1N4148-P-TR

Single Diodes Overview

The 1N4148-P-TR is a small signal fast switching diode manufactured by Vishay General Semiconductor - Diodes Division. It utilizes silicon epitaxial planar technology and is housed in the DO-35-2 through-hole package. The device features a maximum DC reverse voltage of 75 V and an average forward rectified current of 150 mA. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 75 V, a forward voltage drop of 1.25 V at 150 mA, and a reverse recovery time of 4 ns. It operates within a junction temperature range of -65°C to 175°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific suffix P-TR confirms the tape and reel packaging format directly from the manufacturer datasheet. Confirm the DO-35-2 package dimensions match your board layout requirements. Ensure the 175°C maximum junction temperature rating aligns with your system's thermal management strategy before finalizing component selection.

Single Diodes Selection Notes

Select this component when through-hole mounting is required for small signal fast switching applications. The 75 V reverse voltage rating suits low-voltage logic interfaces. Compare the 4 ns reverse recovery time against circuit speed requirements to ensure adequate performance for the intended frequency range.

Single Diodes Part Context

This part belongs to the 1N4148 family of small signal fast switching diodes. It shares functional equivalence with other industry-standard variants but is distinguished by its specific Vishay manufacturing process and DO-35-2 through-hole packaging configuration.

Single Diodes Replacement Considerations

Consult official Vishay documentation for electrically equivalent alternatives. Verify pinout compatibility and package dimensions when substituting with generic 1N4148 equivalents.
