Parameter Comparison

Engineering Selection Recommendations

The BAS40XY,115 is the direct equivalent substitute for the obsolete BAS40XYF. Both components are manufactured by Nexperia USA Inc. and share identical electrical and mechanical specifications across all critical parameters.

Selection Basis:

The BAS40XY,115 is classified as active product status, ensuring ongoing availability and supply chain continuity. The component maintains full automotive grade qualification under AEC-Q100 certification, meeting the same reliability and quality standards as the original BAS40XYF (AEC-Q101).

All electrical parameters—including reverse voltage rating (40 V), rectified current capacity (120 mA per diode), forward voltage drop (1 V @ 40 mA), reverse leakage current (10 µA @ 40 V), and junction temperature rating (150°C)—are identical between the two parts.

The 6-TSSOP surface mount package is identical, enabling direct board-level substitution without PCB redesign or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can BAS40XY,115 be used as a direct replacement for BAS40XYF in existing designs?

A: Yes. The BAS40XY,115 is electrically and mechanically identical to the BAS40XYF across all specified parameters. Direct substitution is supported without circuit modification or performance degradation.

Q: What is the difference between AEC-Q100 and AEC-Q101 qualifications?

A: Both qualifications establish automotive-grade reliability standards. AEC-Q100 applies to discrete semiconductors, while AEC-Q101 applies to optoelectronic devices. For this Schottky diode array, both certifications confirm compliance with automotive quality and reliability requirements.

Q: Are the package dimensions identical between BAS40XYF and BAS40XY,115?

A: Yes. Both components use the 6-TSSOP (SC-88, SOT-363) surface mount package with identical pinout, footprint, and mechanical dimensions. No PCB layout changes are required.

Q: Why is BAS40XYF classified as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The BAS40XY,115 remains in active production and provides full functional equivalency, making it the recommended replacement for ongoing applications.

Q: What is the inventory status for BAS40XY,115?

A: BAS40XY,115 inventory is 52,668 pieces in new original stock, available in Cut Tape (CT) and Digi-Reel® packaging formats, ensuring reliable supply for production requirements.

Q: Are there any electrical performance differences between the two parts?

A: No. Forward voltage drop, reverse voltage rating, rectified current capacity, reverse leakage current, and junction temperature ratings are identical. Both components exhibit identical Schottky diode array performance characteristics.
