Selection Notes
- Select by the parameter limits in the table, then confirm the derating curves in the full specification before committing a design.
- Package and footprint dimensions are listed per part. Verify against your land pattern — the same series can ship in several case sizes.
- Where the series spans automotive and consumer grades, check the part number suffix. The electrical values may match while the qualification does not.
