1N4448_T26A

Single Diodes Overview

The onsemi 1N4448_T26A is a small signal switching diode housed in the DO-204AH (DO-35) axial lead package. It features a maximum repetitive reverse voltage of 100 V and an average rectified forward current rating of 200 mA. The device utilizes a silicon construction with a hermetically sealed glass body. Key electrical characteristics include a maximum forward voltage of 0.72 V at 5.0 mA, a total capacitance of 2.0 pF at 1.0 MHz, and a reverse recovery time of 4.0 ns.

Single Diodes Feature Summary

• Fast switching capability with low reverse recovery time for high-speed applications
• Hermetically sealed glass package ensuring environmental stability
• Low total capacitance suitable for high-frequency signal processing
• High thermal resistance junction-to-ambient for reliable operation

Single Diodes Applications

• General purpose signal rectification
• High-speed switching circuits
• Clamping and protection applications

Single Diodes Procurement Notes

Verify the specific ordering suffix _T26A corresponds to the Ammo packing method as listed in the official onsemi documentation. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the DO-204AH package dimensions align with your PCB footprint requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a fast-switching silicon diode with a 100 V reverse voltage rating is required. The 200 mA average forward current rating distinguishes it from lower-current variants like the 1N4148. The axial lead configuration is preferred over surface mount options when through-hole mounting or manual insertion is necessary for the design.

Single Diodes Part Context

This part belongs to the 1N91x, 1N4x48, FDLL914, and FDLL4x48 family of small signal diodes manufactured by onsemi. The family shares similar electrical performance profiles but varies in packaging and specific voltage sub-ratings. The 1N4448 variant specifically offers higher surge current capabilities compared to the standard 1N4148 within the same series.

Single Diodes Replacement Considerations

The 1N4148 serves as a functional substitute within the same family, though it has a lower non-repetitive peak forward surge current rating. Other equivalents include the FDLL4448 in a SOD-80 surface mount package if form factor changes are acceptable.
