1N4151TR

Single Diodes Overview

The Fairchild Semiconductor 1N4151TR is a silicon signal rectifier diode housed in the DO-35 axial leaded package. It features a maximum average forward rectified current of 0.15 A and a maximum repetitive peak reverse voltage of 75 V. The device exhibits a maximum reverse recovery time of 0.004 µs, supporting fast switching applications. It operates within a junction temperature range of -65 °C to 200 °C with a maximum power dissipation of 0.5 W.

Single Diodes Feature Summary

• High-speed switching circuits
• Clamping and protection applications

Single Diodes Procurement Notes

Verify the specific manufacturer designation as multiple vendors produce this standard part number. Confirm compliance requirements such as RoHS status, as some variants may be lead-free while others are not. Ensure the package type matches the DO-35 specification and check for any specific military or industrial qualification markings if required for the design.

Single Diodes Selection Notes

Select this component when a small-signal diode with low reverse recovery time is required. The 75 V rating limits its use to low-voltage signal paths rather than power rectification. Consider the DO-35 package constraints for PCB layout and thermal management compared to surface mount alternatives like the LL4151.

Single Diodes Part Context

This component belongs to the standard 1N4151 series of fast switching silicon signal diodes. It is widely used in electronic designs requiring reliable performance in signal conditioning and switching roles. The DO-35 package provides a robust through-hole mounting solution compatible with legacy and modern circuit board technologies.

Single Diodes Replacement Considerations

Equivalent parts include the 1N4151T/R from NXP and the 1N4151.TR from Texas Instruments. Verify that substitute components maintain the same 0.15 A current rating and 75 V reverse voltage specifications.
