Procurement Notes
Verify the specific manufacturer suffix against official Diodes Incorporated documentation to confirm exact electrical tolerances and packaging details. Ensure the component matches the required SOD-123-2 footprint and lead-free compliance standards before integration into production designs.
Selection Notes
Select this component when a single-diode solution with 200 V reverse voltage and 200 mA forward current is required. The SOD-123-2 package offers space efficiency compared to through-hole alternatives. Consider the 50 ns recovery time for frequency requirements and verify thermal management needs for the specified operating temperature range.
Part Context
This component belongs to the BAV21 series of silicon epitaxial planar diodes. It is part of Diodes Incorporated's portfolio of small signal switching devices intended for general-purpose use. The series provides standardized specifications for reliability in consumer and industrial electronics.
Replacement Considerations
Cross-reference with other manufacturers' BAV21W equivalents such as those from Micro Commercial Components or Panjit. Verify pinout compatibility and ensure that reverse voltage and current ratings meet or exceed the original design requirements.
