Engineering Selection Recommendations

The BAS316,115 is the designated manufacturer substitute for the obsolete BAS216,115. Selection of this substitute is supported by the following factors:

Product Status: The BAS216,115 is obsolete, while the BAS316,115 maintains active production status with substantial inventory availability (240,400 pcs), ensuring long-term supply chain continuity.

Electrical Performance: The BAS316,115 exceeds the minimum electrical requirements of the BAS216,115 across all critical parameters. The reverse voltage rating increases from 75 V to 100 V, providing additional design margin. Forward voltage, reverse recovery time, and junction temperature ratings remain identical, ensuring functional equivalence in switching applications.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status. The BAS316,115 carries AEC-Q101 automotive qualification, indicating enhanced reliability screening and process controls.

Package Transition: The shift from SOD-110 to SOD-323 packaging requires PCB layout modification. The SOD-323 package is smaller and more widely used in modern surface mount assembly processes, potentially offering manufacturing advantages in new designs.

Frequently Asked Questions (FAQ)

Q: Can the BAS316,115 directly replace the BAS216,115 without circuit modification?

A: Electrical substitution is valid. The BAS316,115 meets or exceeds all electrical specifications of the BAS216,115. However, the package change from SOD-110 to SOD-323 requires PCB footprint modification and assembly process adjustment.

Q: What is the significance of the increased reverse voltage rating (100 V vs. 75 V)?

A: The higher reverse voltage rating of the BAS316,115 provides additional design margin and allows operation in circuits with higher transient voltage spikes. This does not affect compatibility in applications designed for 75 V operation.

Q: How do the forward voltage characteristics compare?

A: Both parts specify identical forward voltage characteristics: 1.25 V maximum at 150 mA. This ensures equivalent voltage drop performance in rectification and switching circuits.

Q: What is the impact of the reverse leakage current difference?

A: The BAS316,115 exhibits lower reverse leakage current (500 nA @ 80 V) compared to the BAS216,115 (1 µA @ 75 V). This represents improved leakage performance and does not create compatibility issues in applications tolerant of the original leakage specification.

Q: Are there any thermal considerations for this substitution?

A: Both parts specify identical maximum junction temperature ratings of 150°C. Thermal performance is equivalent, and no thermal design changes are required.

Q: What packaging considerations apply to this substitution?

A: The SOD-323 package used by the BAS316,115 is smaller than the SOD-110 package of the BAS216,115. PCB land pattern, component placement, and assembly tooling must be updated to accommodate the new package geometry.

Q: Is the BAS316,115 suitable for automotive applications?

A: Yes. The BAS316,115 carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. The BAS216,115 does not specify automotive qualification.
