Procurement Notes

Verify the specific ordering suffix against the official onsemi datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with current environmental directives such as RoHS and REACH requirements before finalizing procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm active status and availability.

Selection Notes

Select this component when a 40V reverse voltage rating and 200mA forward current capacity are required in a minimal footprint. Consider the SOD-323 package dimensions for PCB layout constraints. Evaluate thermal management needs based on the expected power dissipation and ambient operating conditions relative to the 175°C maximum junction temperature limit.

Part Context

This diode belongs to onsemi's portfolio of general-purpose small-signal switching diodes. It serves as a standard solution for basic rectification and signal protection tasks in consumer electronics and industrial control systems. The SOD-323 form factor aligns with industry trends toward miniaturization in modern printed circuit board assemblies.

Replacement Considerations

Consult official substitution guides for equivalent small-signal diodes with matching 40V reverse voltage and 200mA current ratings in SOD-323 packages. Verify pinout compatibility and electrical parameter tolerances before implementing any alternative components.
