MMBD4448HCQW-7-G

Overview

The MMBD4448HCQW-7-G is a surface mount fast switching diode array manufactured by Diodes Incorporated. It features a quad common cathode configuration housed in an SOT-353 package. The device supports a maximum repetitive peak reverse voltage of 80 V and an average forward rectified current of 500 mA per diode. Key electrical parameters include a maximum forward voltage of 1.25 V at specified currents, a reverse leakage current of 100 nA at 70 V, and a rapid recovery time of 4 ns. The component operates within a junction temperature range of -65°C to +150°C and dissipates up to 200 mW of power.

Feature Summary

Quad common cathode architecture for compact circuit integration
Fast switching speed with 4 ns recovery time
Low forward voltage drop for improved efficiency
Automotive grade qualification under AEC-Q100 standards

Applications

General purpose high-speed switching circuits
Clamping and protection applications in consumer electronics
Signal processing in automotive electronic control units

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm exact packaging and tape-and-reel specifications. Ensure the procurement channel provides valid traceability for AEC-Q100 qualified components intended for automotive or industrial use. Cross-reference the manufacturer part number with the latest datasheet revision to confirm pinout compatibility and thermal characteristics before finalizing orders.

Selection Notes

Select this component when a quad common cathode configuration is required in a minimal footprint SOT-353 package. It is suitable for designs demanding fast recovery times and low leakage currents in space-constrained environments. Consider the 200 mW power dissipation limit and operating temperature range when evaluating thermal management requirements for the target application.

Part Context

This part belongs to the MMBD4448 series of surface mount switching diodes from Diodes Incorporated. The series includes variants such as MMBD4448HCQW and MMBD4448HADW, which share similar electrical characteristics but differ in package types like SOT-363 or TSSOP. The HCQW variant specifically denotes the SOT-353 housing with automotive qualification.

Replacement Considerations

Direct substitutes include other MMBD4448 series parts from Diodes Incorporated with compatible packages. Generic equivalents may be sourced from manufacturers offering quad common cathode diodes with matching 80V ratings and SOT-353 footprints, provided electrical parameters meet or exceed the original specifications.
