Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm marking codes or tape-and-reel specifications, as ordering suffixes may denote packaging variations without altering electrical function. Confirm compliance requirements such as RoHS and halogen-free status directly with the manufacturer's quality definitions before procurement.

Selection Notes

Select this component for applications requiring compact footprints and rapid switching performance. Ensure the 80 V reverse voltage rating exceeds peak circuit voltages and that the 150 mW power dissipation limit accommodates thermal constraints on the FR-4 PCB layout. Verify junction temperature limits during operation.

Part Context

This part belongs to the MMBD4448HT series, which includes variants like HTA, HTC, and HTS sharing identical electrical characteristics but differing in marking codes or packaging details. The series is designed for general-purpose high-speed switching tasks in consumer electronics and industrial control systems.

Replacement Considerations

Direct substitutes within the same family include MMBD4448HT-7-F, MMBD4448HTA-7-F, and MMBD4448HTS-7-F, provided pinout and marking compatibility are verified.
