MMBD4448HAQW-TP

Overview

The MMBD4448HAQW-TP is a small signal switching diode manufactured by Micro Commercial Components (MCC). It features a quad common anode configuration housed in an SOT-363 surface-mount package. Key electrical specifications include a peak reverse voltage of 80 V, a forward current of 500 mA, and a maximum surge current of 4 A. The device exhibits a fast recovery time of 4 ns, a forward voltage of 1.25 V at specified conditions, and a low reverse current of 100 nA. Power dissipation is rated at 200 mW, with an operating temperature range from -65 C to +150 C.

Feature Summary

• Quad common anode configuration for compact circuit integration
• Fast switching speed with 4 ns recovery time
• Ultra-small SOT-363 surface mount package design
• High conductance characteristics with low forward voltage

Applications

• General purpose switching applications
• High-speed digital logic circuits
• Signal demodulation and rectification

Procurement Notes

Verify the specific suffix 'HAQW-TP' against the manufacturer's official datasheet to confirm the quad common anode configuration and SOT-363 packaging. Ensure compatibility with RoHS directives if required by your assembly process. Cross-reference the part number with MCC documentation to distinguish it from similar variants like MMBD4448V-TP or MMBD4448DW-TP-HF which may have different pinouts or electrical ratings.

Selection Notes

Select this component when a quad common anode arrangement is required in a minimal footprint. The SOT-363 package suits high-density PCB layouts. Consider the 80 V reverse voltage and 500 mA forward current limits for circuit design. The 4 ns recovery time makes it suitable for faster switching frequencies compared to standard general-purpose diodes. Verify thermal management requirements given the 200 mW power dissipation rating.

Part Context

This part belongs to the MMBD4448 series of fast switching diodes from Micro Commercial Components. The series includes various configurations such as single, dual, and quad arrangements in packages like SOT-523 and SOT-363. The HAQW-TP variant specifically denotes the quad common anode version in the SOT-363 case, distinguishing it from other series members with different internal connections or package types.

Replacement Considerations

MMBD4448HAQW-7-F by Diodes Incorporated offers identical electrical parameters and the same SOT-363 quad common anode configuration. Verify pinout compatibility and package dimensions before substitution. Other MMBD4448 variants may differ in configuration or package, requiring careful review of datasheets.
