1N4448HWS-7-F

Overview

The 1N4448HWS-7-F is a surface-mount fast switching diode manufactured by Diodes Incorporated. It features an SOD323 package and provides a peak repetitive reverse voltage of 80 V with an average rectified output current of 250 mA. The device exhibits a maximum reverse-recovery time of 4.0 ns and a total capacitance of 3.5 pF at 0 V and 1 MHz. Forward voltage ranges from 0.62 V to 1.25 V depending on the forward current, while peak reverse current is limited to 100 nA at 80 V. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Fast switching speed suitable for high-frequency applications
• High conductance characteristics
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony free green device

Applications

• General-purpose switching applications

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the 3,000-unit tape and reel carrier format. Confirm that the component meets the required environmental standards, including compliance with EU RoHS directives and halogen-free specifications. Ensure the selected part matches the SOD323 package outline dimensions and pad layout requirements for the intended PCB design.

Selection Notes

Select this component when a small surface-mount package is required for general-purpose switching tasks. The 80 V rating and 250 mA current capacity define its operational limits. Consider the 4.0 ns reverse recovery time for circuit timing requirements. Verify thermal dissipation capabilities against the ambient temperature conditions of the final assembly.

Part Context

This component belongs to the 1N4448HWS series of surface-mount fast switching diodes. It serves as a modern replacement for through-hole variants in compact electronic designs. The SOD323 package allows for automated surface-mount assembly processes. The product line emphasizes compliance with environmental regulations while maintaining standard switching performance metrics.

Replacement Considerations

The 1N4448HWS-13-F is an alternative version from the same manufacturer offering identical electrical characteristics but packaged in a 10,000-unit tape and reel carrier.
