Overview
The MMBD4448HADW-7-G is a surface mount fast switching diode array manufactured by Diodes Incorporated. It features two pairs of common anode standard diodes housed in a compact SOT-363 package (also identified as SC-88 or 6-TSSOP). The device supports a maximum DC reverse voltage of 80 V and an average rectified forward current of 250 mA per diode. Key electrical characteristics include a forward voltage of 1.25 V at 150 mA, a reverse leakage current of 100 nA at 70 V, and a reverse recovery time of 4 ns. The junction operating temperature range extends from -65°C to 150°C.
Feature Summary
- Fast switching speed with low reverse recovery time for efficient signal handling
- Ultra-small surface mount package design suitable for space-constrained applications
- High conductance performance with low forward voltage drop
- Low reverse leakage current ensuring minimal power loss in off-state
Applications
- General purpose switching circuits
- Signal demodulation and detection
- Clamping and protection in high-speed digital lines
Procurement Notes
Verify the specific suffix against the manufacturer's official documentation to confirm compliance with RoHS directives and halogen-free status. Ensure the ordering code matches the required tape and reel quantity specifications. Cross-reference the package marking codes to distinguish between variants within the MMBD4448HA family. Confirm that the supplier provides valid traceability documents for quality assurance purposes.
Selection Notes
Select this component when a dual common anode configuration is required in a minimal footprint. The SOT-363 package offers a balance between thermal performance and board space efficiency. Consider the 80 V reverse voltage rating and 250 mA current capability relative to the circuit requirements. Evaluate the 4 ns reverse recovery time suitability for the intended switching frequency.
Part Context
This part belongs to the MMBD4448HA series of surface mount fast switching diode arrays. The series includes various package options such as SOT-363, SOT-23, and others. Diodes Incorporated produces this line for general-purpose applications requiring reliable switching performance. The HA variant specifically denotes the common anode configuration within the broader product family.
Replacement Considerations
Compatible substitutes include other MMBD4448HA series parts with identical pinouts and electrical ratings. Verify package compatibility before substitution. Check datasheets for minor variations in forward voltage or leakage current that may affect sensitive circuits.
