Single Diodes Procurement Notes

Verify the manufacturer origin, as the component is produced by onsemi while distributed by ANBON SEMICONDUCTOR (INT'L) LIMITED. Confirm the specific package variant SOD-323F-2 matches the design requirements. Ensure compliance with RoHS standards and check for any recent product change notifications that may affect specifications or availability.

Single Diodes Selection Notes

Select this component for designs requiring a compact, fast-switching diode with moderate current handling. The SOD-323F-2 package suits space-constrained PCB layouts. Compare the 75 V reverse voltage and 150 mA forward current limits against circuit demands to ensure adequate headroom for transient conditions and continuous operation.

Single Diodes Part Context

This part belongs to the 1N4148 series of small signal switching diodes. It serves as a modern surface-mount alternative to through-hole variants, offering similar electrical performance in a significantly smaller footprint. The device is widely used in consumer electronics and industrial control systems where reliable fast switching is required.

Single Diodes Replacement Considerations

Direct substitutes include other 1N4148 variants in SOD-323 packages from different manufacturers. Verify pinout compatibility and ensure equivalent electrical ratings for reverse voltage and forward current before substitution.
