Procurement Notes
Verify the complete part number including the suffix to confirm the specific internal configuration variant. Confirm packaging details such as tape and reel quantities against official distributor listings. Ensure compliance with environmental directives like RoHS 3 and halogen-free requirements if specified for the target application. Cross-reference datasheet revision numbers to ensure accurate electrical parameters are used during design validation.
Selection Notes
Select this component when a compact dual series diode configuration is required in an SOT523 footprint. Consider the 4 ns reverse recovery time for high-speed switching needs. Evaluate the 150 mW power dissipation limit relative to ambient temperature derating curves. Verify that the 80 V reverse voltage rating exceeds the maximum circuit blocking voltage under all operating conditions.
Part Context
This part belongs to the MMBD4448HT family, which includes variants HTA, HTC, and HTS distinguished by internal pinout or connection configurations. All variants share identical electrical specifications and mechanical dimensions. The family is designed for space-constrained surface mount applications requiring fast switching capabilities.
Replacement Considerations
Direct substitutes within the same family include MMBD4448HT-7-F, MMBD4448HTA-7-F, and MMBD4448HTC-7-F. These parts share identical electrical ratings and package dimensions but may differ in internal polarity or connection schemes. Verify pin compatibility before substitution.
