is rated for twice the average rectified current. In applications designed for 1 A operation, the DF210-G operates with additional current capacity margin. This does not create incompatibility; it represents a higher-rated component suitable for the same voltage and temperature requirements.

Q: Are the forward voltage drops identical between these parts?

A: Both parts specify 1.1 V maximum forward voltage drop at their rated currents (1 A for DB107G, 2 A for DF210-G). At equivalent operating points within the 1 A range, forward voltage characteristics are equivalent.

Q: Does packaging format (Bulk vs. Tube) affect electrical performance?

A: No. Packaging format affects only handling, storage, and ordering quantities. Electrical and mechanical specifications remain identical regardless of whether components are supplied in bulk or tube packaging.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents a more recent revision of RoHS standards with updated substance restrictions. The DF210-G's ROHS3 compliance exceeds the RoHS compliance of the DB107G, making it suitable for applications requiring the latest regulatory standards.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts maintain identical operating temperature ranges of -55°C to 150°C (TJ). Temperature performance is equivalent across the specified range.

Q: What is the reverse leakage current specification, and is it important for substitution?

A: Both parts specify 10 µA maximum reverse leakage at 1000 V. This parameter is equivalent between the two components and does not affect substitution decisions.
