MMBD4448HADW-TP

Overview

The MMBD4448HADW-TP is a small signal switching diode manufactured by Micro Commercial Components. It features a dual configuration housed in an SOT-363 surface-mount package. Key electrical specifications include a peak reverse voltage of 80 V and a maximum forward current of 500 mA. The device exhibits a fast recovery time of 4 ns, with a forward voltage of 1.25 V and a reverse current of 100 nA. It supports a maximum surge current of 4 A and operates within a temperature range of -65 C to +150 C.

Feature Summary

• Dual configuration for compact circuit integration
• Fast switching speed with 4 ns recovery time
• Low forward voltage drop for efficiency
• Wide operating temperature range capability

Applications

• High-speed signal switching circuits
• Clamping and protection applications
• General purpose rectification in compact designs

Procurement Notes

Verify the specific suffix HADW against official datasheets to confirm pinout and electrical tolerances. Ensure compatibility with SOT-363 footprint requirements during PCB layout. Confirm RoHS compliance status through manufacturer documentation before final procurement decisions.

Selection Notes

Select this component when dual diode functionality is required in a minimal footprint. The 80 V rating suits low-voltage logic interfaces. Consider the 4 ns recovery time for high-frequency applications where standard diodes may introduce excessive delay or distortion.

Part Context

This part belongs to the MMBD4448 series of fast switching diodes from MCC. It shares core characteristics with variants like MMBD4448HSDW-TP but differs in specific packaging or handling attributes defined by the suffix. The series is designed for space-constrained surface-mount applications requiring reliable switching performance.

Replacement Considerations

MMBD4448HSDW-TP and MMBD4448HCDW-TP are documented variants within the same family. Verify pinout compatibility and exact electrical limits before substitution.
