1N4448TR_S00Z

Overview

The onsemi 1N4448TR_S00Z 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 of 200 mA. The device exhibits a fast reverse recovery time of 4.0 ns, with a maximum forward voltage of 0.72 V at 5.0 mA and a total capacitance of 2.0 pF at 0 V. Operating junction temperatures range from -55°C to +175°C.

Feature Summary

• Fast switching capability with a 4.0 ns reverse recovery time
• Hermetically sealed glass construction for environmental protection
• High thermal stability supporting operation up to 175°C

Applications

• General purpose switching circuits
• Clamping and protection applications
• High-speed digital logic interfacing

Procurement Notes

Verify that the specific S00Z suffix aligns with the required packing method or marking configuration as defined in the official ordering information table. Confirm compliance documentation availability for the target market before finalizing procurement specifications.

Selection Notes

Select this component when a high-speed silicon planar diode is required within a through-hole axial package. Ensure the circuit design accommodates the 100 V peak reverse voltage limit and the 200 mA average forward current rating under expected thermal conditions.

Part Context

This part belongs to the 1N91x and 1N4x48 family of small signal diodes manufactured by onsemi. It shares the same electrical characteristics and mechanical outline as other variants in the series, differing primarily in packaging format and specific orderable suffixes.

Replacement Considerations

Direct substitutes include 1N4448, 1N4448TA, and 1N4448T50A from onsemi. Cross-manufacturer equivalents such as the 1N914 are electrically compatible but may differ in specific leakage parameters.
