1N4148TR_S00Z

Single Diodes Overview

The onsemi 1N4148TR_S00Z is a small signal switching diode manufactured 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 supports a DC forward current of 300 mA and exhibits a fast reverse recovery time of 4 ns. Electrical characteristics include a maximum forward voltage of 1.0 V at specified currents, a maximum reverse leakage current of 5.0 µA at 75 V, and a total capacitance of 4.0 pF at 0 V bias.

Single Diodes Feature Summary

• Fast switching capability with a 4 ns reverse recovery time for high-speed signal processing
• High thermal stability supporting operation up to +175°C junction temperature
• Robust surge handling with non-repetitive peak forward surge current ratings up to 4.0 A

Single Diodes Applications

• General purpose signal switching circuits
• Clamping and protection applications
• High-speed logic interface isolation

Single Diodes Procurement Notes

Verify that the specific suffix matches the required tape and reel packing method for automated assembly lines. Confirm the component meets RoHS compliance standards relevant to your manufacturing region. Ensure the ordering code corresponds exactly to the DO-35 package variant to avoid mechanical fitment issues during installation.

Single Diodes Selection Notes

Select this component when a standard silicon switching diode with low capacitance is required. The DO-35 through-hole package is suitable for prototyping or environments where surface mount technology is not feasible. Consider the 100 V breakdown voltage as the primary limit for reverse blocking requirements in the target circuit design.

Single Diodes Part Context

This part belongs to the 1N91x and 1N4x48 family of small signal diodes produced by onsemi. The series includes variants such as the 1N914 and 1N4448, which share similar electrical profiles but may differ in specific leakage or capacitance parameters. The TR suffix indicates the standard tape and reel packaging format used for high-volume production.

Single Diodes Replacement Considerations

Compatible substitutes within the same family include the 1N914TR and 1N4148TA. Verify that alternative parts maintain the same DO-35 package dimensions and meet the 4 ns reverse recovery specification to ensure circuit performance parity.
