Substitute Part Grouping Explanation

Substitution eligibility for the GSIB2040-E3/45 is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 400 V
• Current - Average Rectified (Io): 3.5 A
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-SIP, GSIB-5S

The GSIB2540-E3/45 meets all substitution criteria. Both parts share identical voltage ratings, current specifications, temperature operating range, mounting configuration, and package type. Forward voltage characteristics differ slightly (1 V @ 12.5 A for the substitute versus 1 V @ 10 A for the main part), but this represents a measurement condition variation rather than a functional limitation. Reverse leakage current remains constant at 10 µA @ 400 V. Both parts maintain ROHS3 compliance and MSL Level 1 classification.

Parameter Comparison

Engineering Selection Recommendations

Both the GSIB2040-E3/45 and GSIB2540-E3/45 are active products from Vishay General Semiconductor - Diodes Division with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and supply chain requirements. The GSIB2540-E3/45 offers higher current inventory (2040 units versus 1170 units), which may provide supply chain advantages. Both parts maintain identical electrical performance across all critical parameters: 400 V peak reverse voltage, 3.5 A average rectified current, and -55°C to 150°C operating temperature range. Package configuration, mounting type, and compliance certifications are identical, ensuring direct functional interchangeability in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the GSIB2540-E3/45 be used as a direct replacement for the GSIB2040-E3/45?

A: Yes. Both parts are single-phase bridge rectifiers with identical voltage ratings (400 V), current specifications (3.5 A), operating temperature range (-55°C to 150°C), and package configuration (4-SIP, GSIB-5S through-hole). They are functionally equivalent for circuit applications.

Q: What is the difference in forward voltage specifications between these parts?

A: The forward voltage is specified at different measurement conditions. The GSIB2040-E3/45 is rated at 1 V @ 10 A, while the GSIB2540-E3/45 is rated at 1 V @ 12.5 A. Both maintain the same maximum forward voltage of 1 V, with the difference reflecting the test current level rather than a functional performance variation.

Q: Are both parts RoHS compliant?

A: Yes. Both the GSIB2040-E3/45 and GSIB2540-E3/45 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the package type for these bridge rectifiers?

A: Both parts use a 4-SIP (Single In-line Package) configuration designated as GSIB-5S. This is a through-hole mounting package suitable for standard PCB assembly processes.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity limitations for storage or handling.
