1N4448HWT-7

Single Diodes Overview

The 1N4448HWT-7 is a surface-mount fast switching diode manufactured by Diodes Incorporated in an SOD523 package. It features a peak repetitive reverse voltage of 80 V and a forward continuous current rating of 250 mA. The device exhibits a maximum reverse-recovery time of 4.0 ns and a total capacitance of 3.0 pF at 1.0 MHz. Operating temperature ranges from -55°C to +150°C, with power dissipation limited to 150 mW.

Single Diodes Feature Summary

• Fast switching speed suitable for high-frequency applications
• Ultra-small surface-mount SOD523 package design
• High conductance characteristics
• Lead-free and RoHS compliant construction

Single Diodes Applications

• General-purpose switching circuits
• Automotive electronics requiring specific change control
• High-speed signal processing

Single Diodes Procurement Notes

Verify the ordering suffix matches the required packing quantity, as the -7 suffix indicates a 3000-unit tape and reel carrier. Confirm compliance with AEC-Q100/101 standards if automotive qualification is necessary. Ensure date codes reflect green molding compound requirements for halogen-free specifications. Validate terminal finish and moisture sensitivity levels against assembly process constraints.

Single Diodes Selection Notes

Select this component when space constraints require an ultra-small SOD523 footprint instead of larger axial packages. Choose based on the 4.0 ns reverse recovery time for high-speed switching needs. Consider the 150 mW power dissipation limit and thermal resistance values for circuit layout planning. Verify that the 80 V reverse voltage rating aligns with system operating conditions.

Single Diodes Part Context

This part belongs to the 1N4448 family of fast switching diodes, adapted for surface-mount technology. While traditional 1N4448 variants utilize DO-35 axial glass packages, the HWT series employs plastic SOD523 encapsulation. This evolution supports automated insertion and reduced board space consumption while maintaining comparable electrical performance metrics.
