1N4148WT-7

Single Diodes Overview

The 1N4148WT-7 is a surface mount fast switching diode manufactured by Diodes Incorporated in an SOD523 package. It features a non-repetitive peak reverse voltage of 100 V and a continuous forward current rating of 250 mA. The device exhibits a maximum reverse recovery time of 4 ns and a total capacitance of 2 pF at 0 V reverse bias. Operating temperatures range from -55°C to +150°C, with power dissipation rated at 150 mW.

Single Diodes Feature Summary

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

Single Diodes Applications

• General purpose switching circuits
• Automotive electronics requiring specific change control
• Surface mount assembly processes

Single Diodes Procurement Notes

Verify the exact ordering suffix matches the required packing quantity, as the standard -7 suffix indicates a 3,000-unit tape and reel configuration. Confirm that the specific variant meets automotive AEC-Q101 qualification requirements if intended for IATF 16949 certified facility production lines. Ensure compatibility with moisture sensitivity level 1 standards during storage and handling procedures.

Single Diodes Selection Notes

Select this component when a compact surface mount solution is required for general purpose signal switching tasks. The SOD523 package offers a small footprint suitable for space-constrained designs. Consider the 4 ns reverse recovery time for applications demanding rapid transition speeds. Verify thermal management capabilities align with the 150 mW power dissipation limit under expected ambient conditions.

Single Diodes Part Context

This part belongs to the 1N4148 series of silicon epitaxial planar switching diodes. It serves as a surface mount alternative to through-hole variants like the DO-35 packaged 1N4148. The device utilizes a molded plastic green molding compound with UL flammability classification rating 94V-0 for enhanced safety compliance in electronic assemblies.

Single Diodes Replacement Considerations

Direct substitutes include the 1N4148WT-7-F and 1N4148WT-13 from Diodes Incorporated, which share identical electrical specifications but differ in tape and reel packing quantities.
