Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GSIB6A40N-M3/45 is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): Must equal 400 V
• Diode Type: Must be Single Phase
• Technology: Must be Standard
• Mounting Type: Must be Through Hole
• Package / Case: Must be 4-SIP, GSIB-5S
• Operating Temperature Range: Must support -55°C ~ 150°C (TJ)

Current - Average Rectified (Io) and forward voltage characteristics may vary within the substitute parts, provided the peak reverse voltage, package format, and thermal operating range remain constant. This allows for both higher and lower current-rated alternatives within the same physical and electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compliance with ROHS3, REACH Unaffected, and MSL 1 (Unlimited) specifications, ensuring regulatory and environmental compatibility with the original GSIB6A40N-M3/45.

GSIB640N-M3/45 is classified as MFR Recommended and carries Active product status. This part is suitable for applications where the 15 A current rating of the original part exceeds system requirements. The 6 A average rectified current rating provides adequate capacity for lower-current designs while maintaining identical voltage and thermal specifications.

GSIB15A40N-M3/45 is classified as Parametric Equivalent and carries Active product status. This part maintains the original 15 A current rating and is suitable for direct replacement in applications requiring the full current capacity of the GSIB6A40N-M3/45. The forward voltage characteristic at 7.5 A provides performance data at higher current levels compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can GSIB640N-M3/45 be used in place of GSIB6A40N-M3/45?

A: GSIB640N-M3/45 is electrically compatible for applications where the circuit current demand does not exceed 6 A average rectified current. Both parts share identical 400 V peak reverse voltage, -55°C to 150°C operating temperature range, and 4-SIP GSIB-5S package format. Selection depends on actual circuit current requirements.

Q: What is the difference between the two substitute parts?

A: GSIB640N-M3/45 is rated for 6 A average rectified current, while GSIB15A40N-M3/45 maintains the original 15 A rating. Both are manufactured by Vishay and share all other electrical and mechanical specifications. Choose based on your application's current requirements.

Q: Are the substitute parts physically interchangeable?

A: Yes. Both substitute parts use the identical 4-SIP GSIB-5S through-hole package format, enabling direct mechanical substitution on existing PCB layouts without modification.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both GSIB640N-M3/45 and GSIB15A40N-M3/45 are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) ratings, matching the original part's regulatory status.

Q: Why is the original GSIB6A40N-M3/45 marked as obsolete?

A: Product obsolescence is determined by the manufacturer. Active substitute parts with identical electrical and mechanical specifications are available to support continued design implementation and production requirements.
