1N4148TR

Single Diodes Overview

The Vishay 1N4148TR is a silicon epitaxial planar small signal fast switching diode housed in the DO-35 (DO-204AH) axial leaded package. It features a repetitive peak reverse voltage of 100 V and a maximum DC reverse voltage of 75 V. The device supports an average forward current of 150 mA and a peak forward surge current of 2 A. Electrical characteristics include a typical reverse recovery time of 4 ns, a forward voltage of 1 V at 10 mA, and a diode capacitance of 4 pF at 0 V and 1 MHz.

Single Diodes Feature Summary

• Utilizes silicon epitaxial planar technology for high-speed switching applications
• Electrically equivalent to the 1N914 diode standard
• Provides extreme fast switching capabilities with low reverse recovery time

Single Diodes Applications

• Extreme fast switches
• General purpose signal rectification
• High-frequency circuit protection

Single Diodes Procurement Notes

Verify that the specific order code matches the required packaging configuration, such as TR/10K per reel or TAP/10K per ammopack. Confirm compliance requirements against the material categorization definitions provided by Vishay. Ensure the component meets the thermal resistance and junction temperature limits specified in the datasheet for the intended operating environment.

Single Diodes Selection Notes

Select this component when a small signal fast switching diode with axial leads is required. The 1N4148TR serves as a direct replacement for the 1N914 in existing designs. Consider the DO-35 package dimensions and the 175 °C maximum junction temperature when evaluating thermal management and physical space constraints within the target assembly.

Single Diodes Part Context

This part belongs to the Vishay 1N4148 series of small signal fast switching diodes. The 'TR' suffix indicates the device is supplied in tape and reel packaging, suitable for automated surface mount or through-hole insertion processes. The series is characterized by its standard silicon construction and robust electrical performance for general-purpose switching tasks.

Single Diodes Replacement Considerations

The 1N914 is electrically equivalent to the 1N4148. Verify pinout compatibility and package dimensions before substitution. Ensure the alternative component meets the same 100 V reverse voltage and 4 ns reverse recovery time specifications.
