1N4448HWT-7-G

Overview

The 1N4448HWT-7-G is a surface mount fast switching diode from Diodes Incorporated, encapsulated in an ultra-small SOD-523 molded plastic case. It features matte tin lead-free plating and is totally RoHS compliant and halogen-free. Key electrical parameters include a peak reverse voltage of 80 V, a forward current of 125 mA, and a maximum surge current of 4 A. The device exhibits a recovery time of 4 ns and a forward voltage of 1.25 V at specified conditions. Reverse current is limited to 2.5 uA. Operating temperatures range from -65 C to +150 C.

Feature Summary

• Ultra-small surface mount package for space-constrained designs
• Fast switching speed with 4 ns recovery time
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony free green device

Applications

• General purpose switching applications
• High frequency signal processing circuits
• Portable electronic devices requiring compact components

Procurement Notes

Verify the specific suffix -G confirms RoHS compliance and halogen-free status as per manufacturer documentation. Ensure the SOD-523 package footprint matches the design layout. Confirm that the 80V rating and 125mA current limits meet circuit requirements. Check for any specific handling instructions regarding the small form factor during assembly.

Selection Notes

Select this component when a fast switching diode is required in an ultra-small surface mount package. It serves as a suitable alternative to larger packages like SOT-23 or DO-35 when board space is limited. Consider the 80V reverse voltage and 125mA forward current capabilities against circuit demands. Verify thermal management needs given the small package size and power dissipation characteristics.

Part Context

This part belongs to Diodes Incorporated's line of surface mount fast switching diodes. It shares functional similarities with other small signal switching diodes but distinguishes itself through the SOD-523 package. It is designed for general purpose applications where high speed and small size are critical. The product line emphasizes environmental compliance and reliability for modern electronics manufacturing.

Replacement Considerations

Direct substitutes may include MMBD4448W-7-F or BAS19W, though package differences exist. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure the replacement maintains the required switching speed and voltage ratings.
