MMBD4448HTA-7-F

Overview

The MMBD4448HTA-7-F is a surface mount fast switching diode manufactured by Diodes Incorporated. It features a dual common anode configuration within an SOT523 package. The device supports a maximum repetitive reverse voltage of 80 V and a continuous forward current of 500 mA. Electrical characteristics include a typical reverse recovery time of 4.0 ns and a power dissipation rating of 150 mW at 25°C ambient temperature.

Feature Summary

Ultra-small surface mount package design
Fast switching speed with 4.0 ns reverse recovery time
High conductance for general-purpose applications
Totally lead-free and fully RoHS compliant

Applications

General-purpose switching circuits
DC-DC converter output rectification
Signal demodulation in communication equipment

Procurement Notes

Verify the specific ordering suffix to confirm the exact marking code and internal variant, as the HTA designation corresponds to specific marking codes distinct from other members of the MMBD4448HT family. Confirm compliance requirements against local regulations before finalizing procurement orders.

Selection Notes

Select this component when a compact dual common anode topology is required for high-speed signal processing or power conversion. Ensure the operating junction temperature remains within the -55°C to +150°C range and that thermal management accommodates the 833 °C/W thermal resistance characteristic.

Part Context

This part belongs to the MMBD4448HT series, which includes variants such as MMBD4448HT, MMBD4448HTC, and MMBD4448HTS. All variants share identical electrical specifications but differ in physical marking codes on the SOT523 package to distinguish between manufacturing lots or specific sub-types within the product line.

Replacement Considerations

Direct substitutes within the same family include MMBD4448HT-7-F, MMBD4448HTC-7-F, and MMBD4448HTS-7-F. These parts maintain identical electrical performance and packaging dimensions, differing only in the visible marking code on the component body.

FAQ

What is the total capacitance of the MMBD4448HTA-7-F?

The total capacitance is typically 3.5 pF when measured at a reverse voltage of 6V and a frequency of 1.0MHz.

Is the MMBD4448HTA-7-F suitable for automotive applications?

Standard versions are not explicitly qualified for automotive use. For automotive applications requiring AEC-Q100/101/104/200 qualification and IATF 16949 manufacturing, customers must contact Diodes Incorporated directly.
