Overview
The MMBD4448HTS-TP is a single switching diode from Micro Commercial Components housed in an SOT-523 surface-mount package. It features a repetitive peak reverse voltage of 80V and a forward continuous current rating of 500mA. The device exhibits a maximum reverse recovery time of 4ns and a total capacitance of 3.5pF at 6.0V reverse bias. Power dissipation is rated at 150mW with a thermal resistance of 833°C/W. Operating junction temperature ranges from -65°C to +150°C.
Feature Summary
- Ultra-small surface mount package for general purpose switching applications
- Fast switching speed with high conductance characteristics
- Halogen-free green device compliant with RoHS standards
Applications
- General purpose switching circuits
- High-speed signal processing
- Low power rectification tasks
Procurement Notes
Verify the authenticity of the MMBD4448HTS-TP by purchasing directly from Micro Commercial Components or their authorized distributors. Counterfeit components pose significant risks; ensure traceability and adherence to MCC quality standards for handling and storage. Confirm that the ordering suffix indicates RoHS compliance as specified in official documentation.
Selection Notes
Select this component when a compact, fast-switching diode is required for low-power applications. The SOT-523 package suits space-constrained designs. Ensure the 80V reverse voltage and 500mA forward current ratings align with circuit requirements. Consider the 4ns recovery time for high-frequency operations where rapid switching is critical.
Part Context
This part belongs to the MMBD4448HT series, which includes variants like HTA, HTC, and HTS. All share identical electrical specifications but differ in device marking codes (AB for HTS). The series is designed for general-purpose switching, offering a balance of speed and power dissipation within a minimal footprint suitable for modern electronics.
Replacement Considerations
Direct substitutes include other MMBD4448HT series variants such as MMBD4448HT, MMBD4448HTA, and MMBD4448HTC, provided the specific device marking code is not a constraint. Cross-manufacturer replacements must match the 80V VRRM, 500mA IFM, and SOT-523 package dimensions.
