MMBD4448HCDW-7-G

Overview

The MMBD4448HCDW-7-G is a surface mount fast switching diode array manufactured by Diodes Incorporated. It features two dual common cathode configurations housed in an SOT-363 package. The device supports a maximum reverse voltage of 80 V and an average forward current of 500 mA per diode. Key electrical parameters include a forward voltage of 1.25 V at 150 mA, a reverse leakage current of 100 nA at 70 V, and a rapid reverse recovery time of 4 ns. Operating temperatures range from -65°C to +150°C.

Feature Summary

• Dual dual common cathode configuration for compact circuit design
• Fast switching speed with 4 ns reverse recovery time
• Low forward voltage characteristic for efficiency
• Ultra-small SOT-363 surface mount package

Applications

• General purpose switching applications
• High-speed signal processing circuits
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm compliance with RoHS directives and halogen-free status. Confirm that the SOT-363 package dimensions match your PCB footprint requirements. Ensure the 80V rating and 500mA current capacity align with your circuit's peak operational demands before finalizing procurement.

Selection Notes

Select this component when space constraints require a dual diode solution in a minimal footprint. The low reverse recovery time makes it suitable for high-frequency switching environments. Compare the 80V breakdown voltage against system transients to ensure adequate safety margins. Consider the thermal performance within the SOT-363 package for power dissipation limits.

Part Context

This part belongs to the MMBD4448 series of fast switching diode arrays from Diodes Incorporated. The series is designed for general-purpose switching applications requiring small form factors. Variants within the family may differ in packaging or specific electrical tolerances, but share the core fast-switching architecture optimized for modern electronic devices.

Replacement Considerations

Check for direct substitutes such as MMBD4448HCDW-7-F which shares identical electrical characteristics and packaging. Verify pinout compatibility and thermal resistance values when considering alternative manufacturers. Ensure any replacement maintains the 4 ns reverse recovery time specification.
