Overview
The MMBD4448SDW is a small signal diode array manufactured by Diotec Semiconductor in the SOT-363 surface-mount package. It features four diodes configured in a bridge arrangement with a maximum repetitive peak reverse voltage of 75 V and an average forward current rating of 150 mA. The component exhibits a very low reverse recovery time of less than 4 ns, ensuring high-speed switching capabilities. Additional electrical characteristics include a junction capacitance of approximately 2 pF at 0 V and a power dissipation limit of 200 mW per device.
Feature Summary
- Four-diode bridge configuration within a compact SOT-363 surface-mount package
- Very low reverse recovery time for high-speed switching applications
- Low junction capacitance and leakage current for efficient signal processing
Applications
- High-speed switching circuits
- Signal processing systems
- Rectifying applications
Procurement Notes
Verify the specific ordering suffix when purchasing. Standard versions are commercial grade. Suffix -Q indicates AEC-Q101 compliance, while suffix -AQ denotes AEC-Q101 qualification. Confirm these designations match project requirements before procurement to ensure correct automotive or industrial grading.
Selection Notes
Select this component for designs requiring a compact bridge rectifier or fast switching array. The SOT-363 case minimizes board space usage. Ensure the 75 V reverse voltage and 150 mA forward current ratings exceed circuit demands. Consider the -Q or -AQ variants if automotive reliability standards are required.
Part Context
This part belongs to the Diotec SMD Small Signal Diode Arrays family, which includes BAS16DW, BAV70DW, and BAV756DW. These components share similar mechanical data and manufacturing processes but differ in internal configurations and voltage ratings. The MMBD4448SDW specifically utilizes a four-diode bridge topology distinct from the single or dual common cathode arrangements found in other series members.
Replacement Considerations
Cross-reference with BAS16DW, BAV70DW, or BAV756DW only if the application permits different internal configurations. Verify that alternative parts meet the 75 V reverse voltage and 150 mA forward current specifications. Check pinout compatibility for the SOT-363 package before substitution.
