1N4448W-7

Overview

The 1N4448W-7 is a fast switching surface-mount diode manufactured by Diodes Incorporated. It features a maximum DC blocking voltage of 75 V and a continuous forward current rating of 500 mA. The device exhibits a peak reverse recovery time of 4 ns and a total capacitance of 4 pF at 0 V. It operates within a junction temperature range of -55°C to +150°C and utilizes an SOD-123 package.

Feature Summary

• Fast switching speed for high-frequency applications
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony free "Green" device
• Qualified to JEDEC standards for high reliability

Applications

• General purpose switching applications
• Automotive electronics requiring specific change control
• High reliability circuits

Procurement Notes

Verify the exact ordering suffix, as variants such as 1N4448W-7-F exist with identical electrical characteristics but different packing quantities. Confirm that the SOD-123 package dimensions align with the target PCB footprint. Ensure compliance with RoHS 3 and REACH regulations if required by the end-use market.

Selection Notes

Select this component when a standard silicon signal diode with fast recovery characteristics is needed in a compact surface-mount form factor. The 75 V reverse voltage rating suits low-voltage logic and signal processing circuits. Consider thermal derating curves for high ambient temperature environments to maintain the 400 mW power dissipation limit.

Part Context

This part belongs to the 1N4448 family of fast switching diodes produced by Diodes Incorporated. It serves as a surface-mount alternative to through-hole equivalents, offering similar electrical performance in the SOD-123 package. The product line emphasizes environmental compliance and automotive-grade reliability options.
