MBD4448HCDW REG

Diode Arrays Overview

The MBD4448HCDW REG is a small signal switching diode manufactured by Taiwan Semiconductor. It features a single diode configuration housed in an SOT-363-6 surface-mount package. Key electrical specifications include a peak reverse voltage of 57 V, a maximum forward current of 150 mA, and a surge current rating of 4 A. The device exhibits a fast recovery time of 4 ns with a forward voltage of 1.25 V and a reverse leakage current of 100 uA. It operates within a temperature range of -55 C to +150 C and has a power dissipation of 200 mW.

Diode Arrays Feature Summary

• Fast switching capability with 4 ns recovery time for high-speed signal processing
• Compact SOT-363-6 surface-mount package design for space-constrained applications
• High thermal stability supporting operation up to +150 C junction temperature

Diode Arrays Applications

• General purpose signal switching circuits
• High-speed digital logic interfacing
• Clamping and protection in low-voltage signal paths

Diode Arrays Procurement Notes

Verify the specific suffix 'REG' against official manufacturer documentation to confirm exact binning or revision status. Confirm RoHS compliance details directly from the datasheet as indicated in source records. Ensure the component is sourced from authorized distributors given its discontinued status to avoid counterfeit risks. Validate that the 57 V rating meets circuit requirements rather than assuming standard 80 V variants.

Diode Arrays Selection Notes

Select this component when a single-diode configuration is required instead of dual-array alternatives. The 57 V reverse voltage limit necessitates careful circuit analysis to prevent breakdown in higher voltage environments. Consider the 150 mA forward current constraint for load handling capabilities. The SOT-363-6 footprint requires compatible PCB land pattern design distinct from other SOT-363 variations.

Diode Arrays Part Context

This part belongs to the MBD4448HCDW series of small signal switching diodes. It differs from similar parts like the MMBD4448HCDW-TP which typically offers dual configurations and higher current ratings. The Taiwan Semiconductor variant is specifically noted as discontinued in distributor records. It shares the core silicon technology with other fast-switching diodes but is distinguished by its single-element architecture and specific voltage ratings.

Diode Arrays Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. The related MBD4448HCDW REG is listed as discontinued. Verify compatibility with MMBD4448 series components only if electrical parameters such as voltage and current ratings are strictly matched.
