Applications

• Ultra-high speed switching circuits
• Automotive electronic systems requiring robust component performance
• General-purpose signal processing applications

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the component status aligns with project requirements, as certain variants may be designated as not recommended for new designs. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing processes and quality standards.

Selection Notes

Select this component when high-speed switching performance is critical in a compact form factor. The common cathode configuration simplifies circuit layout compared to other arrangements. Ensure the operating voltage remains within the 90V peak reverse limit and that thermal management accommodates the specified power dissipation and temperature range for reliable long-term operation.

Part Context

This part belongs to ROHM's BAV70/BAW56/BAV99 series of small-signal switching diodes. These components are engineered for efficiency in space-constrained environments. The series offers various configurations to suit different circuit topologies while maintaining consistent high-speed characteristics and automotive qualification standards across the product line.

Replacement Considerations

The BAV70HY is listed as an active alternative with identical pinout and package dimensions. Verify that the substitute maintains the required AEC-Q101 qualification if automotive compliance is mandatory. Ensure all electrical parameters match the original design constraints before implementation.
