Procurement Notes
Verify the specific suffix RHG against official Taiwan Semiconductor documentation to confirm exact tape-and-reel specifications and marking codes. Ensure compatibility with standard SOD-123 footprint designs. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement integration.
Selection Notes
Select this component when a compact, high-voltage switching diode is required for surface-mount designs. The SOD-123 package offers space efficiency compared to leaded alternatives. Consider the 200 mA current limit and 50 ns speed for appropriate circuit timing requirements. Verify thermal management needs for the specific application environment.
Part Context
This part belongs to the BAV21W series of small signal switching diodes. It serves as a surface-mount alternative to traditional leaded packages like DO-35. The device utilizes planar technology for reliable performance in general-purpose electronic applications requiring fast switching characteristics.
Replacement Considerations
Cross-reference with other manufacturers' BAV21 equivalents such as Nexperia or Vishay variants. Verify pinout compatibility and ensure electrical parameters meet or exceed the original design requirements. Check package dimensions for mechanical fit.
