• Qualified to AEC-Q101 standards for high reliability

Applications

• Low-leakage current applications in surface mounted circuits

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or direct channels. Confirm datasheet revision DS30258 Rev. 12-2 matches procurement specifications. Ensure packaging details align with tape and reel requirements. Check for RoHS compliance and green molding compound status based on date codes. Validate ordering information against official manufacturer documentation before finalizing purchase orders.

Selection Notes

Select this component for designs requiring minimal reverse leakage and compact footprint. The SOT-523 case reduces board space compared to larger packages. Consider the 150 mW power dissipation limit when determining thermal management needs. Verify that the 85 V reverse voltage rating meets circuit requirements. Ensure compatibility with automated assembly processes utilizing standard SMT equipment.

Part Context

This part belongs to a family including BAS116T, BAW156T, and BAV170T, all sharing the SOT-523 package. These devices are designed for general-purpose switching and low-leakage applications. The BAV199T variant specifically offers higher reverse voltage capabilities compared to some siblings. All variants maintain similar mechanical dimensions and mounting characteristics for interchangeability in specific layout constraints.

Replacement Considerations

BAV199T-7-F serves as a direct replacement for other BAV199T variants within the same package. Cross-reference with BAS116T or BAW156T only if electrical parameters like leakage and voltage ratings are compatible. Verify pinout and marking codes match existing board silkscreen. Ensure thermal resistance and power dissipation limits remain within acceptable bounds for the application.
