Procurement Notes

Verify the authenticity of the component by purchasing directly from Micro Commercial Components or their authorized distributors to ensure traceability and quality. Confirm that the ordering suffix matches the specific package variant required for your design. Check for updated datasheet revisions before finalizing procurement specifications.

Selection Notes

Select this component when a compact footprint is required alongside fast switching performance. Ensure the circuit design accommodates the 80V peak reverse voltage limit and the 500mA forward current capacity. Consider the thermal resistance characteristics if operating near the upper temperature limits.

Part Context

This part belongs to the MMBD4448HT series, which includes variants like MMBD4448HTA and MMBD4448HTC. These devices share similar electrical characteristics but differ in marking codes and specific package configurations. The HTS designation specifically identifies the SOT-523 package form factor.

Replacement Considerations

Cross-reference with other MMBD4448 series parts from different manufacturers if pin compatibility is maintained. Verify that substitute components meet the same 4ns reverse recovery time and 80V blocking voltage requirements.
