Procurement Notes
Verify the component authenticity by checking the manufacturer marking code against official documentation. Confirm that the ordering suffix indicates RoHS compliance and halogen-free status. Ensure the package type matches the required SOD-123 footprint for PCB layout compatibility. Validate electrical parameters against the specific datasheet revision prior to integration.
Selection Notes
Select this component when a 100V reverse voltage rating and 250mA continuous current capacity are required in a compact surface-mount form factor. The AEC-Q101 qualification makes it appropriate for automotive environments. Consider the 4ns reverse recovery time for high-speed switching requirements where low junction capacitance is beneficial for signal integrity.
Part Context
This part belongs to the 1N4448 series of small-signal switching diodes manufactured by Micro Commercial Components. It serves as a surface-mount alternative to through-hole variants, offering similar electrical characteristics in the SOD-123 package. The HE3 designation typically implies specific manufacturing enhancements regarding environmental compliance and reliability within the MCC product line.
Replacement Considerations
Direct replacements include other 1N4448 series diodes in SOD-123 packages such as the 1N4448W or MMBD4448. Verify that substitute components meet the same AEC-Q101 automotive qualification if required for the application. Ensure equivalent reverse recovery time and forward voltage specifications are maintained.
