Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm package type and marking code. Confirm that the component is sourced from authorized channels to ensure authenticity, as the product business transitioned to Nexperia. Check the most recently issued datasheet for any updates to specifications or status before initiating design or procurement processes.

Single Diodes Selection Notes

Select this component for applications requiring fast switching speeds and hermetic sealing in an axial leaded glass package. Ensure the circuit operates within the 100 V reverse voltage limit and 200 mA continuous forward current constraints. Consider thermal resistance values when designing for ambient temperatures exceeding 25 °C to maintain safe junction temperatures.

Single Diodes Part Context

This part belongs to the 1N4148/1N4448 series of high-speed diodes originally manufactured by NXP Semiconductors. The standard business unit was transferred to Nexperia in February 2017. The documentation reflects this transition, noting that references to NXP or Philips should be interpreted as Nexperia. The 1N4148 remains a widely used general-purpose high-speed switching diode.

Single Diodes Replacement Considerations

The 1N4448 is documented alongside the 1N4148 in the same datasheet with identical package and general switching characteristics, though it specifies different forward voltage limits.
